Passive seismic – Dam Repair in America’s Tsunami-Vulnerable Communities

Posted by on Friday, 30 October, 2015

by Gemma Barson, Oct.30, 2015


A new study by the U.S. Geological Survey and university researchers that was published earlier this year has discovered that of the 94,870 people living in tsunami hazard zones in northern California, Oregon and Washington state, about 21,500 would not have time to reach higher ground were a tsunami to hit their community.

For many communities and local authorities this has led to an increase in demand for vertical evacuation structures that would enable residents to evacuate safely without having to seek higher ground (perhaps in the form of a beam type structure, or the fortification of an existing high building). However, more important issues thrown up by this study are that the existing infrastructure within these communities are so old and potentially structurally unsound that, were a tsumani to hit, bridges would crumble and dams would fail, blocking the potential escape routes of tens of thousands of individuals and leading to significant loss of life.

This leads to a huge assignment for geophysicists who have been tasked with utilizing innovative new technologies that have developed in the field of passive seismic to image the subsurface and the incredible details that these can pick up in a non-intrusive way. Whilst it was first adopted (and still has very lucrative applications for) the sourcing of underground oil wells and other vital resources, passive seismic near-surface geophysics can also be applied in other incredibly useful ways. It can be used to ascertain the ways in which passive sources (such as nearby train stations or large car movement on a highway) can impact both on earth movements and the surface of the earth’s structure, as well as ascertaining the impact that these have, particularly on aging infrastructure such as these bridges, dams and levees.  It is clear that near-surface applications are both increasing in number, and that their societal value only continues to rise.

The Practical Considerations

The practical considerations that surround the field of passive seismic research are huge. Practitioners can choose to either temporary arrays deployment or, if they want to permanently monitor the seismic changes in a particular location, they can choose  permanently installed sensors: there are, of course, pros and cons associated with adopting both systems. The largest technical risk is the sensitivity of the system, and how it will be negatively affected by any external noise and change, whilst financial implications are also a huge concern. Because passive seismic imaging is a quickly growing technology, it can also be very expensive to undertake. The purchasing and maintenance costs of the equipment is huge, particularly when the costs of the vehicular support that is needed to transport the equipment and access remote monitoring locations, as well as the costs of insuring and protecting all of that equipment are taken into consideration. These costs could vary considerably depending on where you are based, and where you choose to purchase your equipment, with technological hardware and software, and any related insurances, generally being considerably more expensive in Europe (particularly in the UK) than in North America.

The Society for Exploration Geophysicists have recently announced their new president as John Bradford: a specialist in the field of passive seismic research and very vocal about the potential wider implications that the new technologies surrounding the field can have. It seems that under Bradford’s leadership, focus throughout the society will shift to focus on passive seismic research, to the benefit of those working within the field. Monitoring failure cases are likely to be minimized as the technology involved in the process develops, and this will only make it easier to ensure that the vital infrastructures on which all of our communities depend can be maintained and updates as necessary.

Climate change is happening, and more and more communities are under threat from tsunamis, increased earthquakes, and other natural disasters. By deploying passive seismic monitoring to help us best understand how to strengthen our infrastructure and ensure that our bridges, dams, and other vital services can be rebuilt or repaired in such a way that will minimize the impact of these natural disasters, we can use passive seismic systems for the benefit of our greater communities.

Airborne geophysics in Kazakhstan

Pioneer completes its first Commercial Multicopter UAV-MAG™ Survey

Posted by on Saturday, 11 July, 2015

by Michael Burns, President, Pioneer Exploration Consultants Ltd. on July,11, 2015

Pioneer Exploration Consultants Ltd. is a Canadian based geological consulting company that is quickly emerging as a leader in mining and exploration related UAV-based survey technology. Starting in 2014, they designed and built in-house a multicopter UAV-MAG™ survey system, and flew the first ever 590 line km multicopter-based survey.











Rather than waiting for a turn-key UAV based magnetometer system to hit the market, Pioneer came up with the idea of designing and building their own…

“Starting in the summer of 2014, we combined a proven UAV platform with a potassium vapor GSMP-35A magnetometer, resulting in a system with excellent performance specifications and survey capabilities. The UAV is a multicopter flight platform, chosen based on its payload capacity and flight time of about 30 min. The GSMP-35A potassium vapor sensor package is a proven airborne magnetometer with 0.0001 nT resolution, 0.3 pT sensitivity and 10 Hz sampling. The sensor package includes an ultra-light weight laser altimeter, GPS, and an IMU (inertial measurement unit) to record the sensor’s velocity, orientation and XYZ movement. The result was our UAV-MAG™ system which can fly up to 70 line km per day at an all in cost to the client of less than $100 per line km. Mobilization costs are the same as getting a person on site with 100 pounds of gear, due to the light weight and compact size of the UAV-MAG™, so rather than being a major cost addition to the survey, it’s becomes an insignificant expense.

To our knowledge, our survey costs are at least $40.00/ line km lower than anyone else on the market. This becomes a significant advantage for our clients, letting them put more resources into ground, and that’s huge for them.








Example of first vertical derivative results from two sample surveys, line spacing 50m, height 45m.

Our initial design focused on achieving three main goals:

1) To reduce magnetic interference of the flight platform in order to collect high quality magnetic data.

2) Create a system that is both reliable and flexible enough to fly a mag survey and collect aerial photos for orthoimagery and digital elevation models in the same day.

3) Create a highly portable system with the ability to fly a survey safely and simply in any terrain and under challenging weather conditions.

We achieved the first goal by employing a “towed bird” sensor configuration. The sensor is slung below the craft by a special designed light weight mount system, allowing sufficient craft-sensor separation and achieving low drag and no noticeable reduction in flight time. The remaining requirements pushed us away from fixed wing platforms and into multicopters for a number of reasons. With the UAV-MAG system, we can launch from the middle of a survey grid in heavily forested, steep terrain and not worry about takeoff and landing. Once in the air, the UAV-MAG™ takes care of the rest by flying the survey autonomously and returning home for landing. We found this invaluable for remote surveys. The small size of the platform, compared to a fixed wing system allows fast flight launching and easy transport. We can carry our fully flight-ready system by hand, ATV or vehicle, and launch within minutes. No complicated launching platforms, or landing fields required. What we have created is a truly versatile survey platform for multiple sensor packages, essentially a Swiss Army knife UAV, and our clients so far have been extremely pleased with the results and reduced survey costs.”

Mobile Technology: Making Field Work Easier

Posted by on Tuesday, 23 June, 2015

by  Gemma Barson, on June, 23, 2015

Smartphones and tablets have worked their way into almost all aspects of our lives, including work. While there has been an abundance of business related apps for some time now, it has taken a while for developers to set their sights on more niche areas. It wasn’t so long ago, for example, that the idea of carrying out field work or surveys accurately using a mobile device was laughable. Nowadays however, there are a number of advantages to using such devices in the field, from simply checking out the journals, to using high quality precision software. The fact that a tablet is considerably more transportable than a heavy piece of equipment is perhaps the most obvious advantage, but there are a number of others as well.

Cost and Practicality

Mobile devices and their potential, especially in the world of geophysics, have been a hot topic for some years now. The oil and gas sector was especially quick on the uptake of any mobile innovations, mainly due to the reliance on mobile technology that had already made itself indispensable to the more data focused areas of the industry. The main stalling point for more field focused areas of geophysics was the fact that many geophysicists were reluctant to engage with app programming. As the use of both cloud based computing and storage and mobile devices has proliferated, as well as the fact that mobile devices are now much more powerful, more apps focused on practical geophysical applications are appearing. This is mainly due to the fact that apps themselves are much easier and cheaper to program than when they first appeared. Now, geoscientists are able to apply their knowledge of their field directly into app form, and solve problems or streamline processes in such a way that makes a tablet a valuable piece of field kit. Another advantage to the proliferation of these specialist apps is they are highly customisable – a feature that is often missing from more unwieldy field equipment. Mobile techs and specialist apps have, as a result, opened up a whole new range of possibilities for all levels of projects for geoscientists across the world. One slight drawback of course, is that tablets can be quite fragile, and are not generally designed to withstand wilderness locations. This can be offset by the fact that cloud computing offers a secure, always accessible storage option for key data. Scientists can also take the simple step of making sure their equipment is protected from damage in case of accident.

Popular Apps

In recent years, a number of geoscience solution providers have also turned their attention to app development, either as standalone products or as companion software to other devices or software. The AGI SuperSting is one such example, which allows a number of remote functions to be performed on the SuperSting equipment, as well as a number of functions. The CSEMoMatic is another example of full service modelling software in app form, which could prove to be extremely useful on a field trip. Mobile database apps in particular are especially popular, and are effectively closing the gap between the expensive kit that is exclusively available to scientists, and everyday technology.


Utah University showcased the value and practicality of a geophysics focused app with the High Density Large Woody Debris app which was used for a large scale stream restoration project. As apps get even cheaper and easier to make, increasingly complex science can slowly make its way into the public domain. With the right tools for example (in app form), there is nothing to stop community and citizen science projects from undertaking experiments projects that would previously have required professional level equipment and software.

For the professional world, the use of database apps to streamline field readings, and data flow in general, is likely to have some far reaching, positive benefits to not only geophysics, but the sciences in general. Coupled with cloud computing, increasingly powerful tablets and mobile devices, as well as more wide reaching, faster Wi-Fi access, it might not be long before the tablet and a number of trusty apps are the most important part of any geophysics expedition or field study. Geophysics may not be alone in these developments either, as more and more scientific fields are embracing the power of the app.

Foreign investments in mineral exploration in Kazakhstan

Posted by on Monday, 27 April, 2015

Galym Nurjanov (a head of JSC “National exploration company “Kazgeology”) has held a press conference at RSU “Central Communications Service for the President of the Republic of Kazakhstan” and reported about success in investments attraction in the mineral exploration sector of Kazakhstan economy.

Over the past two years the four major foreign investors came to Kazakhstan – the Australian-British concern “Rio Tinto”, a South Korean corporation “KORES”, the Australian company “Iluka Resources” and the German investment fund “ULMUS FUND”. These companies are willing to invest into the mineral exploration sector over $ 5.5 billion tenge.  Airborne geophysical surveys are going to be started soon in connection with Rio Tinto and Iluka Resources projects. The advanced airborne geophysical technologies including VTEM and ZTEM which are used right now in Kazakhstan, have been brought by Canadian company Geotech Ltd.

Factors of Modern Discoveries

Mineral Exploration Strategies

E&MJ News published an article by Steve Fiscor where some factors of new mineral deposits discoveries have been outlined – these factors include applying modern geophysical technologies. The author provides some examples – airborne EM (VTEM, ZTEM), airborne gravity gradiometer, and airborne radiometric surveys which played key role in discoveries of mineral deposits.

“All of the discoveries were in the zone of other major discoveries, but most of them had been overlooked for one reason or another. The motivation could only be attributed to a geologically motivated hunch. New technology in the form of deep-penetrating airborne surveys allowed ground-based geophysical surveys to target undiscovered anomalies. Combining the new information with what they knew historically, exploration geologists were able to improve the drilling programs to quickly determine a resource.”

The next discoveries made with airborne geophysical technologies:

Albany Ultra-pure Graphite – VTEM survey

The Balboa Discovery at Cobre Panama – ZTEM survey

Kennady North Kimberlite Discoveries – airborne gravity gradiometer survey

PLS High Grade, High Techand Contrarian – airborne radiometric survey



Supervised Neural Network Targeting and Classification Analysis for Mineral Exploration

Posted by on Tuesday, 29 April, 2014

Karl Kwan (Geotech LTD) presented at Canadian Exploration Geophysical Society meeting (8 April 2014) methodology and examples of using Neural Network Targeting and Classification at mineral exploration.

“Geophysical survey contractors routinely offer multi-parameter data to clients. For example, a helicopter-borne survey may acquire Time-domain electromagnetic (TDEM), magnetic gradiometer and even gamma-ray spectrometer data (i.e., VTEMplus, Geotech LTD). Exploration geophysicists can certainly take advantage some of the readily available multi-disciplinary (geology, geophysics and remote sensing) and multi-parameter (potential field, EM, gamma-ray spectrometry, and others) datasets for mineral exploration. However, the integration and interpretation of these datasets can be time-consuming and even challenging, especially for large-scale datasets covering large areas with diverse geological conditions. The Supervised Neural Network (NN) Targeting and Classification technique for mineral exploration described and demonstrated by Reford, Lipton and Ugalde, 2004, “Predictive Ore Deposit Targeting Using Neural Network Analysis” (, can be a useful and promising tool for the analysis of multi-disciplinary and multi-parameter data.

In this presentation, the properties or responses of the two feed-forward multilayer Neural Networks, Levenberg-Marquardt (NN with LM training) and Fast Classification (FCNN), as implemented in the current version by PGW, are studied in detail. The supervised NN simulations are performed on specially constructed synthetic data. Intended as a tutorial and the NNs treated as black boxes, the objectives of the exercise are twofold, to demonstrate the targeting as well as classification capabilities of the Neural Networks, and at the same time to show one of the known limitations and to suggest a way to get around it. The utility of the NN tool is demonstrated again with real cases from the Republic of Niger.”

Airborne EM for permafrost mapping

Posted by on Wednesday, 25 January, 2012

ANCHORAGE, Alaska — A tool used by mining companies to find mineral ores has been adapted to map frozen soils below the ground in Alaska and could be used to track the effects of global warming, according to the U.S. Geological Survey.

The agency announced Monday that an airborne survey conducted in Alaska’s Yukon River drainage collected unprecedented images of the presence and absence of permafrost down to 328 feet. The study used an electromagnetic survey tool flown beneath a helicopter.

“We really think we’ve got the story nailed down from these data,” research geophysicist Burke Minsley said by phone from the Crustal Geophysics and Geochemistry Science Center in Denver.

Minsley is lead author of the study published Friday in the journal Geophysical Research Letters (

Mapping permafrost extents has been done by satellite, Minsley said.

“It’s hard to get any information at depth, and that’s what’s unique here,” he said.

Permafrost is below about 24 percent of the land area in North America. The research will be important for climate scientists looking at the thawing of permafrost as a greenhouse gas contributor, studying ecology in lake systems, or looking at the effects of thawing ground on river chemistry, Minsley said. Thawing also will bring important impacts for northern infrastructure such as buildings and roads.

The Yukon River begins in Yukon Territory, Canada, and spans Alaska from east to west.

The research team surveyed more than 116 square miles of the Yukon Flats in an area centered 140 miles northeast of Fairbanks. The area was picked in part because it’s between continuous permafrost to the north and discontinuous permafrost to the south, according to the agency.

Electromagnetic surveys have been used in mining for years, Minsley said. Scientists recently have used it to define the geometry of aquifers in Nebraska.

“What’s new about it is that it’s being used for more discrimination of more subtle features related to things like groundwater and permafrost,” Minsley said.

The tool is torpedo-shaped and about 33 feet long. In front are coils oscillating at different frequencies, Minsley said. Towed by a helicopter and flown just under 100 feet off the ground, the tool sends electromagnetic pulses into the ground and determines what’s below by measuring how well the pulse is conducted. The ground itself has conductors and resistors. Permafrost is not as conductive as solid ground.

“It induces currents in the ground. Those currents induct a signal, a magnetic field, that’s picked up by another set of coils that’s in the back of that thing that we’re towing under the helicopter,” Minsley said.

The tool collected data that showed a lack of permafrost below the Yukon River and other water bodies that don’t completely freeze in the harsh interior Alaska winter.

“That’s consistent with a lot of conceptual models that people have developed, but they haven’t really had the solid measurements that we have to see that,” Minsley said.

The mapping also showed “thermal relics” where the Yukon River had been centuries ago. As the river migrated to a new location, ground slowly refroze. The farther away from the new location, the more it had frozen in a downward slope. Minsley said it was the biggest surprise of the study.

“It was not something we expected to capture in this data set, to actually see that thermal legacy over a thousand-year history. That’s pretty rare for this kind of data,” he said.

The tool collected data over only one week in June 2010. Minsley said he spent four to five months analyzing and processing data to make images, and the research team spent many more hours interpreting the results.

Drilling boreholes to acquire the same information would have taken a much greater effort, he said.


Technology tie ups boost seismic sensing capabilities

Posted by on Sunday, 7 August, 2011

Shell and HP have announced a breakthrough in the capability of their jointly developed inertial sensing technology to shoot and record seismic data at much higher sensitivity and at ultra-low frequencies.

The new onshore wireless seismic acquisition system is designed to provide a clearer understanding of the earth’s subsurface, thus increasing prospects for discovering greater quantities of oil and gas to meet the world’s increasing energy needs.

The sensing technology has now been demonstrated to have a noise floor – a measure of the smallest detectable acceleration over a range of frequencies – of 10 nano-g per square root Hertz (ng/rtHz), which is equal to the noise created by the earth’s ocean waves at the quietest locations on earth as defined by the Peterson low noise model. The tests were conducted in the seismic testing vault at the US Geological Survey’s (USGS) Albuquerque Seismological Laboratory facility in New Mexico.

The seismic system uses the breadth of HP’s technology development capabilities as well as Shell’s advanced geophysical expertise in seismic data acquisition systems and operations. As such, this collaboration builds on the core strengths of each company to advance technology in this field.

The system will be delivered by HP Enterprise Services and the company’s IPG. It is based in part on the high-performance sensing technology originally co-developed by HP Labs – the company’s central research arm – along with IPG and Shell research in seismic network design.

Mapping the footprint of ore deposits in 3D using geophysical data

Potential field data provides alteration signatures

Linking geology and geophysical data

Chemical alteration in 3D

3D inversion of geophysical data

Changes in alteration types

This technique has allowed us to attribute anomalies in physical properties, with respect to the ‘normal’ host properties, with an expected alteration type. The technique is particularly applicable in the Cobar region because there is limited physical property contrast between host units and alteration is the predominant cause of geophysical anomalies. The technique is also applicable in regions that are under significant cover. As with any geophysical technique, the exact results will depend on the property contrast from host to altered product. A strong host-to-host property contrast will require a more detailed geological model to obtain the best results, but mapping of gross alteration trends should still be possible with only a very simple inversion reference model.

The history of seismic resolution from John and Les Denham

Posted by on Friday, 18 February, 2011
Actual time resolution achieved in typical seismic exploration has not improved since 1930. There appears to be an abrupt drop in resolution at the time when multifold techniques were introduced about forty years ago, and since then there may have been a slow improvement in resolution; but the achieved resolution is still not as good as that achieved in the very earliest reflection surveys. Many of the techniques used to improve other aspects of the data – signal-to-noise ratio, horizontal resolution and lithology discrimination, in particular – probably limit time resolution. In most projects there is a trade-off between cost, resolution and noise. The chosen techniques always seem to result in similar resolution, and this suggests that the cost – in money or other desirable signal characteristics – of improving resolution beyond this level is very high.

Kim Frankcombe – How real is Real Section IP?

Posted by on Friday, 18 February, 2011
Real Section is a pseudosection plotting method developed by Perparim Alikay and is described in a paper by Langore et al. (1989). It was originally based on a Schlumberger array but has been generalised more recently to gradient arrays. It assumes the plot depth for the pseudosection is between 0.125 and 0.2 of the current electrode separation A–B. According to the Langore paper, the factor to use in a given area was derived empirically from drill hole control. These values compare well with those given earlier by Edwards (1977) of 0.103 near the edges of the array to 0.192 at the centre. These are the depths at which, for a half space, half the signal comes from above the plot point and half from below. Despite the prevalence of relatively cheap 3D inversion software, the Zeus data is plotted in Real Section form for presentation to geologists rather than as inversions with sensitivity cut offs.

Two kilometres with time-domain AEM

Posted by on Friday, 18 February, 2011

Newly acquired data from an Airborne Electromagnetic (AEM) survey has revealed geological features to depths below the Earth’s surface well beyond any previously recorded by airborne systems.
The Versatile Time Domain Electromagnetics (VTEM) system operated by Geotech penetrated to depths approaching two kilometres which allows detailed identification of particular features and major structures at depths greater than has been mapped previously using AEM methods.
The data was acquired by Geoscience Australia in the Pine Creek region of the Northern Territory as part of its Onshore Energy Security Program to obtain pre-competitive data in areas which are considered to have potential for uranium or thorium mineralisation.
Prior to the enhancement of the VTEMTM dataset, AEM systems used throughout the world had been able to achieve imaging to a maximum depth of about 800 metres.
An enhanced set of conductivity estimates for the Kombolgie region within the Pine Creek survey area are available as a free download.
Geoscience of Australia selected the VTEM system to fly the Kombolgie survey from the various candidates submitted by members of the Panel of AEM contractors after an assessment of the probability of detecting hypothetical geological targets in the presence of a given background. GA selected the VTEM system to fly the Kombolgie surveyfrom the various candidates submitted by members of the Panelof AEM contractors after an assessment of the probability of detecting hypothetical geological targets in the presence of agiven background.

NEOS’s G&G methodology

Posted by on Sunday, 30 January, 2011

NEOS believes that an integrated analysis of multiple geological and geophysical (G&G) data sources – including seismicgravitymagneticelectromagnetic (EM), radiometric, and hyperspectral – can individually and collectively deliver improved insights into the rocks and fluids contained within the Earth.

“NEOS was formed to be a different kind of geosciences company where “Silicon Valley meets the oil patch.” We aspire to help our clients unlock the riches of the Earth by bringing to bear the latest technologies and the best people, wherever they might be located.”

One of our largest investors is the venture capital firm Kleiner Perkins Caufield & Byers (KPCB), the entity that backed pioneering companies such as Google, Symantec, Amazon, and Electronic Arts. By tapping into the networks of KPCB and our two other lead investors – Goldman Sachs and Passport Capital – we ensure our methods incorporate the latest thinking in sensors, computing, neural networks, visualization and intelligent search.

NEOS has been working over the last several years with leading technologists to develop the NeoSphere™, their proprietary data management system that allows a statistically-driven, multivariate inversion to be performed using all available data and modeling products. NEOS’s multi-measurement inversion incorporates all G&G data that has been obtained, acquired, or computed, along with additional geochemical and hydrocarbon production (and mineral resource) data provided by our clients and third parties.

Fixed Wing

NEOS generally uses company-owned Twin Otter aircraft for airborne sensor deployment. The Twin Otter offers a reliable platform that is capable of operating in remote, low-service locations. NEOS’s Twin Otter platforms are outfitted with advanced gravitymagnetic, and hyperspectral sensors.  NEOS’s hyperspectral sensor package records more than 600 contiguous channels – from ultraviolet to thermal infrared – with a spatial resolution of 3m. The Twin Otter is also capable of safely operating across a range of altitudes, providing the flexibility needed to tailor acquisition to the resolution and penetration depths required by the subsurface imaging objectives.


NEOS does not own or operate satellite systems, but instead licenses existing geophysical datasets – primarily low-resolution hyperspectral data from known satellite operators.  The ready availability, wide areal coverage, and cost effectiveness of most satellite datasets adds to their appeal. While the quality of satellite-based hyperspectral data(100 channels, ~10m resolution) is insufficient for detailed basin-level or prospect-level mapping, it is usually sufficient to feed into our neoSCAN ‘quick look’ solution.

Rotary Wing

When the next level of resolution and subsurface penetration is required, NEOS secures widely available helicopter platforms capable of deploying our advanced sensor payload system. Towed beneath the helicopter at an elevation of 30 meters above the ground, our typical rotary-wing payload package includes electromagneticradiometric, high resolution magnetic, hyperspectral, and gas detection sensors that NEOS has refined and optimized for natural resource mapping.
