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.

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.

The new EM system utilizing natural source

Posted by on Wednesday, 22 June, 2011

The well-known Schumann Resonance phenomena of the ionosphere produce clearly discernable electromagnetic waves. The Schumann Resonance frequencies of interest are 7.8, 14.3, 20.8, 27.3 and 33.8±1.0 Hz with a spectral band width of approximately 20%. Their peak strength usually is at around 10, 16 and 22 hours GMT. The measurements are energized by the electromagnetic energy of the Schumann resonances as well as the energy of the so-called 1/f noise of electromagnetic waves with frequencies around one Hertz and below. The observable strength of these electromagnetic waves will include variations because of leakage into the earth at a rate that will vary as a function of local geophysical properties. They can be received on, in or above the surface of the earth or in the sea waters. These modified electric (E-type) and magnetic (B-type) emissions (the signal we are interested in) are very small when compared to the other electromagnetic signals (which are considered to be noise). This invention is used to locate geophysical anomalies by determining where electromagnetic waves are potentially modified by geophysical anomalies.

It includes a moving platform equipped with a recording unit for recording the position of the platform. The system also comprises three first measuring units or sensors, adapted to record a varying electric field strength and a varying magnetic field strength at chosen intervals and thus positions, said first measuring units being adapted to measure said field strengths in three independent and mutually orthogonal directions at frequencies in a chosen range. The system includes a calculation unit for combining the measurements from each of said first sensors and calculating and recording as well as comparing the field strength vectors of the varying measured fields at each position, to find anomalies.

The purpose of the invention is to recognize the presence of anomalous volumes of material, their nature, depth, geographical location and extent below the surface of the earth by passively detecting relative differences in the natural electric (E-type) and magnetic (B-type) emissions in three dimensions; more specifically the field strengths are measured by a 3D sensor system that moves in a survey area of interest on or over land or above, on, or under water. This is achieved through recognizing relative differences in signal characteristics of continuous measurements in a survey grid. More specifically the objects stated above are obtained by a system and method characterized as stated in the accompanying independent claims.


The novel spectrometer systems and smart software

Posted by on Sunday, 30 January, 2011

Medusa Explorations from Netherlands is developing sensors for gammaray surveys. They are proud to see how their radiation sensors are used around the world for mapping soil properties in every detail needed.

“It is not only our technical skills that create good sensor systems. Our own surveyors are our most demanding clients, focussing development to robustness and useability of our sensors

and software.”

Measuring gamma radiation is not simple. Or rather, it is; the problems arise in the interpretation of the data, which will be influenced considerably by the type of detector used, the shape of the hole drilled and any number of other variable factors affecting the measurements. Medusa has developed a system where every gamma tool can be calibrated. The software results in flawless analyses of the measured results. This is one way not to be tripped up by the measuring equipment. Indeed, the software is the very essence of user friendliness: one button is all you need. Medusa’s software is also suitable to re-analyse old data.

3D modeling of ERA’s gradient survey results

Posted by on Friday, 14 January, 2011

UBC-GIF has finished 3D modeling of resistivity gradient survey data with EH3Dinv code. EH3Dinv is a computing code developed at UBC − GIF for inverting controlled source frequency-domain EM data to recover a 3D electrical conductivity (Inversion of 3D electromagnetic data in frequency and time domain using an inexact all-at-once approach. Eldad Haber, Uri M. Ascher, and Douglas W. Oldenburg. GEOPHYSICS, VOL. 69, NO. 5, 2004; P. 1216–1228).

The ERA’s technology, in brief, is “cross-disciplinary” – between frequency-domain and direct current (DC) concepts. The technology provides high resistivity resolution by grounded, non-contact and/or combined modes of electrical field measurements at 1.22-2500Hz. In comparison with DC method ERA equipment is several times more sensitive and in comparison with frequency-domain is defined as high-resolution.

SSW – New High-Tech Weapon

Posted by on Sunday, 5 September, 2010

The SSW Probe developed by Instrumentation GDD Inc. It reduces dilution and increases ore grade within mining operation.

Several mines use the GDD SSW probe to log nickel, copper and iron sulphides in blast holes. By lowering the probe in the blast hole, a profile of the electromagnetic (EM) response is measured and obtained in real time making it useful for finding out ores content. Indeed, logged drill holes in nickel mines have demonstrated that ores content of nickel, cobalt, copper, and PGM are often proportional to the intensity of the probe EM response. Quick and inexpensive, probing a 30 m depth blast hole within 10 cm intervals will take less than 2 minutes.

Surveying a drill hole with a GDD SSW probe helps to determine the shape of the high-grade ore body within the waste rock and low grade ore. Using this tool, user will know exactly where to stop blasting thus saving time and money. The SSW probe can also be used to discover and mine pockets of rich ore that are otherwise left in place. Increase ore grade at the mill and get rid of the waste!

About accuracy of proton magnetometers

Posted by on Friday, 26 February, 2010


Absolute accuracy of а measurement is the difference between measured and true values. Obviously, nobody knows the true value, so we end up defining the limits we know the true value must be within. Absolute accuracy of а measurement is the difference between measured and true values.Obviously, nobody knows the true value, so we end up defining the limits we know the true value must be within. There are numerous difficulties and conditions that must be fulfilled to obtain that kind of absolute accuracy. Proton magnetometers, although theoretically of higher absolute accuracy, require tender care if the highest accuracy is ever to be achieved.  The highest absolute accuracy of the magnetic field measurement has a metrological importance, but very little beyond this.

Aggressive geophysical activity of Pure Nickel in Alaska

Posted by on Friday, 5 February, 2010

The 2009 Exploration Program at the MAN, Alaska project included a new ZTEM airborne survey (Z axis Tipper Electromagnetic system), extensive geological mapping and a proprietary fluxgate time domain ground EM surveys (full waveform streaming multi sensor fluxgate array).  The 2009 geophysical programs (ground fluxgate TEM, ZTEM, and BHEM) were considered a great success.  These very compelling geophysical targets, are the best discovered to date on the MAN property and the foundation for a productive 2010 exploration program.

3D inversions of aeromagnetic data, as well as several widely spaced deep drill holes show a consistent presence of abnormally thick ultramafic bodies with localized deep feeders. Last year’s results add to the evidence that the MAN property is the main intrusive centre for Triassic magmatism that generate the extensive nickel, copper and PGE (platinum group elements) bearing ultramafic intrusions and coeval lavas within the Alaska, Yukon and BC, segments of the Wrangelia terrain.  Drill results to date come from the holes targeted using the proprietary ground time domain EM survey (TEM), in conjunction with the new ZTEM airborne survey and previous ground gravity and VTEM airborne surveys.

Interpretation of the 2009 MAN drilling results assays indicates the presence of a disseminated NI-Cu PGE (platinum group elements) concentration build up extends beyond 600 meters in DDH PNI-09-024 and over 1000 meters in DDH PNI-09-025.  Geophysical surveys show that these conductive bodies are associated with the strongest Fluxgate TEM anomalies on the property,  in addition, strong responses to the BHEM surveys indicates late channel (high conductance channels) conductivity build up beneath the drill holes.

The surveys described below were used to model the interpretation of conductive anomalies on the property. The analysis concludes that the anomalies are deep, large and very compelling.

  1. ZTEM Survey – has for the first time identified at depth the shape structure, and conductive zones of the mafic and ultramafic intrusions.
  2. Ground TEM – proprietary long time constant, time domain electromagnetic surveys allowed for deep search (> 800 meters) for high conductance bodies commonly associated with Ni-Cu sulphides that have been missed by previous surveys methodologies.
  3. Ground and Airborne Magnetic Survey’s – these survey’s help to define the magnetic bodies below surface that often correlate to the ultramafics and mafic rocks on the property.  In addition, UBC 3D inversions and Euler 3D inversions are employed to help determine the location of the form, internal structure, and deep kneels or feeder dykes associated with the intrusive bodies.
  4. BHEM Survey – a borehole electromagnetic survey is performed down the drill hole to detect conductive anomalies within, beside and below the drill hole to aid in the correlation with the new high priority, long time constant, surface TEM survey results constraining more accurate location of the conductor.

One of the most exciting targets from the 2009 geophysical program was the identification of the location for drill-hole PNI-09-025 based on the initial results from the TEM surveys.  The hole was drilled to a depth of 1066 metres and terminated due to the limitations of the drill.  The BHEM (down hole geophysical survey) showed an increasingly large response towards an anomaly below the hole’s final depth.

Low-frequency borehole electromagnetic surveys (BHEM) were carried out in five of the 2009 drill holes, as well as seven older drill holes. A number of moderate to strong off-hole conductors were detected and are being evaluated as follow-up drill targets for the 2010 program. Three holes (07-001, 09-023 and 09-025) show anomalous increases in late time channels indicative of deep conductors below the base of the holes. These deep conductive zones correlate with high-priority long time-constant surface TEM anomalies.

Extensive geophysical work was conducted concurrent to the drilling program.  In particular, a new ground time domain EM system (full waveform streaming multisensor fluxgate array), was deployed extensively through the latter half of the exploration season.  This was the first instance of this technology being used in North American nickel exploration.  This ground based EM technology developed by Dr. Mark Shore (Magma Geosciences Inc.) provided Pure Nickel exploration team with the ability to collect low-noise late time data under challenging conditions and identify electromagnetic anomalies at greater than  800 metres depth.

Dr. Mark Shore is going to represent example of using of lower frequencies induction coil, SQUID and fluxgate sensors on the nearest PDAC in Toronto:
