As noted in the Houston Chronical news article, a new study published this week in Geophysical Research Letters indicates that much of the recent seismicity in the Eagle Ford shale gas play in Texas is induced by hydraulic fracturing. Fasola and her colleagues found a significant correlation between completion activity on wells and earthquakes close by. They further noted a large increase in seismicity that was coincident with the operations that was over 30 times the background seismicity rate for the area in 2018. The state seismic network, TexNet, provides earthquake locations to operators and the public during business day operations, but if operators need rapid and more timely access to data, ISTI provides a Rapid Notification Service from our cloud system that is operating 24×7. Get notified of an earthquake in your area of operation as it unfolds.
If more stations are necessary, ISTI provides rental equipment and crews to deploy stations at a moments notice. We also have professional seismologists to help with regulatory issues related to seismicity. Contact us today to see how we can apply our analytics and experience to your operation’s seismicity issues.
ISTI is pleased to share the “Radioxenon net count calculations revisited” article from the Journal of Radioanalytical and Nuclear Chemistry, featuring Matthias Auer of ISTI as second author.
Since 1998, there have been improvements in the capability to detect atmospheric radioxenon in the International Monitoring System operated by the Preparatory Commission of the Comprehensive Nuclear-Test-Ban Treaty Organization. The upgrades have resulted in next-generation versions of the radioxenon systems. This paper explores radioxenon data analysis
improvements beyond the original radioxenon beta–gamma analysis equations that were formulated in 2000 . . . read more here.
ISTI presents, participates and sponsors the 2019 Science And Technology Conference in Vienna Austria this week, June 24 to 28, 2019. ISTI’s Sid Hellman, Matthias Auer, and Josh Stachnik are all at the meeting and looking forward to discussing our work with you. Visit ISTI at Booth #3 in the exhibit space and please come and see our poster on Wednesday T3.5 poster 67 on our Radionuclide work:

ISTI’s Paul Friberg will be presenting his and his colleagues research on “Hydraulic Fracture Induced earthquakes in Ohio” at the ARMA sponsored workshop on Induced Seismicity on Sunday June 23, 2019.
ISTI’s Sid Hellman is attending the annual EarthCube meeting this week in Denver, Colorado. Please stop by and say hi to Sid and ask about the web development work we did for this cool NSF funded project. You can see more about the program at this link for the schedule.
Sid Hellman of ISTI welcomes attendees to visit him at the 6th ACM-W New York Celebration of Women in Computing, April 12-13, 2019, at the Fort William Henry Hotel and Conference Center in Lake George, NY.
With over 20 years’ experience in scientific software, Sid will be available to share his expertise.

2019 Earthworm Course in New Paltz, NY, June 3 – 7
This 3 – 7 June, ISTI will host another of our popular Earthworm training courses in New Paltz, New York. This will be our traditional 5-day course. Our full ad may be found here.
We ask that interested students — and any colleagues who wish to join —
ISTI CEO and Founder, Paul Friberg teaching EW students. Photographer, ISTI Staff
- Archiving and Playback of data
- Data exchange
- Visualization tools
- Overview of various non-Earthworm post-processing options
- Tuning for Earthquake Location and Magnitudes
- Programming new modules, learning APIs
In addition, we will provide a tuning session for anyone that wants to bring their network’s Earthworm configuration to the course. We will show you how to playback your data and tune the earthquake location engine.
This course will be useful to anyone setting up, managing, tuning, or developing for an Earthworm system. See full class details here (inc. location, transportation, etc.).
Again, if you plan to join the Spring ISTI EW 5-day class,
Thank you in advance for your confirmation of attendance.
ISTI is pleased to announce that Comparison of Detection and Location Capabilities of Surface Microseismic Monitoring Algorithms, by ISTI authors, will be presented at the European Geosciences Union General Assembly, being held in Vienna, Austria on 8–13 April 2018.

The challenge of the surface microseismic monitoring (MSM) is that small-scale seismic activity which occurs as a result of human activities or industrial processes is often hidden in surface noise on individual seismic records. MSM algorithms must detect and locate signals with average signal-to-noise ratio (SNR) significantly less than 1. To improve SNR MSM algorithms compute cost function over a large set of seismic records. Maximum of such function indicates presence, time, and location of the seismic signal. Other algorithms, such as Phase Robust Statistically Optimal and Diagonal Maximum Likelihood Adaptive algorithms offer accuracy improvements of location and detection in presence of correlated industrial noise. In this paper we use synthetic seismograms and seismic observation to compare accuracy of event locations using several algorithms of surface microseismic monitoring.
ISTI is a proud sponsor of the Vienna (Austria) Chapter of the Institute of Nuclear Materials Management’s annual STEM fair to be held at the Vienna International School on Saturday April 21, 2018. ISTI invites you to come on by and see the great work being done in the STEM fields by the next generation of bright minds.
