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 & Geobit join together at the AGU Annual Meeting in Washington, D.C. 10 – 14 Dec. 2018. We are a team providing a complete seismic monitoring solution. Contact us through EarthImaging.com.
With 65+ years of combined experience, GEObit and ISTI are joining forces to become the most competitive and fastest growing joint venture group in the seismic monitoring services industry.
Providing state-of-the-art seismic instruments, network design, installation techniques, data monitoring and processing services, our group is able to deliver a cost-effective total solution to the energy exploration & production industry, especially to the oil, gas and geothermal sector. Our key benefits are that we produce in-house hardware and software while installing and maintaining the microseismic monitoring network to ensure a high level of data quality and availability. In other words, we make the technology – we apply the technology – we offer the technology.

We have worldwide experience having installed and operated seismic networks all over the world, from Indonesia/Papua jungle to the Middle East desert, from Alaska glaciers to Himalayan Mountains. In the USA, we are currently running many dedicated microseismic monitoring projects with over 200 stations installed in the past 10 years.
Visit us at booth #815, AGU 2018
Washington, D.C. USA | 10 – 14 December
Meet our team and learn about the latest offerings. Dimitris Mourtzouchos & Nikos Germenis (Geobit), Paul Friberg & Sid Hellman (ISTI), and others will be available to answer your questions. Continue reading
Stop by and chat with Sid Hellman and Matthias Auer of ISTI this week at WOSMIP.
ISTI is pleased announce that Matthias Auer of ISTI will be presenting The STAX Project – Data Processing infrastructure on Thursday, 6 December, at 11:10am in Sydney, Australia.
Instrumental Software Technologies, Inc. is a proud sponsor of the 2018 Workshop on Signatures of Man-Made Isotope Production (WOSMIP).
Friend of ISTI, Geobit is exhibiting this year at RAUGM 2018 in Puerto Vallarta, Jalisco, Mexico, from October 28 to November 2 in cooperation with it’s local distributor Geoelec.
GEObit provides high sensitivity wide-band and near broad-band seismic sensors, surface or borehole type, and high dynamic range, low power 32bit ADC data loggers with local data storage and real-time telemetry over seedlink protocol. We are focusing on low power and cost-efficient solutions so we provide to our customer seismic networks with low installation and maintenance costs. Our instruments are ideal for local and regional seismicity and micro-seismicity monitoring and for seismic events such as those induced by unconventional hydrocarbon extraction. Our high fidelity data loggers ensure that these signals are recorded with the highest resolution and timing accuracy.
Visit them at booth #E4
Meet their team and learn about their new upcoming instruments and technologies. They will also be available to answer your questions.

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.
Both Ben Baker of ISTI and GFAST were highlighted in El Mercurio newspaper on 6 February 2018 in the Chile aplicara sistema para agilizar alerta temprana de maremotos y terremotos article (loosely translated, Chile will apply system to streamline early warning of tsunamis and earthquakes).
An inherent difficulty in seismic-only earthquake early warning and tsunami forecasting is the rapid estimation of the earthquake magnitude and description of the rupture. One novel approach is to augment the seismic-base system with geodetic information that can better capture the static-offset produced during large events. In conjunction with the University of Washington, the Amazon Catalyst program, and the Centro Sismológico Nacional, ISTI is helping to make the Geodetic First Approximation of Size and Timing (G-FAST) production ready in the dynamic Chilean tectonic setting. It is expected that the G-FAST enhanced Earthworm+Earlybird base system will be able to better characterize the frequent high-magnitude events on the Chilean subduction zone and ultimately improve rapid shaking and tsunami inundation estimates.
ISTI is pleased to announce a publication of G‐FAST Earthquake Early Warning Potential for Great Earthquakes in Chile, a collaboration between Ben Baker of ISTI and our colleagues in the field.

Recent studies have focused on how wastewater disposal wells have caused dramatic increases in eastern US earthquakes. We focused instead on less common cases where hydraulic fracturing alone has caused earthquakes and found seismicity separated into two depth zones: a shallow zone on younger faults, with more small-magnitude earthquakes than expected, and a deeper zone on older faults, with larger magnitude earthquakes and seismicity continuing after fracturing stops. Hence, inducing deeper seismicity creates more hazard. Our observations are consistent with prior geologic, laboratory, and theoretical work indicating that age and maturity of faults causes the different seismicity patterns. We utilize data from well operators to demonstrate that both fluid pressure changes and rock stress transfer are needed to explain our observations.
Understanding the causes of human-induced earthquakes is paramount to reducing societal risk. We investigated five cases of seismicity associated with hydraulic fracturing (HF) in Ohio since 2013 that, because of their isolation from other injection activities, provide an ideal setting for studying the relations between high-pressure injection and earthquakes. Our analysis revealed two distinct groups: continue reading.
