In 2014 ISTI worked closely with AltaRock Energy on monitoring the seismicity surrounding a stimulation test at the Enhanced Geothermal Field at the Newberry caldera in Oregon. ISTI configured and helps to manage an Earthworm system for detection and auto location of earthquakes for AltaRock for this project. A nice news article on the Newberry development is available at Renewable Energy World website. ISTI will be working with AltaRock on monitoring seismicity at other geothermal energy development projects in the near future.
Earthworm just made a few headlines again in a recent article in the Bulletin of the Seismological Society of America (BSSA) electronic early release. The central weather bureau in Taiwan has been using Earthworm for some time now, and for earthquake early warning work for the last two years. Our friend and colleague Dayi Chen just published the article on the Earthworm based system. It is titled and linked to below
As always, ISTI will be at the AGU fall meeting. You can find us booth 1823 where we will be showing off some new Tsunami monitoring software we are involved with developing. We are still heavily involved in 3 areas of geophysics:
- Nuclear explosion monitoring,
- General geophysical software development using Open Source tools and packages include Earthworm, and
- Geophysical science services for earthquake and other waveform-based technologies
Please stop by and chat with us about our projects in monitoring Geothermal, Oil and Gas fields, Injection Wells, Hydraulic Fracture stimulation projects, or other induced seismicity concerns. See how ISTI’s expert staff can help you solve your geophysical problems and establish a long term relationship with our company that is now in its 16th year of operations.
Please come and meet some of our newest seismologists (Ben, Mike, and Josh) and the usual suspects of Paul, Sid, and Stefan.
ISTI’s Paul Friberg will be attending the USGS and Oklahoma Geological Survey’s hazard from Induced Seismicity workshop in Midwest City Oklahoma next week (Tuesday November 18, 2014). Contact Paul if you wish to discuss monitoring of Induced Seismicity or any of the earthquake science services that ISTI provides.
ISTI’s Paul Friberg will be presenting at the SEG Post-Workshop meeting on Induced Seismicity as an invited speaker. This is following on the release of our Seismological Research Letters (SRL) paper on Hydraulic Fracture induced earthquakes in Ohio, and our presentation at the Banff Injection Induced Seismicity Meeting in September 2014. The SRL paper was widely reported on by the media the week of October 15, 2014 when the Seismological Society of America did an early on-line release.
ISTI is presenting some of the science behind monitoring injection wells for possible induced events at the Society for Exploration Geophysicists (SEG) workshop on Injection Induced Seismicity this week (Sept 15 to 18) in Banff, Alberta, Canada. Injection induced earthquakes have been attributed mostly to waste water injection wells, but also to Geothermal applications, and hydraulic fracturing. ISTI’s Paul Friberg is presenting on Tuesday some of the results of his research in Ohio on positive magnitude hydraulic fracture induced earthquakes.
SeisNetWatch, the widely used seismic network state of health (SOH) monitoring tool, can now connect to Nanometrics Centaur and Taurus dataloggers to obtain all state of health information for processing. Any SOH parameter provided by these dataloggers can now be pushed through the SNW system for health determination. Contact us if you use this equipment and need a single control panel to view the SOH of any seismic equipment.
The ISTI development for the MUSTANG State of Health (SOH) metrics system and the LASSO presentation tool were recently highlighted in the IRIS DMC newsletter. The newsletter is published quarterly and highlights projects of importance at the IRIS Data Management Center. MUSTANG and LASSO are new tools for monitoring the SOH of broadband sensor networks that IRIS archives. The news letter of interest mentioning ISTI is the Volume 16 Number 2 for the Summer of 2014.
ISTI’s Paul Friberg presented a paper on induced seismicity at the recent Seismological Society of America meeting in Anchorage, Alaska. The research focused on a case of induced seismicity from a hydraulic fracture operation in Ohio, the site of nascent regulation by the state regulatory agency. A well operator most probably intersected a high permeability pathway that allowed pore pressure changes to reach a tectonic fault in the basement, triggering a cluster of magnitude 2 earthquakes.
This June 2 through June 6 ISTI will host another of our popular Earthworm training courses. Earthworm is the most popular open source earthquake data acquisition and location processing system. Originally developed by the USGS, it is now maintained and moved forward by a group of developers that ISTI organizes.
The basic course will cover:
- Configuration tips,
- Archiving and Playback of data,
- Data exchange,
- Visualization tools and post-processing with SEISAN,
- Tuning for Earthquake Location and Magnitudes and
- Programming new modules
In addition, new for this version of the course, 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.
The course will be taught by Paul Friberg and Stefan Lisowski who have a combined experience with Earthworm of over 24 years!

Contact ISTI for availability as the course is limited to 12 participants.
