Structural Health Monitoring

STRUCTURAL HEALTH MONITORING WORKS.

“Monitoring building behavior upon earthquake impact.”

Seismic monitoring systems provide critical data on building behavior during earthquakes, improve understanding of structural stability, and lead to better building codes. Additional benefits include reduced inspection time after large earthquakes, since onsite visits by engineers may not be necessary when enough data are available. Our systems help satisfy common government requirements for seismic instrumentation when monitoring earthquakes in critical or large buildings. Continue reading

ISTI Now Offers AQMS, a Software Installation and Support Service, in a Postgres Version

For further information, reference the Seismological Research Letters article “Open-Source ANSS Quake Monitoring System Software”.

Abstract

ANSS stands for the Advanced National Seismic System of the U.S.A., and ANSS Quake Monitoring System (AQMS) is the earthquake management system (EMS) that most of its member regional seismic networks (RSNs) use. AQMS is based on Earthworm, but instead of storing files on disk, it uses a relational database with replication capability to store pick, amplitude, waveform, and event parameters. Continue reading

Oklahoma Drill Completion Stopped Following Earthquakes

“Oil and gas producer Encana Corp halted work at a drill site in northwest Oklahoma following two earthquakes within a day in the same area,” according to Thursday’s Financial Post article.  Early detection is a service that we pride ourselves on at ISTI.  According to the article, “several years ago, Oklahoma suffered a spike in earthquakes that authorities tied to the underground disposal of saltwater.”  Local authorities cracked down in 2018, announcing new seismic requirements and penalties for companies who do not meet the requirements.  Non-compliance risks costly business halting and shut down, and now early detection is as important for businesses and communities as ever.  

 
ISTI’s cutting edge software, coupled with GEObit state-of-the-art equipment, provides a complete solution.

ISTI: the proud official U.S. distributor of GEObit instruments

ISTI is the proud official U.S. distributor of GEObit instruments.

The GEObit Equipment Plus ISTI Software Equals a Complete SolutionS-20 seismometer is a three-component velocity output near broad band seismic sensor. The design is based on the electronic velocity feedback which is applied to single coil low period geophone. The frequency bandwidth is extended from 50Hz, down to 20sec.

ISTI et. al “Radioxenon net count calculations revisited” article

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.

Abstract

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.
