Induced Seismicity Monitoring

Case studies

Geobit, May 2021

1. Introduction

GEObit P.C. supplied ISTI USA [1] with several C100/GEOthree[2] sensor/datalogger units, to be used in a new induced seismicity monitoring project in the USA. The network and the customer are confidential, therefore only limited information can be posted here.

2. Seismic Stations

The GEObit hardware, the battery, the battery charge controller, and the GSM router are housed into metallic boxes, custom made for the project. The stations were tested before deployment. The sensors were placed into boreholes for achieving better signal to noise ratio.

3. Seismic Network

Several seismic stations were installed in the field, and they are still in operation. The stations are monitoring induced earthquakes as well as natural seismicity of the area.

4. Installation

The seismic stations are getting power from two 90W solar panels. Overall power consumption is very low thus allowing the use of two solar panels and a single battery, which is enough to power the seismic equipment and the GSM router for over one week, if there is no solar charging. This may happen during wintertime.
