Observational Studies of Induced Earthquakes
In response to sudden changes in seismicity that are potentially induced by human activity, the USGS may deploy temporary seismic stations to better understand the earthquakes. These deployments typically consist of 2-15 seismometers placed in the immediate vicinity of the seismicity.
