Seismic Monitoring Sites

We are planning to turn on the stimulation pumps later this week.  Then we expect our instruments will pick up tiny seismic events which indicate that the injected water is finding and creating pathways away from the well. There are two websites that you can use to see what is happening.

First, the EGS Induced Seismicity Monitoring site at Lawrence Berkeley  National Lab shows the seismicity recorded by all 15 of the seismometers that we installed.  The LBNL site includes a 3D viewer of the geothermal well and microseismicity resulting from water injection.

Second, the Pacific NW Seismic Network, based at the University of Washington in Seattle, has 20 seismometers south of Bend, Oregon, including five that we installed.  This is part of a USGS program to monitor seismicity at all the Cascade Volcanoes.  Notice that  compared to Mount Rainier, Mount St. Helen’s and Mount Hood, Newberry is quiet, but PNSN is forecasting small quakes near Newberry.  I wonder why?
