3D Seismic Distribution

The 3D scatterplot below shows the selection of earthquakes satisfying the filter criteria above. You can use your mouse to click on the map and rotate it and zoom in or out. Clicking on the bottom right corner of the plot will allow you to resize the window. The units of depth are kilometers and 0.0km is sea level.

Please note: The 3D visualization provided below is implemented using the canvasXpress library, which employs the html5 canvas element in order to simulate 3D without any special download or plugin. It will only work on the latest, most current browsers. If you are having problems viewing the plot and have an older browser, we highly recommend either upgrading your browser, or installing the latest version of a different browser (e.g., Mozilla Firefox or Google Chrome).

About the Geysers

The Geysers Geothermal Field in Northern California is the largest single geothermal field in the world (over 800 MW in 2009 and increasing as EGS activities carry forward). Seismicity related to production and injection has been observed since the 1970s and has been used as a general indicator of fluid paths and reservoir response. An increase in injection rates using wastewater from the areas of Santa Rosa and Lake County, CA, has recently raised concerns regarding the impact of injection-related seismicity on nearby communities.
