Seismicity in 3D

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).

EGS: About Desert Peak and Brady's Hot Springs

Brady’s Hot Springs is one of two existing producing geothermal fields (along with Desert Peak, a few miles south of Brady’s) in a sparsely populated region of Northern Nevada. Located in the “Basin and Range” extensional geologic province, this field is a small producer (less than 15 MW) compared to such fields as The Geysers in Northern California, but it is a site of interest as an EGS project.

EGS experiments were carried out by the operators (Ormat Inc ) and  DOE  in 2010 and 2011 to determine the potential for expanding the production of geothermal energy. In early 2010, an array of 8 shallow (100 ft) borehole three-component stations (similar to that at Desert Peak) was installed at Brady’s Hot Springs to monitor seismic activity prior to EGS activity at the Brady's site. Seismicity prior to injection at Brady’s was very low, similar to seismicity at the Desert Peak site. Note that the detection threshold of each array is about a magnitude -1.0. The detection threshold of the regional network in this area (operated by the University of Nevada, Reno) is on the order of magnitude 1.0 to 1.5.
