Data Sets for Mw 7.1 Ridgecrest Sequence

The SCEDC has the following links and data sets for use by the research community studying this event. The SCEDC is also archiving and distributing waveform data from portable stations installed by the USGS shortly after the event. Yellow triangles denote seismic stations; CI network stations are outlined in red, and partner permanent and portable stations are outlined in black.

Data available through webservices or STP, or the SCEDC AWS Dataset (Includes DAS dataset).

NOTE: The east and vertical channel names for the ZY data are swapped. This is reflected in the metadata as of April 15, 2020.

Map from Hauksson et. al (2019) showing the Mw 6.4 foreshock and Mw 7.1 mainshock (stars) and their ∼40,000 aftershocks and three off‐fault clusters near the Garlock fault, Panamint Valley (black dots) and near the southern terminus of the 1872 M 7.5 earthquake (red lines at top of map). First‐motion and S/P‐based focal mechanisms for the Mw≥5 events are also included labeled with month, day, hour, minute, and magnitude. The 2019 surface rupture (red lines) is from Kendrick et al. (2019). Late Quaternary faults (brown lines) are from Jennings and Bryant (2010). Yellow triangles denote seismic stations; CI network stations are outlined in red, and partner permanent and portable stations are outlined in black. The main highways, 14, 178, and 395 are shown as purple lines; Coso geothermal area and nearby cities, including Ridgecrest and Trona, are shown as green squares; and the boundary of Naval Air Weapons Station China Lake is shown in blue.
