Data Event Response to the 10 June 2016 Mw 5.2 Earthquake 20km NNW of Borrego Springs, California

Written by David Phillips & Beth Bartel
13 June 2016

Tectonic Summary

This event occurred within the San Jacinto Fault Zone, between the Elsinore Fault Zone to the west and the San Andreas Fault Zone to the east. While the San Andreas marks the actual boundary between the Pacific and North American plates, the Anza-Borrego region is caught up in the wide zone accomomodating the strike-slip motion.

For more information on this event, see the USGS Earthquake Hazards Program event page.

UNAVCO Response

High-Rate GPS Data
In response to the Mw 5.2 Earthquake 20km NNW of Borrego Springs, California on 2016-06-10 12:09:02 (UTC), UNAVCO is downloading high-rate five-sample-per-second (5-sps or 5 Hz) GPS data from PBO stations within 80 km of the epicenter for a 7-day period around the event (day of event ± 3 days). A map of GPS stations being downloaded is shown in Figure 2. These data will be available from ftp://data-out.unavco.org/pub/highrate.

GPS Velocities
The GAGE GPS Analysis Center Coordinator estimates coseismic offsets for any stations that experience horizontal displacements of > 1mm. If such offsets are observed, station offset files will be made available from ftp://data-out.unavco.org/pub/products/event/.

Borehole Strainmeter Data
A fully processed 1-sps borehole strainmeter (BSM) dataset spanning the time period of this event is now available at http://borehole.unavco.org/bsm/earthquakes/
, also linked from the UNAVCO borehole Geophysical Event Data page.
