The July 2019 Ridgecrest earthquakes in southeastern California were characterized as surprising by some, because only ∼ 35 % of the rupture occurred on previously mapped faults. Google searches in California for San Andreas spiked during the Ridgecrest quakes and the Mexico earthquakes of September 2017. RIDGECREST, CALIFORNIA - JULY 04: A local resident inspects a crack in the earth after a 6.4 magnitude earthquake struck the area on July 4, 2019 near Ridgecrest, California. Fault Zone, oriented roughly NW-SE This was an M7.1 on a fault orthogonal (rotated 90 degrees) to the strike of the M6.4 and was also a shallow strike-slip event. 2019/07/08 ET . A strong 6.4 magnitude earthquake struck Southern California on Thursday, centered in a remote desert area some 150 miles northeast of … earthquake sequence.

About 34 hours later (at 8:19pm local time) and 11km (6.8 mi) NW of the M6.4 event, another larger earthquake occurred. Depth is referenced to a surface elevation of 0.7 km above sea level. collected ascending ScanSAR data for track 065 Bridget Smith-Konter2, We studied the 2019 Mw6.4 and Mw7.1 Ridgecrest, California, earthquake sequence, using Sentinel‐1 and ALOS‐2 coseismic interferograms and subpixel offsets to retrieve the three‐dimensional (3‐D) surface displacements.By inverting the 3‐D displacements, optimal dip angles of the earthquake faults and the slip model were obtained.

Bottom left: USGS Seismologists Alan Yong and Elizabeth Cohcran conduct field work near the main rupture between Trona and Ridgecrest California. Phase   - note the MAI interferogram need to be A new study of the Ridgecrest Earthquake Sequence, the largest earthquake sequence in Southern California, that began on July 4, 2019, provided new evidence that massive earthquakes can happen in a more complex fashion than commonly expected.

The July 2019 Ridgecrest Earthquakes were California's biggest in more than 20 years. The Data from seismic sensors in buildings across Southern California show how the 7.1 Ridgecrest earthquake produced surprisingly long periods of shaking in some areas. For the Analysis of recent Ridgecrest, California earthquake sequence reveals complex, damaging fault systems.
