Yehuda Bock and the rest of SOPAC have also been busy since the Ridgecrest Earthquakes shook So Cal. SOPAC computed coseismic offsets for the two events using the GAMIT/GLOBK software with 30s data from 109 continuous GNSS (Global Navigation Satellite Systems) stations within a radius of 160 km from the epicentral region.

Frank Vernon also spoke to reporters from the Times of San Diego about the recent EQs. The article "Recent Back-to-Back Earthquakes Don’t Signal ‘The Big One’" should reassure readers that the seismic activity in Ridgecrest is very unlikely to have any impact on the San Andreas fault. The full article is available here.
IGPP Research Geophysist Frank Vernon can be heard here on KPBS's Midday Edition discussing the July 4th (M6.4) and 5th (M7.1) Earthquakes near Ridgecrest. Vernon discusses the unusual strucure of the faultlines and their relation to other known faults.
Debi Kilb and her collaborators share an annoted NASA satellite graphic to commence a thoughtful article about the unique Ridgecrest fractured fault lines as well as how the quakes have had a catalyst-like seismic effect in the region.
Debi Kilb met with news crews again today. Reporters from KGTV Channel 10 contacted Kilb to learn more about the remarkable seismic activity over the past 48 hours. In her interview, Kilb spoke about the high magnitude (M6.4 and M7.1) and time between quakes (< 36 hours) and said these two factors indicate the quakes were neaither foreshocks nor aftershocks, but rather mainshocks she describes as an Earthquake Doublet. Kilb also discussed the unique right lateral motion of the—until now—unknown faultline.
