#Elvui update 7.1 series
Scientists from the USGS and other organizations continue field work and analyses to learn more about the series of earthquakes and aftershocks centered in the Southern California desert near Ridgecrest. Updated on July 12. Visit the USGS earthquake event page for more information. This forecast takes into account the behavior of past sequences in similar tectonic environments and the aftershock sequence observed for this event so far. The chance of a magnitude 3 or higher earthquake is 99% during the next week.
The odds of a subsequent large earthquake continue to drop with time since the mainshock. As of July 18, there is a 1 in 300 chance of a magnitude 7 or greater aftershock, a 3% chance of a magnitude 6 or greater aftershock and a 29% chance of a magnitude 5 aftershock in the next week. Circles indicate where scientists have visited the fault surface rupture. (Credit: USGS. Ruptures from the magnitude 6.4 event trend northeast to southwest, and ruptures from the magnitude 7.1 event trend northwest to southeast. General surface rupture based on field mapping and satellite data as of July 15, 2019.
