A stronger type shaking was felt across Southern California, especially Inland, on Friday morning. Will there be more and what to expect over the next 24 to 48 hours. Evidence does suggest that some faults can trigger nearby faults in a short amount of time so keep to your earthquake precautions over the next week.
The earthquake was between a 5.0 and 5.2 magnitude. There were two back to back earthquakes detected, however close monitoring of the area’s waveforms may seem that it was just one earthquake and the instruments were confused on triangulating the location so it put two nearly identical earthquakes there.
The earthquake was centered around or on the San Jacinto Fault. The depth of 21km suggests the quake was shallow, a reason for the violent shaking in some areas near the epicenter. It was felt as far away as the High Desert, Six Flags Magic Mountain, Orange County, San Diego, and the Colorado River Valley.
Over the next 12 to 24 hours you can expect many aftershocks, some of equal size. However as every 3 hours pass from the mainshock … the chances of a larger one diminish. Aftershocks will continue for many days to come.
Other fault-zones could have been affected by this. Evidence does suggest that some faults can trigger nearby faults in a short amount of time so keep to your earthquake precautions over the next week.
