On 4th of July 2019 Ridgecrest, CA was struck by a 6.4 magnitude earthquake. Initially it was believed to be the main earthquake, but on July 5th, the same region was struck by a magnitude 7.1 earthquake, the largest the region has seen in 20 years. The shaking could be felt from San Diego to Las Vegas where a basketball game was stopped due to the shaking. There were reports of about 50 damaged building in the small town of Trona, CA, and damaged roads and rock slides both in Rdgecrest and surrounding areas.
According to Dr. Lucy Jones of Cal Tech and the US Geological Survey, this is the normal for the region. Apparently, there is supposed to be at least one earthquake above a 6.0 magnitude every 3-5 years in the region and the fact that this 7.1 took 20 years is odd. Seismologists also stated that there is an increased chance of an earthquake larger than a 6.0 magnitude occurring in the next few days (a 27% chance) and there is only a 3% chance of there being an earthquake larger than a 7.0 magnitude.
California and Nevada residents are encouraged to prepare in the event of a large earthquake with earthquake kits, action plans, and outside communication. Kits should include bottled water, canned food, flashlights, batteries, and portable chargers, etc. There should also be an action plan and a plan of communication. The action plan should include designated meeting points with friends or family in case you are not together when the earthquake strikes. Communication plans should include a person who is outside of the region in the event that local phone lines are over crowded and you can not get through to your loved ones.
While the event of a large earthquake is unlikely in the coming day, this does not mean it is never going to happen. It's only a matter of time, so be prepared!
