People in government offices, businesses and schools throughout Los Angeles County will stop everything for a minute Thursday to “drop, cover and hold on” during a statewide earthquake preparedness drill, now in its 13th year.
The Great California ShakeOut of 2021 is scheduled for 10:21 a.m.
“What we do to prepare now, before the next big earthquake, will determine how well we can survive and recover,” according to a statement posted to ShakeOut.org. “Great ShakeOut Earthquake drills are annual opportunities to learn and practice earthquake safety with millions of people.”
The ShakeOut website indicated that more than 7.5 million Californians are slated to participate in the drill. During last year’s event, which was virtual in most places because of the coronavirus public health lockdowns, about 6.5 million people statewide were registered to take part. The exercises began in 2008. According to the Shake Out website, nearly 2.364 million people are registered to participate in the drill in Los Angeles County.
The objective is to emphasize precautions during a 7.8-magnitude or larger quake along the southernmost portion of the San Andreas Fault. The U.S. Geological Survey says there is a 31% chance of a magnitude-7.5 earthquake or higher hitting L.A. in the next couple of decades.
Officials say such a tectonic shift could produce waves of movement for hundreds of miles, over four minutes. According to the USGS, some 2,000 people would die, tens of thousands would be injured and more than $200 billion in damage would result. The cataclysm would have 50 times the intensity of the Jan. 17, 1994, Northridge earthquake, which had a magnitude of 6.7.
Hundreds of aftershocks would ensue — a few of them nearly as big as the original quake, according to the USGS.
In 2019, the drill came just over three months after the early July quakes that struck Ridgecrest. The 6.4- and 7.1-magnitude shakers caused significant damage to roads and structures in the hamlet, which lies just south of the China Lake Naval Air Weapons Station.
Californians should be prepared to be self-sufficient for 72 hours following a major disaster. That includes having a first-aid kit, medications, food and enough water for each member of a household to drink one gallon per day, according to local and state officials. Homeowners and renters should also know how to turn off the gas in their residences in case of leaks.
The American Red Cross on Wednesday reminded people to find cover under a table or sturdy piece of furniture and hold on during an earthquake. It also clarified that using doorways as protection is a myth. People who are outside when an earthquake hits should stay away from buildings, power lines, trees and street lights, and drop to the ground until the shaking stops. Motorists should stay away from bridges, overpasses and power lines during an earthquake, and find a clear location to pull over.
California has a statewide earthquake early warning system that sends emergency alerts to people’s smartphones. People can receive alerts by downloading the MyShake App at https://apple.co/3CwyKQc for iPhones or https://bit.ly/2XAh2wa. Android users with updated operating systems automatically receive Android Earthquake Alerts using MyShake App’s technology.
