How do earthquakes shake California?
Magnitude: 4.6 Southern California is shook by the Malibu earthquake, both inland and along the coast.
There have been reports of shaking all throughout the place, including the South Bay, Riverside and Orange counties, the San Fernando Valley, the ocean, and downtown Los Angeles
Early on Friday afternoon, Southern California experienced extensive shaking from the coast to interior areas due to an earthquake with a magnitude of 4.6, located northwest of Malibu.
In the Santa Monica Mountains, roughly seven miles northwest of Malibu, an earthquake was detected shortly before 2:00 p.m. Within an hour, more than a dozen aftershocks were recorded in the same area, the greatest of which had magnitudes of 3.0 and 2.7.
According to seismologist Dr. Lucy Jones, “it’s got a very robust aftershock sequence,” and the likelihood that the earthquake was a precursor to a more significant seismic event gradually fades.
Up to 12 mil lion people in the greater Los Angeles area may have reported experiencing shaking. The San Fernando Valley, downtown Los Angeles, Riverside, Irvine, and Anaheim were among the inland locations affected by the earthquake, as well as the coasts of LA, Orange, and Long Beach and the South Bay are included in the Ventura counties.
Some areas of north San Diego County also experienced mild to moderate shaking.
“It was quite startling,” Dailey remarked. “We all realized what was happening. The patients carried on with their dental, unharmed. It’s a little unsettling every time.”
No initial reports of notable damage were received .he Los Angeles Fire Department had a standard procedure for assessing damage after a larger-magnitude earthquake..
No tsunami was set off, according to the US National Tsunami Warning Center.
When Marla Dailey started to tremble, she was working in a Thousand Oaks dentist office. Although there are several earthquake faults in the region, Jones speculated that the quake may have originated on the Malibu Coast Fault, which traces the Santa Monica Mountains’ shoreline.
The Pacific Palisades, Westwood, Beverly Hills, and Santa Monica areas are close to the fault. The Santa Monica Fault meets it at its eastern end.
On the same day as the earthquake, the devastating magnitude-6.5 San Fernando earthquake of 1971 also takes place. Dozens of people died as a result of that historic earthquake, which also damaged more than $500 million worth of property and sparked concerns about the possibility of a disastrous dam collapse. Although it originated in the San Gabriel Mountains’ foothills to the north of Los Angeles, the entire San Fernando Valley was shaken.
On Friday, an earthquake with a magnitude of 5.7 struck Hawaii’s Big Island, causing tremors to be felt 200 miles distant on Oahu, including in Honolulu. There was nothing seismically related to that quake in Southern California.
