California Shaken: 4.2 Devastating magnitude earthquake rocks LA coast, waking residents abruptly

Brief summary of the recent 4.2 magnitude earthquake that occurred off the coast of Malibu

On Wednesday morning, Los Angeles was hit by a 4.2 magnitude earthquake off the coast of Malibu. Residents reported being awoken by the quake, with some describing it as feeling like a train going by. The earthquake struck at 2 a.m. and was located 28 miles southwest of Los Angeles and 10 miles south off the coast of Malibu. The United States Geological Survey reported at least four aftershocks of decreasing intensity. The National Weather Service reported that the quake struck at a depth of nine miles and no tsunami warning was issued.

The initial seismic event jolted the California coastline.

Aftershocks and Warnings

This earthquake comes a month after a fatal earthquake shook the north coast of California in late December. Two people died and more than a dozen were injured as a result of the 6.4 magnitude earthquake that occurred in the early hours of December 20th. There were also several aftershocks that resulted in homes being knocked off their foundations.

Previous Earthquakes in California and Nevada

California and Nevada are hit with an average of 25 earthquakes every year with magnitudes between 4.0 and 5.0, according to the Los Angeles Times. The Los Angeles Fire Department confirmed that they would enter ‘earth tremor mode’ following the recent earth tremor . A survey will be conducted from the ground, sea, and air to examine all major areas of concern such as transportation infrastructures, large places of assemblages, apartment buildings, and power-lines. Once the report is complete, the fire department will come out of ‘earth tremor mode’ assuming no major damage has occurred.

Why California sees so many Earthquakes

So why does California see so many earth tremor ? The west of the United States is prone to earth tremor due to the tectonic plates that lie underneath it. Tectonic plates are moving slabs that make up the outer layer of our planet and behave like conveyor belts in the way they carry and drag continents around on the surface. earth tremor typically occur at the boundaries of tectonic plates, where one plate dips below another, thrusts another upward or where plate edges scrape alongside each other.

Preparing for Earthquakes

California lies on top of the San Andreas Fault, which extends about 800 miles (1,300 km) through the United States, from the north of the Gulf of California through western California, before passing through the Pacific Ocean towards San Francisco. The fault was formed about 30 million years ago when the North American and Pacific plates began moving apart. This movement has resulted in the formation of the San Andreas Fault and the many earth tremors that occur in California.


In conclusion, earthquakes are a common occurrence in California and Nevada due to the tectonic plates that lie underneath it and the San Andreas Fault. While there were no immediate reports of damage or injuries following the recent earth tremor in Los Angeles, it serves as a reminder of the importance of being prepared for earthquakes and the potential for them to occur at any time.
