On Monday, September 16, another earthquake struck Southern California – the second in less than five days.

On Thursday, September 12, an earthquake centered in Malibu shook most of Los Angeles County. The residents were woken from their sleep at around 7:30 a.m. local time. Many were immediately amazed at the extent of the shock. While earthquakes are not uncommon in LA, recent tremors over the years have increased fear locally.

Here you will find everything you need to know about the earthquakes and aftershocks.

How strong were the LA earthquakes?

Monday, September 16th — A preliminary magnitude 3.6 earthquake struck in the Malibu area at a depth of nearly seven miles around 4:22 a.m. Pacific time, according to the U.S. Geological Survey. No injuries or damage were initially reported.

Thursday, September 12th — According to the US Geological Survey, the September 12 earthquake had a magnitude of 4.7. NBC Los Angeles reported that the initial brightness was measured at 5.1, but was later downgraded to 4.7. No damage to infrastructure or major injuries were reported at the time of publication.

The California Geological Survey's X report confirmed the quake. The tweet said: “An M4.7 earthquake just occurred near the coast of Malibu [sic]. Moderate shaking was felt near the epicenter and in western Los Angeles. Aftershocks are to be expected.”

According to KTLA, the California Highway Patrol (CHP) reported that some boulders and rocks rolled onto Malibu Canyon Road in a tunnel near Piuma Road. This was the epicenter. In the morning, officers began removing rocks from the crime scene.

Was there an aftershock of the LA earthquake?

Monday, September 16th – KTLAs Eric Spillman commented on the quake Monday morning, saying, “It may be an aftershock of the quake we had a few days ago.” He noted that the station's studio on Sunset Boulevard in Hollywood did not feel the tremors. However, the USGS report states “Did You Feel It?” On the map, the quake was felt as far away as Long Beach in the southeast and Ventura in the northwest.

Thursday, September 12th – Several small aftershocks were reported after Thursday's quake, including one with a magnitude of 2.8 that occurred just two minutes after the first earthquake at the Malibu epicenter. Officials warned residents of Malibu, Hermosa Beach, Anaheim, Santa Monica and surrounding areas to expect more aftershocks in the coming days.

What should you do in case of an earthquake?

During an earthquake, experts emphasize the importance of knowing the proper steps to take to protect yourself and minimize injuries. The California Department of Public Health (CDPH) provides detailed guidelines on what to do at these events. Here are some important steps you should take in the event of an earthquake:

  • Put down, cover and hold on: Fall to your hands and knees to prevent yourself from being knocked over. Cover your head and neck (or your entire body if possible) to protect yourself from falling debris. If you're indoors, take cover under a sturdy piece of furniture like a table or desk. Hold on until the shaking stops.
  • Stay inside: If you're inside, stay there. Do not run outside while shaking as falling debris could injure you. Stay away from windows, glass and other objects that could break.
  • When you're outside: Move away from buildings, street lights and utility cables. Fall to the floor and cover your head and neck.
  • When you are in a vehicle: Drive to a safe place, away from overpasses, bridges and large trees. Stay in the vehicle with your seat belt fastened until the shaking stops.
  • After the shaking stops: Be wary of possible aftershocks that may follow the mainshock. Check yourself and others for injuries and provide first aid if necessary. Avoid using elevators and be aware of possible hazards such as gas leaks or damaged electrical cables.
  • Follow emergency instructions: Listen to local news or emergency services for updates and instructions.
