A magnitude 3.2 earthquake struck a few miles south of Malibu on Wednesday, causing a light shaking of the coastal city.

According to a crowdsourcing website submitted to the U.S. Geological Survey, the earthquake struck the weaker vibrations in the West Side of Los Angeles at 9:33 a.m. The center is about 2.7 miles southwest of Malibu Point.

Offshore Temblor appeared just three weeks after the magnitude 5.2 earthquake, to eastern San Diego County, rumbled in southern Southern California - breaking bottles, wine glasses and pottery, but causing minimal damage.

Over the past 16 months, Wednesday's earthquake also added a series of seismic activity in and around the Malibu region.

Recent famous temborres include the magnitude 4.6 earthquake on February 9, 2024; the magnitude 4.7 earthquake on September 12, 2024; and the magnitude 4.1 earthquake on March 9.

But while everything is relatively modest and has little harm caused, they are an uneasy reminder that there has been no major earthquake in Los Angeles and Orange counties for a long time.

Since 1998, in this densely populated county, there has been only one earthquake of 5 or more. This was a magnitude 5.1 earthquake centered on Brea in 2014, where Fullerton and La Habra caused more than $2.5 million in losses.

There was also a magnitude of 5.4 in the 2008 Chino Hills earthquake. Centered on San Bernardino County, but only east of Los Angeles and Orange County, there was little damage.

It has been 31 years since the June 7 North Mountain earthquake hit Los Angeles, more than 35 years since the June 9 Loma Prieta earthquake, and Santa Cruz County ruptured, causing extensive damage throughout the San Francisco Bay area.

In this relative earthquake drought, some communities have recently taken action to improve earthquake safety.

Last December, Burbank City Council unanimously approved a mandatory renovation ordinance for apartment buildings, a statute with a fragile first floor known as a "soft story" that could collapse in an earthquake. Well-known design flaws are often the result of a ground-floor carport or a garage with thin columns supported on the first floor, which can collapse when the first floor shakes left and right.

The law came into effect on January 19, affecting wooden framed buildings on at least two floors and is built using building code standards established before 1978. Burbank law requires renovations to be completed by 2030.

Burbank offers a refund of the building permit fee to owners who have completed the renovation earlier.

More than six cities in Southern California have chosen to remodel work on soft apartment buildings – Los Angeles, Torrance, Pasadena, Pasadena, Santa Monica, Culver City, West Hollywood and Beverly Hills. In Northern California, the list includes San Jose, San Francisco, Oakland, Fremont, Berkeley, Albany and Mill Valley.

However, the Times investigation published in November found that many suburbs in Los Angeles County have no active plans to renovate apartments that can cause these types of earthquakes.

In Northern California, the San Francisco Supervisory Board unanimously approved a measure Tuesday that would require owners of suspicious concrete buildings to conduct seismic assessments of their structures with engineers.

Analysis will help determine whether a particular building in an earthquake is at risk of special collapse or serious damage.

"This legislation helps us understand the actual risks of building inventory and provides concrete building owners with clear voluntary guidance and remodeling options," City administrator Carmen Chu said in a statement.

However, San Francisco law does not require remodeling of fragile concrete buildings.

San Francisco officials estimate that half of all deaths and injuries will occur in concrete buildings in the expected hypothetical level 7.2 San Andreas fault earthquake.

A major drawback involves that concrete buildings are “non-ductile”, where steel reinforcement is insufficiently configured, and when shaken in an earthquake, the structure of the reinforcement causes the concrete to explode, a prelude to a catastrophic collapse. This flaw was discovered in the 1971 Silma tremor, and is now well known.

Concrete buildings previously collapsed in the Los Angeles earthquake, including the Kaiser Permanente clinic building and the bull market department store building during the 1994 Northridge earthquake, and the newly built Olive View Medical Center during the 1971 earthquake.

The collapse of concrete buildings has resulted in earthquake deaths in Türkiye, Mexico, Taiwan and New Zealand.

California cities need to renovate non-sugar-de-concrete buildings, including Los Angeles, Torrance, Santa Monica and West Hollywood.
