A 6.4-magnitude and 7.1-magnitude earthquake struck southern California on July 4 and 5, setting a new record for the strongest earthquake to hit the region in nearly 20 years. A state of emergency has been declared in richcrest and SAN bernardino counties, but no deaths have been reported. Earthquake experts don't expect to rule out another quake of magnitude 7 or higher in the coming week.

A record for the strongest earthquake in nearly 20 years

The fourth of July quake had a magnitude of 6.4 and the evening of July 5 had a magnitude of 7.1, making it the strongest earthquake to hit southern California in nearly two decades, according to the U.S. geological survey.

The two-day quake was centered near the southern California town. About 270 kilometers from Los Angeles and surrounding cities and 380 kilometers from Las Vegas, Nevada. The quake on Friday was felt in Los Angeles and Las Vegas. Residents described the experience as "a house shaking like a plane in turbulence" and "the ground roaring".

Seismologists believe that because the quakes were less than 48 hours apart and had close epicentres, the 6.4-magnitude quake was a foreshock, while the 7.1-magnitude quake was the main one, six times stronger and releasing.

Experts expect more aftershocks in the future. According to the usgs, there is a 50% or greater chance of a magnitude 6 earthquake occurring in the next few days. Some experts estimate there is a one-in-ten chance that southern California will experience another earthquake of magnitude 7 or greater next week.

"Break out" every 10 to 20 years?

Although California is known as a "paradise on earth" for its sandy beaches, it is also one of the most dangerous places on earth because of its high number of earthquakes.

In the early hours of April 18, 1906, an 8.3-magnitude earthquake struck San Francisco, one of the worst natural disasters in U.S. history. The epicenter was on the SAN andres fault near San Francisco, and the fault slipped as much as six meters.

A few seconds after the quake, San Francisco was reduced to rubble and set off a fire that lasted three days and three nights. According to statistics, in the earthquake and the fire, 10 square kilometers of urban ashes, at least 3,000 people died, the direct economic losses of about 400 million us dollars.

After the earthquake in San Francisco, Americans began to pay attention to the earthquake, gradually cultivate the awareness of earthquake disaster, and promote the development of earthquake science. The last time California was hit by an earthquake of magnitude 7 or greater was 20 years ago. On October 16, 1999, a 7.1-magnitude earthquake struck the mojave desert region of southern California, but caused no serious damage.

"In California, we expect a magnitude 7 earthquake every 10 to 20 years," said Lucy Jones, a seismologist at the California institute of technology. On January 17, 1994, a 6.6 magnitude Northridge earthquake struck southern California, with its epicenter in the densely populated Los Angeles area, killing dozens of people and causing billions of dollars in property damage. On August 24, 2014, a magnitude 6.0 earthquake struck the San Francisco bay area, California, injuring more than 100 people and damaging more than 2,000 buildings.

Plate boundaries are the "culprits"

California is prone to earthquakes because of its unique geology. California sits between the north American plate and the Pacific plate, which is crisscrossed by fault systems and other active systems that move the earth's crust.

California has hundreds of known faults, with more than 70 percent of the population living within 50 kilometers of a fault that could cause a major earthquake. Southern California is dotted with more than 200 faults, large and small, that can trigger quakes ranging in magnitude from 5.0 to 7.8.

The SAN andreas fault is a constant fear for californians. The densely populated cities of palm springs, Los Angeles and San Francisco sit on the SAN andreas fault. The fault is one of the most stratigraphically active areas on earth, accumulating seismic stress every year. The fault system is estimated to produce large, destructive earthquakes every few decades.

A report last year by the geological survey warned that the risk of a major earthquake hitting California was increasing. Over the next 30 years, the likelihood that California will experience an earthquake of magnitude 8 or greater has risen from about 4.7 percent to about 7 percent.
