A 3.8 magnitude earthquake struck Southern California near San Bernardino County on Thursday night, according to the United States Geological Survey.
The earthquake occurred outside Ontario, about six miles south of Rancho Cucamonga and about 18 miles southwest of San Bernardino, the USGS said, and could be felt as far away as Los Angeles and Huntington Beach.
The USGS said the earthquake originated about eight miles underground and occurred around 11:38 p.m. local time on Thursday. There were no immediate reports of damage or injuries.
The earthquake occurs days later Nearly 20 earthquakes hit parts of Southern California within a short period of time.
The first earthquake recorded on February 11 occurred just northwest of El Centro, California. It was measured at a magnitude of 4.8, according to the USGS, and from there the earthquakes continued around El Centro and Imperial, two cities located east of San Diego and close to the border with Mexico.
At what magnitude does damage begin to occur in earthquakes?
According to the USGS, there is no magnitude above which damage occurs. It depends on other variables, such as the distance from the earthquake, the type of soil in which it is located, the construction of the building, among others. However, the USGS says that damage usually does not occur until the magnitude of the earthquake reaches something greater than 4 or 5.
