The depth of the earthquake was estimated at 10.7 kilometres.

The epicentre is near the small town of Ridgecrest (population 28,000) and a US Navy military base, the Naval Air Weapons Station China Lake, a vast desert area where bombs and missiles are tested.

An official at the base told AFP that there were “fires, water leaks, leaks of dangerous products” but the commander-in-chief Paul Dale later assured at a conference of Ridgecrest told them that his men “continued to assess the damage.” He did not want to give more details.

Light wounded

Witnesses interviewed by American TVs told how jolts opened drawers, dropped televisions and especially caused panic among many residents.

The firefighters have finished their assessment and “Los Angeles is in great shape,” said Mayor Eric Garcetti.

“Hundreds of earthquakes”

California is the most populous state in America, but the epicentre of the earthquake has been located in the Mojave Desert, a large, sparsely populated area.

“There have been hundreds of earthquakes today (Thursday)”, some of which exceed magnitude 4, said at a press briefing the seismologist Lucy Jones, referring to a “large number of aftershocks”.

The specialist confirmed it was the strongest shock in southern California since 1999. According to the Los Angeles Times, this is a magnitude 7.1 earthquake that affected the Twentynine area Palms that year.

Lucy Jones said the earthquake did not occur along the famous San Andreas Fault, where experts fear a major earthquake that could cause chaos in Los Angeles and along the coast.

Thursday’s earthquake zone is “a region with lots of small but not big flaws” like the one in San Andreas, she explained.
