California hit by 7.1-magnitude earthquake, the strongest in 20 years

There's a chance of more over the coming days.

A 7.1-magnitude earthquake has hit California less than two days after another strong tremor, shaking parts of LA and causing fire and building damage near the epicentre.

Early magnitude estimates from the U.S. Geological Survey wavered between 6.9 and 7.1, making it the most powerful tremor in California for 20 years.

A 6.4 magnitude quake hit the same region on Thursday.

Seismologist Dr Lucy Jones said the quakes could continue.

"This is an earthquake sequence," she said at a press conference. "It will be ongoing."

"Every earthquake makes another earthquake more likely," she added while saying there's a 10% chance of another earthquake in the next week.

The earthquake was the largest to hit California in around 20 years and was felt in Las Vegas and as far south as Mexico.

Ridgecrest, where residents were still recovering from the previous quake, took the brunt of the damage.

There have been minor injuries, but no deaths have been reported so far.
