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

It hit at 8.19pm local time 11 miles from Ridgecrest in the Mojave Desert, the site of Thursday's 6.4-magnitude quake.

Offices in downtown Los Angeles shook for around 30 seconds and it was also felt in the Hollywood Hills, Las Vegas and parts of Mexico.

The earthquake is the strongest to hit the region in 20 years, with experts giving it an early rating of 6.9 to 7.1 on the Richter scale.

There are "significant reports of structure fires, mostly as a result of gas leaks or gas line breaks" in Ridgecrest, said Mark Ghillarducci, head of the California Office of Emergency Services.

He said the full extent of the damage would not be revealed until daybreak on Saturday.

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



Comment: The quake superseded the previous day's 6.4 magnitude earthquake, on US Independence Day, which was the largest in Southern California for 20 years... until this latest one.

This is therefore the 10th most powerful in SoCal's history. Not long until The Big One?

Locals have been posting photographs of enormous dents and cracks on roads, as well as this picture of a highway blocked by large rocks from a rockfall:

6.4M earthquake rattles LA on Independence Day: Strongest to hit SoCal in 20 years - UPDATE 5.0 aftershock recorded

An 6.4 magnitude earthquake struck Southern California Thursday, the largest temblor to hit the region in decades.

The quake was centered in the Searles Valley, a remote area of San Bernardino about 100 miles from Los Angeles.


Comment: This is located in the Mojave Desert, aka Death Valley.


It was unclear of the temblor caused major damage or injuries.

The quake was the largest in Southern California since the 1994 6.6 Northridge quake, which killed dozens and caused billions in damage. But Northridge hit in the center of a populated area, while Thursday's quake was located far from the metropolitan Los Angeles area.


Comment: Actually, the earthquake was the strongest since a 7.1 quake struck in the region on October 16, 1999.




Comment: The Santa Monica Observer reports:
An earthquake at 10:33 pm PST on July 4 was felt from Santa Barbara to San Diego, and as far East as Las Vegas.

The temblor went on for over a minute. It was felt throughout the Westside of Los Angeles County as a powerful rolling motion. The quake was centered 12 KM southwest of Searles Valley California. It registered a preliminary magnitude of 6.4 on the Richter scale makes it probably the biggest southland shock in 25 years, since the 1994 Northridge Earthquake.

Searles Valley is near Death Valley, in Eastern Southern California's Mojave Desert, San Bernardino County. The earthquake was at 8.7 KM depth.

The earthquake occurred during Santa Monica's annual 4th of July parade. Stilt walkers wondered why they suddenly felt off balance, and cars in the parade shook from side to side.

If we could offer our readers a word of advice, don't drive right now, especially on area freeways. Firefighters and Police must check the roads and bridges for potential collapse. After the Northridge quake, bridges fell down and a handful of people were injured or killed driving off of them. This earthquake seems to have had similar intensity.

A powerful 7.3 magnitude earthquake struck near to Indonesia's Tanimbar islands in the Banda Sea Monday, with tremors being felt as far away as northern Australia.

The earthquake hit at a depth of about 208 kilometers (129 miles), according to the United States Geological Survey (USGS). That's considered an intermediate depth, meaning the quake was less likely to cause shaking on land than one closer to the Earth's surface.

Still, residents in the Australian city of Darwin, approximately 720 kilometers away (450 miles), said they could feel shaking due to the seismic activity.
