Giant fissures appear near epicenters of California's major earthquakes

There were multiple fissures that broke the ground in the Mojave Desert in southern California on Thursday and Friday after two major M6.4 and M7.1 earthquakes struck the area. The power of nature is amazing... And these deep fissures near Ridgecrest, California are just terrifying!

On the Fourth of July, people from Los Angeles to Las Vegas felt the ground shake. Books fell off library shelves, trees collapsed, and cracks spidered through building walls and highway asphalt.

The magnitude 6.4 earthquake was centered in the California city of Ridgecrest, about 175 miles northeast of Long Beach. It ended a five-year drought in California's seismic record: Before yesterday, the ground had not shook in the state since a magnitude 6 quake struck Napa in August 2014, causing $1 billion in damages.

Indonesia's geophysics agency has issued a tsunami warning, after a magnitude 7.1 earthquake struck in the Moloccan Sea to the country's east. The figure was later downgraded to 7.0

The quake struck shortly after 10 PM local time on Sunday, at a depth of 36km, the Indonesian Agency for Meteorology, Climatology and Geophysics reported. The earthquake's epicenter lies 180km southeast of Manado, a city with a population of 450,000, and 129km west of Ternate, home to 200,000.

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Comment: The quake superseded the previous day's 6.4 magnitude earthquake, on US Independence Day, which was the largest in Southern California for 20 years...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

socal earthquake july 2019
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 magnitude 6.7 earthquake was registered off the coast of the Kamchatka Peninsula in the Russian Far East on Wednesday, the regional branch of the Geophysical Survey of the Russian Academy of Sciences (GS RAS) said,Trendreports citing Sputnik.

"The magnitude 6.7 earthquake was registered off the east coast of Kamchatka. The epicentre of the earthquake was located at the depth of about 60 kilometres, 108 kilometres (67 miles) to the east of the locality of Ust-Kamchatsk", the GS RAS spokesperson said.

​According to the data of the regional branch of the Russian Emergencies Ministry, the tremors were felt in Ust-Kamchatsk. The quake has not resulted in any casualties or damage to infrastructure.

Comment: A 6.3 magnitude earthquake preceded the above event at the same location a day earlier.
