To 30 Thousands of aftershocks: aftershocks after earthquakes in California will last for several months

The authorities in Southern California reported that the effects of the strongest earthquake in the region over the past 20 years were not as large as they could have been. Also, the report said that after such an earthquake, the likelihood of strong aftershocks increased in the coming days, and possibly months, it writes APNews.

After the 7,1 earthquake, no fatalities or serious injuries were recorded. The earthquake was felt from Sacramento to Mexico and caused the evacuation of the only ground station of the China Lake naval air complex in the Mojave Desert.

The earthquake occurred on Friday, July 5, in 20: 19 in 11 miles (18 kilometers) from Ridzhkrest, where the day before this was recorded a very large 6,4 score. As a result of this earthquake, a lot of knowledge was destroyed, roads were broken, railways were blocked, and water and gas pipelines were damaged.

Light damage was largely due to the remoteness of residential areas from the center of the earthquake, but California Governor Gavin Newsom after a trip to Ridzhrest said that "at first you just can not see the effects of the earthquake."

Newsom estimated the economic damage to more than 100 million dollars and said that US President Donald Trump offered him federal support in rebuilding the area.

Seismologists warned that over the next six months, up to 30 thousands of aftershocks could occur in the Ridgekrest region.

April Hamlin said she "was already very scared" when an 7,1 magnitude earthquake hit Ridgecrest. She and her three children initially thought that this was another aftershock after the 4 earthquake in July.

“But the shaking just kept getting stronger,” Hamlin said. — The TV turned over and was hanging on the cord. And we heard it break. We also heard windows breaking throughout the house, but all we could do was stay put and wait until the earthquake was over."

Given the likelihood of repeated shocks and the temperature rise to 100 degrees Fahrenheit (38 degrees Celsius) over the next few days, officials took precautions.

According to Major General David Baldwin, the California National Guard sent troops, logistics, and airplanes to the 200 region. According to him, the Pentagon was notified, and the entire California military department was alerted.

The China Lake Naval Air Base stated that the workers had been evacuated and all operations at the base were stopped. Earthquake epicenters were at the base, and officials said they continue to assess the damage. Officials said that most of the employees live outside the base or in Ridzhkrest, but the military living at the base were evacuated.

Cots, water and food were brought to the California Emergency Department to meet the needs of evacuees, said Marc Gilarducci, director of rapid response services.

State authorities have closed the 30-mile (48-kilometer) section of the 178 highway between Ridzhkrest and the city of Throne south-west of Death Valley, due to significant collapses and huge cracks. California Department of Transportation spokeswoman Kristin Knadler said emergency crews worked all night to repair the roadway, but new cracks appeared on it.

In Ridzhkrest local firefighters and police said they were initially inundated with calls for help. But police chief Jed McLaughlin said that “by the grace of God, except for minor wounds, such as cuts and bruises,” there was no information about serious injuries.

According to McLaughlin, the fires were quickly extinguished, and the lines running on natural gas, where leaks were reported, were blocked.

When he was asked to describe what he had experienced over the past two days, the boss said: “Woe, shock, and then, pride that I became a part of it and helped people. It was a wide range of emotions, and I think that all of America is experiencing it now. ”

In Tron, a town with a population of about 2000, a man who is considered the gateway to Death Valley, firefighters reported damage to buildings around 50. The head of San Bernardino County, Robert Lovingud, said that the Federal Emergency Management Agency (FEMA) had delivered a tractor with drinking water to the city because of damage to the water mains. Newsom declared a state of emergency in the county.

Julia Doss, who runs the Trona Neighborhood Watch Facebook page, said the only grocery store in town, Family Dollar, was closed Saturday because of the earthquake.

“The only way to get food is to drive to Ridgecrest and I'm afraid that with only three gas stations in town we may soon run out of gas,” Doss wrote.

Antun Abdullatif, 59, owns wine shops and other businesses in Ridzhkrest and Tron.

“I would say 70% of my inventory is broken,” he said. “Every time I sweep up and throw broken things in the trash, I throw away $200.”

Lucy Jones, a Caltech seismologist and former research advisor for the US Geological Survey, said the second earthquake probably occurred along a fault line about 25 miles long (40 kilometers) and was part of an ongoing series of aftershocks. According to Jones, seismic activity is unlikely to affect fault lines outside the region, noting that the San Andreas giant fault is far away.

Later that day, Egill Hauksson, another seismologist at Caltech, said scientists believe that the ongoing series of shocks could lead to more than 30 000 earthquakes of magnitude 1 or more over the next six months. He said that the likelihood of a 7 magnitude jolt over the next week is about 3%, but one or two 6 magnitude earthquakes are expected.

As ForumDaily wrote earlier:

• Fourth of July in Southern California were recorded bumps magnitude 6,6. The epicenter was located in 18 kilometers northeast of the city of Ridzhkrest, the center was located at a depth of 8,7 kilometers.
• On July 5, hundreds of weaker aftershocks were observed in Southern California - aftershock. The power of most aftershocks ranged from 2 to 3 points, some from 3 to 4 points.
• It turned out that the early warning system, launched at the beginning of this year as part of a pilot program, didn't warn Los Angeles residents about the strong earthquake.
• July 5 evening in southern California 7,1 magnitude earthquake hit, the most powerful of the last 20 years. The aftershocks were recorded at 20: 19 local time. The epicenter of the earthquake was located in 193 kilometers north of Los Angeles, its center was located at a depth of ten kilometers.
• Fire, destruction, injury - such were the effects of the second per day powerful earthquake in california.
