You see, the largest temblor ever recorded anywhere on earth (9.5) occurred in Chile (1960).

Can San Andreas really happen?

Yes. In the San Andreas movie, a 9.6 magnitude earthquake hits San Francisco, which was triggered by a 9.1 magnitude quake in Los Angeles, following a 7.1 in Nevada. U.S. Geological Survey seismologist Dr. … In 1992, a 7.3 quake hit Southern California and triggered a 5.7 in Nevada (NPR.org).

Is a 10.0 earthquake possible?

No, earthquakes of magnitude 10 or larger cannot happen. … No fault long enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would extend around most of the planet.

What is the longest earthquake ever recorded?

Valdivia EarthquakeThe very largest quake ever to be recorded was the Great Chilean Earthquake (Valdivia Earthquake) on 22 May 1960. At magnitude 9.5, it was about as large as an earthquake according to geophysical laws can be.

Is California going to have a big earthquake?

No one can predict with certainty when the next massive earthquake— aka “The Big One”—will rock Southern California. But new research suggests it might be sooner than we previously thought.

What would happen if California broke off?

The lines that bring water, electricity and gas to Los Angeles all cross the San Andreas fault—they break during the quake and won’t be fixed for months. … Overall, such a quake would cause some $200 billion in damage, 50,000 injuries and 2,000 deaths, the researchers estimated.

Has there ever been a tsunami in California?

The last tsunami to hit California came from Japan, damaging more than 100 boats in Santa Cruz. The magnitude 9.0 earthquake in 2011 triggered a massive wave that traveled 5,000 miles across the ocean, causing damage up and down the West Coast as far south as San Diego. … In 1964, a magnitude 9.2 quake hit Alaska.

What will happen if a mega earthquake hits California?

According to The ShakeOut Scenario, a 7.8 earthquake hitting along the southern San Andreas fault on a non-windy day at about 9:00 a.m. will unfold, approximately, like this: 1,800 people will die. 1,600 fires will ignite and most of those will be large fires.

What size earthquake would destroy California?

The U.S. Geological Survey has projected that a magnitude 7 earthquake on the San Francisco Bay Area’s Hayward fault could lead to 800 deaths and 18,000 injuries. A magnitude 7.8 on the San Andreas fault in Southern California could be even more catastrophic, causing 1,800 deaths and 50,000 injuries.
