Quick Answer: Can San Andreas Really Happen?

How far can a 9.0 earthquake be felt?

In the U.S.

Midcontinent, with layer-cake geology that makes efficient wave guides, a 9.0 event would probably produce appreciable damage 565 miles away..

Is a 10.0 earthquake possible?

No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. … 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.

Why is the San Andreas Fault so dangerous?

Basically, because it’s a big fault that is close to some big cities. … While it is not as likely to experience a 7.5-magnitude earthquake, the fault is close to San Francisco, so a magnitude 7+ earthquake could cause major damage to the San Francisco Bay Area and kill or injure thousands.

Would a 7.1 earthquake destroy the Hoover Dam?

Blast the dam loose from the rock on both sides, and Hoover will just sit there while the water squirts around the sides where the rock was damaged. It would be very, very hard to significantly damage Hoover with a quake of any possible magnitude.

How long does a 9.0 earthquake last for?

five minutesA magnitude 9.0 earthquake can last for five minutes or longer, and the amount of energy released is about 1,000 times greater than that of a 7.0. According to the U.S. Geological Survey, the most powerful quakes could leave few if any masonry buildings standing, destroy bridges and toss objects into the air.

What if a big earthquake hits California?

Narrator: The quake could kill about 1,800 people and leave 50,000 or more with injuries. While people could die from falling debris and collapsed structures, the highest death toll would be from fires.

Is the tsunami in San Andreas possible?

The possibility of the San Andreas fault triggering a tsunami on its own is highly unlikely, but there is the potential for an underwater landslide forcing one, according to San Diego State University seismologist Tom Rockwell. Yes, it is possible.

Can California fall into the ocean?

Will California eventually fall into the ocean? No, California is not going to fall into the ocean. California is firmly planted on the top of the earth’s crust in a location where it spans two tectonic plates. … The strike-slip earthquakes on the San Andreas Fault are a result of this plate motion.

How likely is San Andreas earthquake?

Narrator: On average, the San Andreas Fault ruptures every 150 years. The southern parts of the fault have remained inactive for over 200 years. … According to a 2008 federal report, the most likely scenario is a 7.8 magnitude quake that would rupture a 200-mile stretch along the southernmost part of the fault.

How overdue is the San Andreas Fault?

But the cycle time for breaks and earthquakes on the San Andreas fault is 130 years, so we are way overdue.” A 6.4-magnitude quake hit near Ridgecrest at 10:33 a.m. Thursday, followed by a 7.1-magnitude quake in the same region at 8:19 p.m. Friday, the USGS reported.

What a 10.0 earthquake would do?

A magnitude 10 quake would likely cause ground motions for up to an hour, with tsunami hitting while the shaking was still going on, according to the research. Tsunami would continue for several days, causing damage to several Pacific Rim nations.

Is a 12.0 earthquake possible?

Due to the logarithmic nature of the magnitude scale, it would require a fault larger than the circumference of the Earth. It should be noted that it is literally physically impossible for a magnitude 12 earthquake to happen on earth, as the earth is not big enough to contain a fault long enough to produce that.

What happens if San Andreas Fault breaks?

The San Andreas extends into Mexico. If the fault breaks there of course the country would feel a tremendous impact. But in the U.S., most of the buildings will do okay. It’s more the damage to the infrastructure and getting started again that’s the problem.

How far can a tsunami go in LA?

The Japanese tsunami was 39 meters – about 128 feet high and traveled 10 kilometers inland (6 miles). In comparison, downtown Los Angeles is 285 feet above sea level, and is about 11 miles from the Marina, which is one low point of the coast.

Will California break off?

No, California is not going to fall into the ocean. California is firmly planted on the top of the earth’s crust in a location where it spans two tectonic plates. … There is nowhere for California to fall, however, Los Angeles and San Francisco will one day be adjacent to one another!
