Would a 7.1 earthquake destroy the Hoover Dam?
As such, it it susceptible to catastrophic failure if a large enough quake breaks the concrete loose from the canyon on EITHER side. Given the distance to any major faults, it would take a doozy of a quake, though. … It would be very, very hard to significantly damage Hoover with a quake of any possible magnitude.

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.
Is a 12.0 earthquake possible?
The magnitude scale is open-ended, meaning that scientists have not put a limit on how large an earthquake could be, but there is a limit just from the size of the earth. A magnitude 12 earthquake would require a fault larger than the earth itself.
What size earthquake would destroy the earth?
|Magnitude||Earthquake Effects||Estimated Number Each Year|
|6.1 to 6.9||May cause a lot of damage in very populated areas.||100|
|7.0 to 7.9||Major earthquake. Serious damage.||20|
|8.0 or greater||Great earthquake. Can totally destroy communities near the epicenter.||One every 5 to 10 years|
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.

The shaking will feel violent and it will be difficult to stand up. The contents of your house will be a mess. A large earthquake far away will feel like a gentle bump followed several seconds later by stronger rolling shaking that may feel like sharp shaking for a little while.
Is it safer to be outside during an earthquake?
Don’t run outside. Trying to run in an earthquake is dangerous, as the ground is moving and you can easily fall or be injured by debris or glass. Running outside is especially dangerous, as glass, bricks, or other building components may be falling. Again, you are much safer to stay inside and get under a table.
