Question: Is A Magnitude 9 Earthquake Possible?

What size earthquake would destroy the earth?

The energy needed to destroy the Earth is 2 x 10^32 joules or about 200000000 yottajoules (10^24 joules).

That is incredibly big.

For comparison, the biggest earthquake, a magnitude 9.5 earthquake off the coast of Chile, registers as 1 x 10^19 joules, or 10 exajoules..

Where is safest place in earthquake?

From this came our belief that a doorway is the safest place to be during an earthquake. True — if you live in an old, unreinforced adobe house or some older wood-frame houses. In modern homes, doorways are no stronger than any other part of the house.

What would happen in a 12.0 earthquake?

since a 9+ is the largest ever and a 9 is 10 times an 8 and a 10 is 10 times a 9 and an 11 is 10 times a ten and a 12 would be 10 times an 11, that would be about 10,000 times stronger than the strongest earthquake ever, it would cause catastrophic plate tectonic shifting and could possibly fracture the earth in …

What does a 7.0 earthquake feel like?

Intensity 7: Very strong — Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken. Intensity 6: Strong — Felt by all, many frightened.

How long does a magnitude 9 earthquake last?

Their guess? About 15 to 20 minutes. Of course, that’d be following a mighty powerful earthquake as well. “With a magnitude 9.0 event you’re expecting a severe amount of shaking,” Dan Eungard, one of the scientists who published the report, said.

Can an earthquake split the earth?

Shallow crevasses can form during earthquake-induced landslides, lateral spreads, or from other types of ground failures, but faults do not open up during an earthquake. … If a fault could open up, no earthquake would occur in the first place because there would be no friction locking the two blocks together.

How far can a 7.0 earthquake be felt?

Nor do USGS earthquake experts expect the M7. 7 earthquake to change the behavior of the earthquake sequence in Southwestern Puerto Rico. The distance between the earthquakes in southwestern Puerto Rico and today’s M 7.7 is approximately 1,250 kilometers or nearly 800 miles.

What would a magnitude 10 earthquake be like?

No magnitude 10 earthquake has ever been observed. The most powerful quake ever recorded was a magnitude 9.5 temblor in Chile in 1960. 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.

What’s the longest an earthquake can last?

Indian Ocean Earthquake With a magnitude of between 9.1 and 9.3, this earthquake is the second largest ever recorded, and it also had the longest duration, lasting between eight and 10 minutes. Devastating tsunamis hit land masses bordering the ocean, prompting a widespread humanitarian response.

Is a magnitude 11 earthquake possible?

There is nowhere on Earth where a magnitude 11 Earthquake can happen. The biggest earthquakes know are all Megathrust ones on Subduction zones- and the top out about 9.4, 9.5. California does not have the large subduction zone needed for such a quake. It has slip-strike movement, and probably can’t exceed an 8.0 or so.

Will California sink 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. … There is nowhere for California to fall, however, Los Angeles and San Francisco will one day be adjacent to one another!

Can San Andreas really happen?

No. Magnitude 9 earthquakes only occur on subduction zones. As stated above, there hasn’t been an active subduction zone under San Francisco or Los Angeles for millions of years. … However, earthquake intensity along the modern-day San Andreas fault maxes out at approximately 8.3 (The Hollywood Reporter).

Is a magnitude 12 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.

Has there ever been a 12.0 earthquake?

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. … The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake” in its own right.
