Has there ever been a 9 earthquake?

The most powerful quake was the 9.5-magnitude Valdivia Earthquake that struck in Chile in 1960, according to the U.S. Geological Survey (USGS). That quake created a tsunami, which together killed an estimated 5,700 people. The 2004 Indian Ocean tsunami registered a 9.3 magnitude.

Will the big one hit Seattle?

Earthquake experts lay out latest outlook for the ‘Really Big One’ that’ll hit Seattle. … “We say that there’s approximately a 14% chance of another approximately magnitude-9 earthquake occurring in the next 50 years,” said Erin Wirth, a geophysicist at the University of Washington and the U.S. Geological Survey.

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.

What would a 10.0 earthquake 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.

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).
