The world's largest earthquake with an instrumentally documented magnitude occurred on May 22, 1960 near Valdivia, in southern Chile. It was assigned a magnitude of 9.5 by the United States Geological Survey..
Similarly one may ask, has there ever been a 10.0 earthquake?
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.
Likewise, how bad is a 9.5 earthquake? The largest earthquake ever recorded wa a magnitude-9.5 temblor that ripped along the coast of southern Chile on May 22, 1960. That means a magnitude-8.0 earthquake is 33 times stronger than a 7.0, and a magnitude-9.0 earthquake is 1,089 (33 x 33) times more powerful than a 7.0 — the energy ramps up fast.
Subsequently, question is, has there ever been a 9.0 earthquake?
The world's first recorded magnitude 9.0 earthquake struck off the east coast of Kamchatka in 1952. The quake generated a 43-foot tsunami (13 m) locally. The tsunami rocked Crescent City, Calif., which was also hit hard by the recent Japan earthquake.

Will the Big One cause a tsunami?
And, no, the quake would not cause a tsunami, despite what movies would have you believe. 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.Can an earthquake split the earth?
The short answer is no. Generally earthquakes occur along the edges of two tectonic plates that bump up against one another or slip past one another. The plates often stick together at points known as faults.How big is a 6.5 earthquake?
| Magnitude | Earthquake Effects | Estimated Number Each Year |

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).What is the deadliest tsunami in history?
Indian Ocean Tsunami
What would happen if the big one hit?
This could rupture high-pressure gas lines, releasing gas into the air and igniting potentially deadly explosions. Stewart: So, if you have natural-gas lines that rupture, that's how you can get fire and explosions.Can animals predict earthquakes?
Can animals predict earthquakes? Anecdotal evidence abounds of animals, fish, birds, reptiles, and insects exhibiting strange behavior anywhere from weeks to seconds before an earthquake. However, consistent and reliable behavior prior to seismic events, and a mechanism explaining how it could work, still eludes us.What are the biggest earthquakes in history?
