Was San Andreas real?
No. The San Andreas is actually mostly on land. Big tsunamis are created by faults underwater. The San Andreas fault is also vertical.

Is a magnitude 20 earthquake coming?
With all that considered, a magnitude 20 earthquake seems pretty impossible. So there’s nothing to worry about. Oh, right, except for that. One way that a magnitude 20 earthquake could occur would be due to a massive asteroid impact.
What does earthquake have the highest magnitude?
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. It is referred to as the “Great Chilean Earthquake” and the “1960 Valdivia Earthquake.”.
What is the highest magnitude earthquake possible?
The biggest earthquake ever recorded was a magnitude 9.5. It occurred in 1960 in Chile, where the Nazca plate subducts under the South American plate . There is no theoretical limit to the magnitude of an earthquake, although it is estimated that an earthquake of magnitude 11 would split the Earth in two.
How do you measure earthquake intensity?
The Mercalli Intensity Scale measures the intensity of an earthquake by observing its effect on people, the environment and the earth’s surface. The Richter Scale measures the energy released by an earthquake using a seismograph.
How to measure an earthquake?
Earthquakes are measured using seismographs, which monitor the seismic waves that travel through the Earth after an earthquake strikes. Scientists used the Richter Scale for many years but now largely follow the “moment magnitude scale,” which the U.S. Geological Survey says is a more accurate measure of size.
