Has there ever been a 10.0 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. That is, the longer the fault, the larger the earthquake.
Why is a 10.0 earthquake impossible?
So, to have a 10 you would need a million square kilometer rupture. The largest earthquake ever recorded was Chile in 1960, wave energy magnitude of 9.5. The rupture was 1000 x 600 km. You would need almost twice as much rupture area for a 10, which means twice as long, because you can’t go deeper than 600 km.
How overdue is the big one earthquake?
California is located in a hot-zone of fault lines that can rupture without warning. Parts of the San Andreas fault have not ruptured in over 200 years, meaning it’s overdue for a high-magnitude earthquake commonly referred to as “The Big One.”
