Could an earthquake destroy the world?

Earthquakes are not typically considered existential or even global catastrophic risks, and for good reason: they’re localized events. While they may be devastating to the local community, rarely do they impact the whole world.

Is a magnitude 11 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. That is, the longer the fault, the larger the earthquake.

Do many small earthquakes mean a big one is coming?

Small cluster of earthquakes may be warning sign of larger one to come, researcher says. Most earthquakes we feel come after smaller ones. That’s according to a new study as scientists try to predict when and where earthquakes might occur. Here’s what researchers have learned.
