eli5: why is it impossible to get a magnitude 10 earthquake
In: 4021
It is technically possible to have a magnitude 10 earthquake. The problem is that it requires a truly massive area to register as such. The fault line would basically have to run the length of the Earth, and no such fault line exists, which is why it is classified as “impossible”. *However*, if you include non-tectonic sources – like an asteroid slamming into Earth – then you could have magnitudes of really any quantity.
