What would a magnitude 15 earthquake be like?
It would leave nothing standing. Assuming you mean 15 along (a derivative of) the Richter scale, that earthquake would be 500,000 times stronger than the strongest recorded earthquake. It’s also by all accounts impossible, as rocks can’t build up the stress required before permanently deforming.
What would happen if there was an earthquake in Vancouver?
