Question

What is a quake lake?

Answer 1

A quake lake is formed when a river flowing through high canyon walls, has those walls collapse during an earthquake, forming a dam - the dam is not exactly constructed to be permanent, and can collapse any time - so if it is allowed to continue to restrain water, downstream areas are at a tremendous risk of flood should the dam collapse...
