Phys.org / How climate change may amplify the impact of earthquakes in the Arctic

Permafrost refers to permanently frozen ground. The rock is held together by ice, much like cement binds concrete. However, when the ice thaws, the ground becomes weak and unstable. During an earthquake, this can trigger ...
