Anybody ever heard of "fore shocks"? Scientists will tell you that they don't know what are "fore shocks" and what are "after shocks" until AFTER the actual earthquake and its "after shocks" and the region returns to normalcy. Just because there is an earthquake doesn't mean that "after shocks" are coming... It may be these are "fore shocks" of something getting ready to happen. Not trying to spread fear just letting you know NOBODY KNOWS until its history - and the scientists/geologists even admit it.
