Earthquakes and tsunamis: high school textbook


Earthquakes are as inescapable as the weather. Even Mars and the Moon have them. Here on Earth, seismologists report that every year there are a couple of million earthquakes strong enough to be felt, a thousand or so that can bring down chimneys, and about a dozen capable of producing disasters. One of consequences of major impact to people is generated by those big magnitude earthquakes with hypocenter located at the sea. When they occur, sea waves can be generated which propagate very quickly across the ocean and produce casualties not only in the source area but along coastlines located thousands of miles away.
