Earthquake prediction is an immature science – it has not yet led to a successful prediction of an earthquake from first physical principles. Research into methods of prediction therefore focus on empirical analysis, with two general approaches: either identifying distinctive precursors to earthquakes, or identifying some kind of geophysical ...

The Aleutian Trench, of the southern coast of Alaska and the Aleutian Islands, where the North American plate overrides the Pacific plate, has generated many major earthquakes throughout history, several of which generated Pacific-wide tsunamis, [22] including the 1964 Alaska earthquake; at magnitude 9.1–9.2, it remains the largest recorded ...
JUNEAU, Alaska (AP) — A magnitude 7.5 earthquake prompted a tsunami warning Monday for a nearly thousand-mile stretch of Alaska’s southern coast, with waves over 2 feet at the nearest ...
