Earthquake-caused tsunamis as severe as those that swept southeast Asia on Sunday have happened in the past off the Oregon coast, according to a University of Oregon geoscientist.
In fact, a tsunami caused by a magnitude 9.0 earthquake occurred on Jan. 26, 1700, wiping out Oregon tribal villages in low-lying coastal estuaries and causing damage as far away as Japan ... EurekAlert!
The deadly Asian earthquake may have permanently accelerated the Earth's rotation - shortening days by a fraction of a second - and caused the planet to wobble on its axis, U.S. scientists said on Tuesday ... Reuters.com
A tsunami (from Japanese 津波 meaning wave in port or "harbour wave") or tidal wave is one or a series of deep water ocean waves that can occur after a large earthquake (having a vertical component of movement), seaquake, volcanic activity, landslide, slumps, or meteorite impacts in or near the sea. They are sometimes referred to as tidal waves as they often resemble a tide that keeps rising, rather than cresting waves when they reach shore. However, the term is misleading as tsunamis are not caused by tides, and its use is discouraged by oceanographers. While it has also been noted that tsunamis often have little to do with harbors (despite the Japanese translation of the word), the term "tsunami" is used exclusively to refer to water surges caused by physical displacement of water and is thus more correct ...

In parts of Fairbanks, Alaska, houses and buildings lean at odd angles.
Some slump as if sliding downhill. Windows and doors inch closer and closer to the ground.
It is an architectural landscape that is becoming more familiar as the world's ice-rich permafrost gives way to thaw.
Water replaces ice and the ground subsides, taking the structures on top along with it.
Alaska is not the only region in a slump. The permafrost melt is accelerating throughout the world's cold regions, scientists reported at the recent Fall Meeting of the American Geophysical Union (AGU) in San Francisco ... BBC NEWS
