Brian Franklin Atwater (born September 18, 1951) is a geologist who works for the United States Geological Survey and is also a research professor at the University of Washington. ''Time'' magazine nominated him as one of the 100 most influential people in 2005, along with the likes of Spike Lee and Ziyi Zhang.
==Career==
Atwater has spent much of his career studying the likelihood of large earthquakes and tsunamis in the Pacific Northwest region of North America. In 2005, he published a book with others, "The Orphan Tsunami of 1700," that summarizes the evidence for a moment magnitude 9 earthquake in the Northwest on 26 January 1700, known as the 1700 Cascadia earthquake. The earthquake produced a tsunami so large that contemporary reports in Japan noted it, allowing Atwater's team to assign a precise date and approximate magnitude to the earthquake. Its occurrence and size are confirmed by evidence of a dramatic drop in the elevation of Northwest coastal land, recorded by buried marsh and forest soils that underlie tidal sediment, the deposition of a layer of tsunami sand on the subsided landscape, the death or injury of affected trees (see dendrochronology), and descriptions of the earthquake and tsunami in regional Amerindian legends.
