He received the American Geophysical Union's James B. Macelwane Medal in 1994. Vidale was born in Philadelphia, Pennsylvania, USA, studied physics and geology at Yale, and obtained his Ph.D. from Caltech in 1987. He then held research positions at UC Santa Cruz and the USGS, until he joined UCLA in 1995. In 2006, he moved to Seattle to direct the Pacific Northwest Seismic Network at the University of Washington. He was a Gutenberg Fellow at Caltech and a Gilbert Fellow of the USGS. Vidale is a Fellow of AGU and received AGU's Macelwane Medal.〔(【引用サイトリンク】 title=Macelwane medal )〕 He has studied the relation of Earth tides and earthquakes - finding only the strongest tides noticeably effect the timing of earthquakes,〔(【引用サイトリンク】 title=Wired )〕 earthquake swarms - finding they are a more general phenomenon than he previously suspected, the inner core - discovering high-frequency seismic waves scattered scattered therein that offer a second line of evidence it is rotating about 0.2 degrees per year,〔(【引用サイトリンク】 title=American Scientist ) 〕〔(【引用サイトリンク】 title=Science Now ) 〕 the stronger than expected healing of fault zones after an earthquake,〔(【引用サイトリンク】 title=Science Daily Article )〕 and various details of the seismic structure of the mantle.〔(【引用サイトリンク】 title=Science Daily )〕 Vidale also contributed an improved method of ray tracing which relied on a finite-difference approximation of the eikonal equation and which has been used widely in both earthquake and reflection seismology. There have been some controversies surrounding his research, including endorsements of risky experiments,〔(【引用サイトリンク】 title=The Science Show )〕〔(【引用サイトリンク】 title=KCET Life and Times )〕〔(【引用サイトリンク】 title=Geotimes )〕 misquotes,〔(【引用サイトリンク】 title=Pravda )〕 and mild ridicule〔(【引用サイトリンク】 title=It lurks under Barrow )〕 as well. ==External links== *(UW web page, including links to PDFs of 80 or so reviewed papers ) *(UCLA web page ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Vidale」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
