James O. "Jim" Berkland is an American geologist studying earthquake prediction. He claims to have developed a method for predicting earthquakes, and offers his predictions through media appearances and publications. Before his retirement, Berkland was the County Geologist for Santa Clara County, California for twenty-one years. He previously worked for the United States Bureau of Reclamation and for the United States Geological Survey. He has published over fifty scientific papers. == Career == Jim Berkland studied geology at the University of California, Berkeley earning the Bachelor of Arts degree in 1958. Thereafter he worked for the United States Geological Survey while pursuing graduate study. In 1964, he took a position at the United States Bureau of Reclamation. After further graduate study, he taught for a year at Appalachian State University, 1972–1973, then returned to California to work as County Geologist for Santa Clara County from 1973 until he retired in 1994. In an interview published on October 13, 1989, one day before the start of baseball's 1989 World Series, Berkland predicted that an earthquake with magnitude between 3.5 and 6.0 would occur in the San Francisco Bay Area between October 14 and October 21.〔''Gilroy Dispatch'' (Gilroy, California) "Is 'World Series' Quake Coming?", October 13, 1989〕 The 6.9-magnitude Loma Prieta earthquake occurred on October 17, just before the start of the third game of the Series. Berkland claims that government officials told him not to make any more predictions, fearing mass panic, and he was suspended for two months from his Santa Clara County geology position in late October, 1989. In an announcement on his Web site, Berkland predicted an earthquake for January 9–14, 2009. During that week, the largest earthquake on land was in Crete on 13 January with magnitude 5.3, while the largest California-area earthquake had magnitude 3.5.〔The United States Geological Survey lists (major earthquakes by year ). This data was confirmed by (searching all seismic events ) within Berkland's timeframe.〕 Interviewed on Fox News in March 2011, Berkland predicted a massive earthquake in California for sometime between March 19 and March 26, 2011. He cited as factors the highest tides in 18 years and the proximity of the Moon, suggesting that the quake will most likely strike on Saturday, March 19, 2011.〔 He also gave (predictions on the Fox News Channel )〕 Although, no major quakes occurred in California above 3.5, the 2011 Tohoku 9.0 magnitude earthquake and tsunami struck Japan just 8 days prior to Berkland's predicted timeline on March 11. Another powerful earthquake that same month occurred in Myanmar on 24 March with magnitude 6.9.〔 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「Jim Berkland」の詳細全文を読む スポンサード リンク
