菲律賓、萬那杜三強震　南太平洋十餘國發海嘯警報 2009.10.08 NowNews

http://tw.news.yahoo.com/article/url/d/a/091008/17/1skc6.html


太平洋地區今天(8日)連續發生三起強震。菲律賓的民答那峨外海，在台北時間上午
5點41分發生一起芮氏規模6.7強震，接著在6點03分與6點18分，南太平洋島國萬那杜
外海，接連發生規模7.8以及7.3強震，夏威夷的太平洋海嘯中心對包括紐、澳、印尼、
等南太平洋十多國，發佈海嘯警報。

根據美國地質調查所表示，發生在萬那杜規模7.8的地震深度為35公里，屬於淺層地
震，地震發生後，位於夏威夷的太平洋海嘯警報中心隨即對澳洲、紐西蘭、印尼、索
羅門群島、巴布亞紐幾內亞、斐濟、吐瓦魯等南太平洋十幾個國家發佈海嘯警報，在
警報範圍內的國家，也緊急撤離沿海居民，目前還不清楚當地是否有任何人員傷亡。

地質專家格蘭特表示，「規模7.8地震被視為強震，如果(震央)夠淺，震度也夠強的
話，的確會引發海嘯，但我們還不能確定。」發生在菲律賓的6.7地震，深度為320公
里，屬於深層地震，並沒有造成海嘯的威脅。
