阿拉斯加科迪亚克市东北65英里发生4.2级地震,海啸预警中心称没有海啸危险

美国地质调查局(USGS)测定,阿拉斯加州科迪亚克岛自治市镇的科迪亚克市(Kodiak City)东北65英里处,当地时间11月13日下午2时26分发生4.2级地震,震源深度17英里。美国国家海啸预警中心随后发布第1号海啸信息声明,明确表示这次地震没有海啸危险。
按预警中心公布的初步参数,震中位于北纬58.4度、西经151.0度,在安克雷奇以南约200英里。地质调查局的测定把震中标在科迪亚克岛北侧的 Ouzinkie 村东北偏东99公里一带,与预警中心的位置指向同一片海域。
这份声明由设在阿拉斯加州 Palmer 的国家海啸预警中心于当地时间下午2时30分发出。声明说,上述参数来自快速初步评估,后续可能调整;除非有新的信息,这将是该中心就这次地震发出的唯一一份公报,进一步信息由地质调查局或相应的区域地震台网发布。
两份官方通告都没有提及人员伤亡或财产损失。

Magnitude 4.2 Earthquake Strikes 65 Miles Northeast of Kodiak City, Alaska; Tsunami Warning Center Says No Tsunami Danger
The U.S. Geological Survey (USGS) recorded a magnitude 4.2 earthquake 65 miles northeast of Kodiak City, in Alaska's Kodiak Island Borough, at 2:26 p.m. Alaska time on November 13, at a depth of 17 miles. The U.S. National Tsunami Warning Center then issued Tsunami Information Statement Number 1, stating plainly that there is no tsunami danger from this earthquake.
According to the warning center's preliminary parameters, the epicenter was at 58.4 degrees north latitude and 151.0 degrees west longitude, about 200 miles south of Anchorage. The USGS located the epicenter 99 kilometers east-northeast of the village of Ouzinkie, on the north side of Kodiak Island, pointing to the same waters as the warning center's location.
The statement was issued at 2:30 p.m. local time by the National Tsunami Warning Center in Palmer, Alaska. It said the parameters are based on a rapid preliminary assessment and may change, and that this will be the only message the center issues for this event unless additional information becomes available, with further information to come from the USGS or the appropriate regional seismic network.
Neither official notice mentioned any casualties or property damage.
