时近中午,在堪察加半岛彼得罗巴甫洛夫斯克(苏联远东地区)无线电和电视广播突然中止,并且发出了紧急通知:在最近几小时内可能有地震。不久,在市区街道上又响起了警报器。苏联《真理报》2月22日报道说,这是苏联首次在堪察加开始进行的“当受到强烈地震威胁时保障居民安全”的群众性演习时的情景。 Nearly noon, radio and television broadcasting in Petropavlovsk-Kamchatsky (the Far East of the Soviet Union) abruptly ceased and an urgent circular was issued: There could be an earthquake in the last few hours. Soon, sirens sounded in the downtown streets. The Soviet newspaper Pravda reported on February 22 that this was the first time the Soviet Union conducted mass exercises “to protect the safety of residents when a strong earthquake threatened” that began in Kamchatka.
