...However, the significant anomaly in seismic wave velocity that was the basis for this theory has never been observed in subsequent accurate observations (even if it was small), and the occurrence of a series of earthquakes in and around the Izu Peninsula from 1974 to 1980 was different from the model's predictions. This led to the need to reexamine the mechanism claimed by this model, and the extreme optimism gradually faded away. In China, the destructive earthquake that occurred near Haicheng in Liaoning Province in February 1975 (known as the Haicheng earthquake, magnitude M 7.3) was successfully predicted, saving many lives. However, the Tangshan earthquake that occurred in the same country in 1976 could not be predicted. ... *Some of the terminology used in reference to the "Haicheng Earthquake" is listed below.

…しかし,その根拠とされた著しい地震波速度変化の異常がその後の精度のよい観測でいっこうに認められないこと(たとえあったとしても小さい)や,1974年から80年にかけて伊豆半島とその周辺で続発した地震の起こり方などがこのモデルの予測と違うことなどから,このモデルの主張する機構についても再検討の必要があるとされ,極端な楽観論もしだいに影をひそめた。 中国では遼寧省海城近くで1975年2月発生した破壊地震(海城地震と呼ばれ,マグニチュードM7.3)の予知に成功し,多大の人命が救われた。しかし一方で,同じ中国で76年に起こった唐山地震の場合は予知できなかった。… ※「海城地震」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
