4年前,两位科学家警告加州南部正在进入一个可能会发生较大地震的活动期,并说该地区在这个月(即1987年11月——译注)最易发生地震。这两位科学家假设,该地区某种断层上的较大地震可能与少见的日食和月食有关。加州因皮里尔河谷在星期一日落和星期二日出前后发生的两次地震似乎支持了他们的理论。因此,有人会认为这两位科学家会因这周的两次地震而沾沾自喜。然而,他们俩中至少有一人并非如此。加州大学洛杉矶分校的地球物理学家诺波夫(Leon Knopoff)说:“这两次
Four years ago, the two scientists warned that southern California is entering an active phase of a possible major earthquake and said the region is most prone to earthquakes this month (November 1987). The two scientists hypothesized that a major earthquake on a fault in the area may be related to the rare solar eclipses and eclipses. Two earthquakes that took place in California off the Pirell Valley on Monday and Sunday and sunrise seemed to support their theory. Therefore, some people think that these two scientists will be complacent because of the two earthquakes this week. However, at least one of them is not. Leon Knopoff, a University of California Los Angeles geophysicist, said: "These two
