地震预报非常重要的一环是短临预报,只有短临预报成功,前面的中长期预报才具有实际的价值。所以,研究短临预报成了当前急需的课题。本文的目的,就是对1978年5月19日凤仪地震的短临异常特征作讨论,以期能作为今后预报大理州南部五级以上地震的借鉴。 A very important part of earthquake prediction is short-term and short-term forecasts. Only short-term and short-term forecasts are successful, and the medium- and long-term forecasts in the preceding paragraphs are of real value. Therefore, the study of short-term forecast has become a much-needed issue. The purpose of this paper is to discuss the short-term anomaly characteristics of the Fengyei Earthquake on May 19, 1978 with a view to being able to serve as a reference for the future prediction of earthquakes of magnitude five or more in southern Dali Prefecture.
