1984年10月27日11时32分及11月1日2时42分,在川南泸县境内先后发生两次3.0级地震.这两次地震的微观震中分别为北纬28°55′东经105°15′及北纬28°56′东经105°42′.经宏观考察,地震叠加破坏较重的是泸县的宜定乡,同时还包括相邻的通滩区一带,其次有况场乡以及纳溪县的马岭乡等地,泸州市有感.震中在宜定,据泸州地震台资料,震源深度约2公里,震中烈度V~+～Ⅵ度.这次地震的震级较小,由于震源很浅,破坏较重,尤其突出的影响了当地的中、小学校正常行课,引起了县、市、省政府的重视.
At 11:32 on October 27, 1984 and 2:42 on November 1, two magnitude 3.0 earthquakes occurred successively in Lu County, southern Sichuan Province. The microseismic epicenters of these two earthquakes are respectively latitude 28 ° 55’N 105 ° 15 ’and latitude 28 ° 56’N 105 ° 42’E.After a macroscopic survey, the heavy damage caused by the earthquake superimposition is Yixing Township of Lu County, and also includes the adjacent Tongtan District, followed by Guochang Township and Nan According to the information of Luzhou Seismological Station, the depth of the epicenter is about 2 km, and the epicenter intensity is V ~ + ~ Ⅵ degrees. The magnitude of the earthquake is small because the focal point Very shallow, heavy damage, especially prominent local and primary schools affected the normal class, causing the county, city and provincial government attention.
