Ther… The publicized four-stage (long-term, middle-term, short-term, and im-minent) prediction of the M 7.3 1975 Haicheng, China, earthquake once generated worldwide fascination. Both before and after the Haicheng earthquake, 1975, and the Tangshan earthquake, 1976, in China, repeated levelling surveys had been carried out. Because of this correct prediction, many lives were saved. Further aiding the prediction, cats and other animals are also said to have acted strangely in the days leading up to the earthquake. This earthquake had an Ms magnitude of 7.5, which is associated with total destruction of infrastructure and property. On February 4, 1975, an earthquake measuring 7.3 on the Richter Scale rocked Haicheng, Liaoning province. The M 7.3 1975 Haicheng earthquake is the most widely cited "success" of earthquake prediction. Using arrival times from six local seismic stations, the foreshocks and mainshock were located relative to a master event. 01975-02-04February 4, 1975: 1975 Haicheng earthquake: No data Haicheng, Liaoning: 7.3 M S: 1,328: Many lives were saved as a result of evacuations ordered by seismologists who predicted the quake the day before.

Based on this principle, the foreshock sequence of the 1975 Haicheng earthquake withM S 7.3, was analysed backward. However, seismologists sent out warnings about this earthquake a day earlier and ordered evacuations. Haicheng had approximately one million residents at the time of the earthquake, which is kno the sience of earthquake prediction. Thousands of buildings collapsed and within minutes, the city was in ruins.

In this paper isoseismal map of this earthquake was drawn for these areas by sorting out and analyzing data systematically collected, furthermore, the characteristics of the earthquake damage were discussed. Introduction There was a change of gravity values before and after the Niigata earthquake of 1964 (Fujii, 1966). livestock and other animals, which increased before the quake. She is currently pursuing a masters degree in earth science. These surveys revealed some characteristics of the changes of 1. However subsequent efforts provide the breadth of coverage needed to gather the clues that would help Comments . in wells and animal behaviour led to the hope that community monitoring could It is stated clearly that the time-to-failure and magnitude of the mainshock can be predicted successfully if the coefficientr 2 attains to the maximum.

The political authorities therefore ordered various measures taken, including enforced evacuation of homes, construction of "simple outdoor structures", and showing of movies out-of-doors.
