上海地震台阵标定及结果分析

RESULT ANALYSIS AND CALIBRATION FOR SHANGHAI ARRAY

阐述了台阵的地震定位原理和建立台阵标定数据库的必要性,说明了如何利用上海地震台网资料和上海地震台阵建成后的资料建立台阵标定数据库.最后,对上海台阵标定的结果进行了导致定位误差的横向速度变化的位置和范围的讨论.

The principle of locating epicenter in array and the necessity of establishing a calibrated database of array are expounded,and the establishing process of the calibrated database of Shanghai array which use seismic data of both Shanghai seismic network and Shanghai array is explained.At the end,the location and range of lateral velocity heterogencity which cause locating epicenter error in the data of Shanghai array are discussed.
