FAR FIELD HORIZONTAL MICRO-DYNAMIC CRUSTAL DEFORMATIONS BEFORE AND AFTER INDONESIA Mw9.0 EARTHQUAKE
印尼9.0级地震前后远场水平地壳微动态变形

Using the data of GPS fiducial stations in China and IGS stations around the epicenter,we studied the horizontal micro-dynamic crustal deformations before and after Indonesia Mw9.0 earthquake in far field.The E component showed regional distinction changes before the earthquake.It was that the stations located in north-east from the epicenter moved east,controlled by pinching action,whereas,stations located in northwest from the epicenter moved west ward,effected by stretching force.It showed a characterist...
