STUDY ON ABNORMITY CHARACTERISTICS OF CROSS-FAULT MEASUREMENT ON HEIZI FAULT
Jing Jiang · Northwestern Seismological Journal · 2002
Cross fault measurements data in 28 years of Heizi deformation station is studied by multinomial drafting ?annual extremum difference?speed?fault relatively minim displacement analysis. The results indicats that annual variation aberrance?speed quicken?annual extremum difference exceeding and fault relatively minim displacement evidently increasing are abnormality characteristics of medium strong earthquake in Heizi area (R=100 km).
