APPLICATION OF TWO AND THREE DIMENSIONAL HIGH-DENSITY ELECTRICAL EXPLORATION ON THE HUGE DEFORMATION ANOMALY DETEMINATION OF SHORT-LINE LEVELING IN LONGCI STATIOM, LINFEN

The huge deformation occurred in Longci short-line leveling observation point Bm 3 on January 7, 2010 in Linfen central earthquake station, the daily subsidence amounted to more than 10 mm.In order to identify the deformation mechanism, Shanxi Province Earthquake Engineering Investigation Institute carried out the seismic geological survey around the Bm 3 point by using two and three dimensional high-density electrical exploration to detect the buried fault, and analyze the geological environment and the causes of huge deformation to provide a basis for earthquake forecast.
