GEO-RESISTIVITY SURVEYS FOR FAULTS IDENTIFICATION IN GEOTECHNICAL DAMAGES AREA FROM YOGYAKARTA EARTHQUAKE OF MAY 27, 2006
The huge devastation of the earthquake of 6.3 MW scales in Yogyakarta and Central Java on May 27, 2006 caused widespread death and destruction to the heavily populated and relatively prosperous region. This paper presents geo-resistivity investigation to evaluate the faults location and its related geotechnical problems caused by Yogyakarta earthquake events. Geo-resistivity method was employed to map the underground fault lines in selected sites of the damaged area. The discontinuity of soil layers in fault locations were clearly found in the sub-surface depth around 6 to 30 m. It was also found that local liquefaction were found in several sites in which the water table was relatively shallow and close to the fault lines. Ground settlements and horizontal displacement were also observed in several sites where signs of liquefaction were found nearby. The result showed that the severe building damage were close to the fault lines where the local liquefaction and soil boiling were recognized as well.
