Abstract | Remote sensing and aerial photography techniques have been applied in a study of the Khlong Marui Fault in SuratThani and Phang Nga provinces of southern Thailand. Several faults are recognized in the region, trending mainly NESW. Thecommon geomorphological features associated with the Khlong Marui Fault include fault scarps, triangular facets, offset streams,shutter ridges, hot springs, and linear valleys. Paleoseismological trenching at Ban Pak Dan across the NESW Khao Panomsegment of the Khlong Marui Fault was conducted to identify and date faulting events. Two events with magnitude (Mw) 6.9were observed at the Ban Pak Dan trench site, and OSL dating indicate late Quaternary faulting events from 20,000 ?1,500 yearsago; and from 14,500 ?1,000 years ago. The maximum slip rate is estimated to be 0.250.50 mm/yr, and the recurrence intervalof seismic events is between 1,000 and 2,000 years. |
