| description | Remote sensing and aerial photography techniques have been applied in a study of the Khlong Marui Fault in Surat
Thani and Phang Nga provinces of southern Thailand. Several faults are recognized in the region, trending mainly NE–SW. The
common 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 NE–SW Khao Panom
segment of the Khlong Marui Fault was conducted to identify and date faulting events. Two events with magnitude (Mw) 6.9
were observed at the Ban Pak Dan trench site, and OSL dating indicate late Quaternary faulting events from 20,000 ±1,500 years
ago; and from 14,500 ±1,000 years ago. The maximum slip rate is estimated to be 0.25–0.50 mm/yr, and the recurrence interval
of seismic events is between 1,000 and 2,000 years. |
