PHUKET, 18 April 2012 (NNT) – A geologist has indicated that the recent tremors in Phuket province had been sparked by last week’s 8.6-magnitude Sumatra quake, while also pointing out that the two major fault lines in the South of Thailand must be monitored closely.
The Environmental Geology and Geohazard Bureau Director Lertsin Raksaskulwong said that the 4.3-magnitude eartquake in Phuket’s Thalang district originated from small branches of the Ranong and Khlong Marui fault lines. The movement of the two active fault lines was caused by the 8.6-magnitude earthquake which took place in Indonesia’s Sumatra Island on 11 April. According to the geologist, a series of small to medium magnitude tremors, measured under 6 on the Richter scale, will continue to shake southern Thailand.
Two fault lines are situated in the South of Thailand, namely the Ranong fault line spanning across the provinces of Ranong, Chumphon, Prachuap Khiri Khan and Phang Nga, and the Khlong Marui fault line, which runs across Surat Thani, Krabi and Phang Nga.
Following the Phuket earthquake on Monday, almost a dozen aftershocks were detected in Phuket. The latest one, measured at about 3.2, took place around 4am this morning.
