KUALA TERENGGANU: It was the third time in 35 years that Tasik Kenyir had experienced tremors, said Terengganu Menteri Besar Datuk Seri Ahmad Razif Abdul Rahman.
He said the first was in 1980 with a 4.6 Richter scale magnitude earthquake followed by a 2.6 magnitude quake in 2010.
"This (the tremors) occurrence, I am told, is a result of a release of tectonic gas along the quake-prone line.
"Tenaga Nasional Berhad also informed me that there was no danger to its Sultan Mahmud Hydroelectric power station operating at the lake," he told newsmen at the pre-launch of the Beautiful Terengganu carnival at Wisma Darul Iman.
Razif was responding to Tuesday's 2.7 magnitude tremor, with its epicentre 16km sout-west of Kuala Berang, that rocked nine villages at 9.25pm as reported by the Malaysian Metrological Department.
The villages affected were Kampung Jenagor, Pueh, Gaung, Kepah, Dusun, Batu Belah and Kuala Ping.
