MANILA - The series of quakes that hit Batanes early Saturday morning is not expected to generate tsunamis around the northern islands, Phivolcs Director Renato Solidum said.
Two foreshocks with magnitudes 5.4 and 3.2 jolted the island between 4 and 5 a.m., before the 5.9-magnitude main shock struck around 7:38 a.m.
"Wala naman pong tsunami na maidudulot ito," Solidum told DZMM radio.
(This is not expected to trigger a tsunami.)
"Tectonic ang origin nito [dahil] may local faults ang paligid ng Batanes," he said.
(It is tectonic in origin because there are local faults surrounding Batanes.)
State seismologists expect more aftershocks to occur in the next few hours, Solidum said.
"Hindi natin inaalis na may mga susunod pang malakas. Ang rule of thumb, puwedeng 1 order of magnitude lower," he said.
(We are not discounting the possibility that the next quakes would be stronger. The rule of thumb is aftershocks should be 1 order of magnitude lower than the main shock.)
