Philippine Institute of Volcanology and Seismology (Phivolcs) allayed fears the magnitude 7.2 earthquake that struck Bohol province Tuesday morning would generate a “tsunami”, noting such scenario is unlikely.
Phivolcs Director Renato Solidum said in a televised press conference that as of this posting, 20 aftershocks had been reported in the area, however, Solidum said that “aftershocks will diminish with time.”
He said latest available data show the earthquake occurred on land, not offshore, so the tremor is incapable of generating a “tsunami”.
“We recorded at least 20 aftershocks,” Solidum said.
As of 10:00 a.m., the Phivolcs website reported the most powerful aftershock was at magnitude 4.3, at 9:37 a.m.
It was felt at Intensity IV in Tagbilaran City, though Phivolcs said no damage or aftershock was expected.
The Phivolcs director also emphasized for the people not to panic as the danger of possible “tsunami” was over since this commonly take place “five to ten minutes after a quake.”
The agency is studying if East Bohol Fault within Bohol Island generated the earthquake.
Tuesday’s earthquake struck two km south 16° east of Bohol’s second-class Carmen municipality at 8:12 a.m..
According to Phivolcs, the quake of tectonic origin occurred at a depth of 33 km.
“This magnitude-7.2 quake is powerful. It can cause damage,” Solidum said in a radio interview earlier.
The quake was felt in Cebu and parts of Negros Oriental, and even as far as Iligan City in Mindanao.
Solidum said their initial information showed the quake was also felt in parts of Mindanao such as Surigao and Iligan City.
“It is so powerful there is a possibility it could be felt 100 to 200 kms away,” he said. PNA
