Tsunami alert
The Pacific Tsunami Warning Center (PTWC) issued a tsunami alert in the Philippines, Indonesia, Taiwan, Japan, Guam, the Northern Marianas and Papua New Guinea as soon as the earthquake was detected.
The PTWC lifted the alert two hours after the quake struck.
The PTWC said that based on sea level readings, the earthquake generated a tsunami.
“This tsunami may have been destructive along coastlines of the region near the earthquake epicenter,” the center said. “This center will continue to monitor sea level gauges nearest the region and report of any additional tsunami wave activity.”
The PTWC said that “when no major waves are observed for two hours after the estimated time of arrival or damaging waves have not occurred for at least two hours then local authorities can assume the threat is passed.”
At 9 p.m., Phivolcs issued a tsunami alert level 3 in coastal areas fronting the Pacific Ocean, particularly the provinces of Northern Samar, Eastern Samar, Leyte, Southern Leyte, Surigao del Norte and Surigao del Sur.
Interior and Local Government Secretary Mar Roxas announced over microblogging site Twitter that the tsunami warning alert was lifted at 12:10 a.m. Saturday.
Phivolcs chief Renato Solidum said that thetsunami warning was supposed to have been lifted at 10:47 p.m. or two hours after the earthquake, but they decided to extend it after detecting tsunamis as high as 19 centimeters in Surigao provinces.
Solidum said that there were no reported damages from the tsunamis as of midnight.
Ramos said that local government units in provinces covered by the tsunami warning alert were able to immediately evacuate residents living along coastal areas.
Solidum said that the hundreds of families that evacuated can already return to their homes.
“Iyong mga nagsilikas ay puwde nang bumalik. Tingnan nila ang mga babalikang bahay ay ‘di nasira.. Kailangan tingnan at i-assist ang mga lumikas,” Solidum announced in a press briefing after lifting the tsunami alert. – with AP
