“The total population exposed to tsunami would be close to 14 million but they will not be affected the same time. It would depend on where the tsunami would occur,” Phivolcs chief Renato Solidum Jr. said.
Batay sa pagtatasa ng hazard ng Philvolcs at simulation sa Pilipinas, ang madaling kapitan ng populasyon sa NCR ay halos 2.4 milyon. Sinundan ito ng Rehiyon VII na may 1.6 milyon, ang Rehiyon VI na may 1.2 milyon at ang Rehiyon IV-1 na may humigit-kumulang na 1 milyon.
“Tsunamis in the Philippines can move very fast simply because the trenches are closer to our shoreline. Because of this restriction, we need to be sure that people are ready so that if ever there are signs to a possible tsunami, they need to react right away,” said Solidum.
Naging panauhing tagapagsalita si Solidum sa World Tsunami Awcious Day InfoSentro sa PHIVOLCS virtual press conference noong Huwebes kung saan tinalakay niya ang kahalagahan ng paggamit ng agham, teknolohiya, at mga makabagong ideya sa pagtulong sa mga pamayanan na maghanda para sa mga tsunami.
“The World Tsunami Awareness Day is a very important initiative globally to educate the public about the hazards of tsunami, but more importantly, how to prepare for it,” said Solidum.
Sinabi niya na maraming mga pamayanan ang kailangang sanayin upang maghanda para sa sakuna.
“This preparedness in some towns in eastern Philippines was tested when super typhoon Yolanda came,” he said.
Bago ang Yolanda, na ang bagyo ay nag-iwan ng 6,000 katao ang namatay, ang Phivolcs ay paikot sa silangan ng Pilipinas dahil maraming bayan sa baybayin doon ang nahantad sa banta ng isang malaking tsunami.
“Tsunami and storm surges are very similar. But storm surges, when you respond to it, you also have to worry about the strong winds,” he said.
Ang pandemya ng COVID-19 ay isa pang sagabal para sa kanila dahil hindi sila maaaring bumaba sa mga pamayanan upang makausap ang mga tao.
Gayunpaman, ang pandemya ay nagresulta sa maraming mga tao na talagang nakikinig sa kanila sa tulong ng mga platform ng social media.
“We reach more people in terms of information campaign. We hope local government disaster mangers would be able to do now the actual preparedness at the community level,” he said.
Pag-unawa sa mga tsunami
Ang mga tsunami ay maaaring maliit o malalaking alon na nabuo ng isang kaganapan sa lindol, pagguho ng lupa sa ilalim ng dagat, aktibidad ng bulkan, o epekto ng bulalakaw.
“It can drown people, devastate agricultural land near the shore. This would carry big things like ships and boulders that could impact people and destroy houses,” he said.
Noong 1976, isang lakas na 8.1 na lindol sa Moro Gulf ang nag-trigger ng isang tsunami na kasing taas ng 9 metro. Sinabi ni Solidum na ang unang alon ay dumating sa baybayin sa loob ng 2 hanggang 5 minuto pagkatapos ng temblor at nagwasak sa timog-kanlurang Mindanao.
“In 1994, a magnitude 7.4 earthquake occurred in Mindoro and most likely triggered a submarine landslide that caused a tsunami 5 minutes after the earthquake and the height of the tsunami was as high as 8 meters,” he said.
Ang mga trenches at faults ay dalawang mga generator ng lindol na maaaring makabuo ng mga tsunami, aniya.
“We have a lot of faults and trenches that generate tsunamis that is why both the eastern and western shorelines of the country are prone to large tsunamis and those in the middle, the inland coast, can still be affected by smaller tsunami waves because of fault movement or submarine landslides,” he said.
Hinimok niya ang publiko na alalahanin ang mga palatandaan na “Shake, Drop, and Roar” ng isang paparating na tsunami at agad na maghanap ng mas mataas o mas ligtas na lugar.
“Shake” is when a strong quake is experienced. “Drop” is when seawater is observed to be receding or dropping, and “roar” is the sound of an oncoming wave.
“Our country is prone to various hazards. We have seen the devastation of super typhoon Rolly and its impact on houses because of strong winds, the flooding, and the lahar in many places,” aniya.
“We need to make sure that we work together to overcome this. But most importantly, better if we are most prepared. We have science, technology, and innovation from DOST that can help in preparedness and disaster risk reduction. We need to use it but we need to share this information to the communities and the public.”
