Inaapula ng mga bumbero ang sunog sa isang gusali bilang bahagi ng nationwide simultaneous drill na isinagawa ng NDRRMC sa Roxas Boulevard kahapon, Hulyo 2, 2014 (UNTV News)
MANILA, Philippines — Naglabasan ang mga tao sa isang gusali sa Roxas Boulevard pasado alas-9:30 kahapon ng umaga, Miyerkules, matapos makarinig ng sirena.
Sa kuha ng UNTV drone, tila may sunog sa corporate building ng PAGCOR na katapat lang ng US embassy. Ilang minuto pa ay nagdatingan na rin ang iba pang bumbero upang apulain ang sunog.
Dumating din ang mga rescue unit mula sa iba’t-ibang lugar ng Metro Manila upang bigyang first aid ang mga sugatang empleyado.
Ilan lamang ang mga senaryong ito sa mga posibleng mangyari kung sakaling gagalaw ang west valley fault.
Bahagi ito ng earthquake drill na isinagawa ng National Disaster Risk Reduction and Management Council (NDRRMC) sa iba’t-ibang lugar sa bansa bilang paghahanda sa lindol.
Ayon sa Philippine Institute of Volcanology and Seismology o PHIVOLCS, posible gumalaw ang west valley fault na may 7.2 magnitude na lindol na katumbas ng intensity 8 na lindol sa Metro Manila. Huling gumalaw ang west valley fault 356 years na ang nakalilipas.
“Parang sinasabi lang, in our lifetime baka gumalaw ito. So ang issue is dapat maghanda tayo at hindi tayo maunahan na mangyari man ang lindol na ito”, pahayag ni PHIVOLCS Director Renato Solidum.
Ayon sa PHIVOLCS, kung hindi mapaghahandaan ay malalagay sa panganib ang may 31 libong buhay sa Metro Manila lalo na kung mangyayari ito sa gabi.
Samantala, nag-akyatan naman ang mga tao sa isa pang building sa Roxas Boulevard matapos na tumunog at marinig ang bell. Hudyat ito ng paparating na tsunami mula sa Manila Bay. Bahagi rin ito ng drill kung gagalaw naman ang Manila Trench.
Sa pag-aaral ng PHIVOLCS, kung gagalaw ang Manila Trench, maaari itong maglabas ng 8.2 magnitude na lindol at magdulot ng hanggang 3 metrong tsunami at apawan ang Roxas Boulevard at posibleng abutin ang mga buiding sa kahabaan ng Roxas Boulevard.
Ang haba ng Manila Trench ay mula sa Mindoro hanggang sa Taiwan.
Sa pamamagitan ng drill na ito ay masusukat ng pamahalaan kung gaano kahanda ang isang lugar sakaling magkaroon ng sakuna.
Kaya’t pakiusap naman ng NDRRMC, sana’y huwag gawing biro ng mga tao ang drill sa lugar na pagdaraosan nito.
“Sa totoong insidente, segundo po ang pinaguusapan natin diyan, ang binibilang natin. Kung tayo po ay parang namamasyal sa buwan nung sinasabing ang senaryo ay guguho na yung building ay pagdating ng araw po wala po tayong ibang masisi kundi yung sarili natin”, saad ni NDRRMC Executive Director Usec. Alexander Pama.
Suhestyon naman ng PHIVOLCS na magsagawa rin ng paghahanda sa bawat tahanan.
“Gumawa ng evacuation plan sa bahay at saan sila mag-evacuate sa komunidad at isubmit sa teacher para ma-check kung tama kasi ngayon handa tayo sa eskwelahan pero hindi sa bahay”, ani Solidum. (Rey Pelayo, UNTV News)
The volcanic activity in Taal continues to wane, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
However, it is still not enough basis to lower the alert level in the region.
Phivolcs’ findings show that the amount of sulfur oxide or ashes emitted by Taal Volcano decreased from 4,000 tonnes per day to 153 tonnes. There is also a decrease in the frequency of volcanic earthquakes.
“Itong mga earthquakes na ito ay unti-unti na silang nag-diminish pati iyong mga low frequency events pero hindi ibig sabihin ay kampante na tayo (These earthquakes are slowly diminishing, even the low-frequency events. But this does not mean we can be lax about it),” according to Phivolcs Volcano Monitoring and Eruption Prediction Division (VMEPD) Chief Ma. Antonia Bornas.
The agency said the decreased emission can mean the ashes are blocked by the hardened magma in the volcano’s crater. This could also mean a high activity of magma inside the volcano which can prompt a huge eruption at any time.
If the waning of volcanic activity continues in the succeeding days, Phivolcs said they might lower the alert in the Taal region to level 3.
“Ibababa po naman po natin ang alert level after masiguro po natin ang probabilities for an eruption ay mababa na (We will lower the alert level after we assure that all probabilities of eruption are low),” Bornas added.
However, residents are still not allowed to return to their homes even if alert level 3 has been announced by Phivolcs.—AAC (with reports from Dante Amento)
MANILA, Philippines – Intense volcanic activities are still being recorded around Taal Volcano while it continues to spew white ash.
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), these are signs that the volcano is still an element of danger.
Ground shaking has become frequent as PHIVOLCS recorded more than 700 tremors on Sunday (January 19) alone.
Fissures are also becoming more and more visible in different areas, which PHIVOLCS explained, are signs of rising magma.
“Baka lang kasi akala ng mga tao humuhupa lang, pero sa indikasyon na dumadami ang gas, diyan natin pinapakita maliban sa lindol at iyong pamamaga ng bulkan na mayroong laman doon sa ilalim (People might think it is calming down but increasing gas emission, aside from tremors and the swelling of the volcano ground are indications that something is underneath),” PHIVOLCS OIC Renato Solidum explained.
“Baka iyon ang maging dahilan ng mga biglaang pagsabog kasi open system na iyong volcano (Those might cause the eruption because the volcano is already an open system),” he added.
Also, Taal Volcano is still producing kilometers tall ash pillars and a high level of sulfur dioxide, about 1,000 tons per day, similar to the amount that Mayon Volcano produced before its major eruption in the past.
PHIVOLCS noted that said amount can mean danger.
“Mataas po iyan. Kung naaalala ninyo po sa Mayon, iyong ganiyang values ay pumuputok ang bulkan (That’s high. If you remember, Mayon showed similar values when it erupted),” noted PHIVOLCS Chief of Volcano Monitoring and Eruption Prediction Division (VMEPD) Ma. Antonia Bornas.
“So, may nagde-degas na shallow magma. So, anytime, kapag mababaw ang magma, maaari po itong pumutok na wala po tayong masyadong paunang babala (That means shallow magma is degassing. So when magma becomes shallow, it might erupt without prior warning),” he added.
State weather agency PAGASA explained that areas in the western or southern section of the volcano might be affected by heavy ashfall should Taal Volcano produce ash pillars of about three kilometers tall.
Also, based on the agency’s wind forecast, volcanic ash might reach several areas in Cavite should the volcano produce ash column higher than three kilometers.
However, should a major explosion occur and the volcano emitted ash pillar higher than five kilometers, the ash fall might affect Metro Manila, Laguna, Rizal and parts of Northern Quezon.
Solidum confirmed that the strongest ground shaking recorded so far was felt in Mabini, Batangas, a magnitude 4.6 earthquake at around 8:59 p.m. on Sunday (January 19).
Solidum said the tremor was caused by the movement of the fault.
He said the fault last moved in April 2017 and it was again activated due to the eruption of the Taal volcano.
PHIVOLCS reiterates its call to residents to stay away from the 14-kilometer danger zone while they are still observing the state of Taal Volcano.
Should volcanic activities wane within two weeks, PHIVOLCS said they might decide to downgrade the alert level over Taal volcano island. MNP (with details from Asher Cadapan Jr.)
MANILA, Philippines – Over a week since Taal Volcano began its eruptive activity, danger still remains according to experts.
In fact, a total of 787 earthquakes have been recorded in the volcano island on Saturday (January 18) alone, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
This frequency of ground shaking is double the number of all volcanic earthquakes recorded in the previous six days of Taal’s volcanic activity.
Over the weekend, more than 200 tremors were recorded within the range of magnitude 1.2 and 4.1, the PHIVOLCS said and on Sunday evening (January 19), the strongest shaking – magnitude 4.2 earthquake – was felt in Mabini, Batangas.
The volcano institute have also observed that Taal is producing about one-kilometer high white ash pillar and sulfur dioxide of around 1,442 tons each day.
Because of these observations, PHIVOLCS cannot just lift or downgrade Alert Level 4 that is currently in effect around the volcano island because the possibility of a massive explosive eruption remains high within hours or days.
Thus, PHIVOLCS strongly appeals for understanding and more patience from residents and reminds them not to return yet to their villages especially those within the 14-km danger zone.
