00:00Pagtaas sa Alert Level 3 ng Bulcang Mayon at update sa aktividad ng Bulcang Halaon

00:06ating aalamin kasama si PHIVOX Director Dr. Teresito Bakulcol.

00:11Dr. Bakulcol, magandang tanghali po.

00:14Yes ma'am, magandang tanghali din po sa inyo and happy new year.

00:18Sir, ano ang mga indicators na naging basehan ang PHIVOX sa mabilis na pag-angat

00:22ng alert status itong mayon mula Alert Level 2 to Alert Level 3

00:26sa loob lamang ng limang araw?

00:30Okay, so kahapon inakit natin yung Alert Level from 2 to 3

00:34dahil yung activity sa summit ay hindi na lang under the rest.

00:39May tuloy-tuloy na eruptive process.

00:42So nagsimula ito sa paglaki ng lava dome.

00:44Ito yung manapot at makapal na lava na dahan-dahang naipon sa summit ng vulkan.

00:50So dahil patuloy ang paglaki ng dome,

00:53ibig sabihin may bagong lava na lumalabas at nadadagdag sa ibabaw nito.

00:57So kahit mabagal at hindi explosive,

01:00eruption pa rin ito, taawag natin itong lava extrusion.

01:03So habang lumalak yung dome,

01:06nagiging unstable ito,

01:07kaya madalas ang pag-uho

01:09at pag-produce ng maraming rockfall events.

01:12Since November, ay tuloy-tuloy ito,

01:15pero biglang dumami ito on the later part of December,

01:18lalo na between December 31 and January 1,

01:21na umabot ng 47 rockfall events.

01:23Kaya ito was last January 1 na tinaas natin yung Alert Level from 1 to 2.

01:28Now, pagdating naman ng January 5 to 6,

01:32umabot ito ng 85, halos doble.

01:34So isa ito sa mga dahilan kung bakit tinaas natin from 2 to 3.

01:38And noong gabi ng January 5,

01:42may na-observe tayong incandescent rockfall.

01:45So ibig sabihin ito, mainit at may bagong labas.

01:49Bagong labas yung gumuguho.

01:51So hindi lang lumang bato na nasa taas yung bumagsak

01:55dahil sa gravity,

01:57ito ay bago dahil mainit pa

02:00and nakikita natin glowing.

02:02And kahapon, January 6,

02:06ay may mas malalaki pang collapse

02:08na nag-generate ng limang pyroplastic density currents.

02:12Ito yung fast-moving mixture of hot rocks,

02:16gases, and ash

02:17na bumababa sa bunga gali

02:19na umabot ng dalawang kilometro mula sa bunga ng vulkan.

02:23So itong PDC,

02:25itong incandescent rockfalls

02:27ay malinaw na evidence

02:28na may aktibong nilalabas na lava

02:30at may nagaganap na eruption.

02:32Kaya tinaas natin sa alert level 3.

02:35Director,

02:36binanggit hindi ng feedbacks kapon.

02:38Ito, kailangan,

02:39daan-daanin ko ito.

02:40Ang very slow extrusion of shallow digas magma.

02:44Amari nyo po bang ipaliwanan ko

02:46ano po ito?

02:47Kagaya na sa katulad ko.

02:49At bakit hindi kasi ito

02:51ng isang effusive magmatic eruption?

02:55Okay, so ang ibig sabihin lang nito

02:57ay dahan-daan lumalabas ang magma o lava

02:59sa bungangan ng vulkan.

03:01At dahil ito ay shallow at digas,

03:03mas kaunti ang gas,

03:05kaya hindi ito explosive.

03:07So kahit babagal at walang malakas na pagsabog,

03:11eruption pa dito

03:11since may aktual na paglabas ng lava

03:14sa ibabaw at patuloy pa rin

03:17ang pagbubuo ng lava dome.

03:19Sir, kaugnay nung naitalang lava dome collapse

03:22at pyroclastic density currents sa Bungagali,

03:25gaano kalaki yung possibility na maulit

03:27o lumawak pa yung ganitong aktividad

03:29sa mga susunod na araw?

03:30Tsaka kailan po ba yung sumabog itong

03:33vulkan mayo na talagang malakas na malakas?

03:36Okay, so as long as there is

03:38continuous lava exclusion and dome growth,

03:42mataas pa rin ang possibility

03:43na maulit ito.

03:45Habang lumalaki at nag-unstable ang lava dome,

03:48mas tumataas ang chance ng paguho

03:50at maaari rin itong mag-resulta

03:52sa mas madalas at mas malalaki pang

03:54pyroclastic density currents

03:56na posibleng umabot pa sa mas malalayang bahagi

03:58ng ating mga galis.

03:59Now, yung tanong kung kailan ito

04:02last na malakas na malakas na nag-erupt,

04:05yung worst case scenario

04:07would be yung 1814 eruption

04:09kung saan yung kagsawa charts,

04:14kung nakapasyal tayo sa Ligaspi,

04:17yung kagsawa charts ay natabunan.

04:19So, that was the 1814 eruption.

04:25Director, eto na lang.

04:26Sa kasalukuyan sitwasyon,

04:28alin sa mga nabanggit natin kanina

04:29ang kinuturing natin na pinang mataas

04:31ang panganib at bakit?

04:35So, ngayon, ang lava dome collapse

04:37na pwede mag-resulta sa pyroclastic density currents

04:40ang kinukonsider natin na mas pinakapanganib

04:44dahil ang mga ito ay biglaan,

04:47mabilis, at napakainit.

04:49So, yung pyroclastic density currents

04:51can incinerate everything along their path

04:54kasama na rito yung vegetation,

04:56buildings, pati na rin yung mga tao.

05:00Dr. Bacolcol, ayon sa datos,

05:02364 rockfall incidents na yung naitala

05:05mula New Year's Day hanggang kahapon.

05:07Ano yung ipinapahiwatig na biglaang

05:09pagdami ng rockfalls?

05:10Kaugnay ng bilis naman ng lava dome growth

05:13na sinasabi niyo po kanina?

05:14Tsaka, ano po yung latest ngayon

05:15sa rockfall incidents?

05:19Okay, so,

05:20ang biglang pagdami ng rockfalls natin,

05:23this is an indication,

05:24this is indicative that the lava dome

05:27is very much active.

05:28And, posibleng bumibilis ang paglaki nito.

05:32Kaya, naging mas unstable ito

05:33at mas madalas ang pagguho.

05:37Another important point ay

05:39yung na-observe natin na incandescent rockfalls

05:41itong nabangit po kanina,

05:43ibig sabihin,

05:43mainit at bagong labas na lava

05:45ang nag-collapse.

05:47Now, patuloy pa rin

05:47ang pagdami ng rockfall events natin

05:49and, in fact,

05:50for the past 24 hours,

05:51nakapagtala tayo ng 131 rockfall events.

05:55So, 24 hours lang yun,

05:56131 rockfall events.

05:58Mas marami ito

05:59kesa noong January 5 to 6

06:00na 85 lamang

06:02when we raise it to alert level 3.

06:03Rektor, binanggit ang inflation

06:08ng eastern and south-eastern slopes

06:10ng mayon mula po noong Hulyo 2024.

06:12Paano ito nakakapekto

06:13sa kasulkuyang aktibidad ng bulkan

06:15at sa mga posibilidad

06:16na mas mapanganib na pagsabog?

06:21Yung inflation ay indicator yan

06:23na may patuloy na pag-iipon

06:25at pag-akyat ng magma

06:26sa ilalim ng mayon.

06:28Ito ang dahilan kung bakit ngayon

06:30ay may lava dome growth

06:31and lava extrusion

06:33sa bunganga ng bulkan.

06:35Kapag nagpatuloy pa ito

06:37ang pag-iipon ng magma,

06:39tataas yung presyo

06:40at posibleng lalala pa

06:41at mas pangalim ito.

06:43This may lead to

06:44an explosive eruption.

06:46Sir, sa rekomendasyon

06:48na mandatory evacuation

06:50sa loob ng 6-kilometer

06:51permanent danger zone,

06:53may nakikita po ba

06:54ang FIVOX na senyales

06:55na maaari pang palawakin

06:57yung danger zone

06:58kung magpapatuloy

06:59ang aktibidad ng bulkan?

07:01So, at alert level 3,

07:04we maintain

07:04the 6-kilometer

07:05permanent danger zone

07:06but if you raise it

07:07to alert level 4

07:08which means

07:10na may indicators

07:11of explosive eruption,

07:13we may extend

07:13the danger zone

07:14beyond the 6 kilometers.

07:15But right now,

07:16since alert level 3,

07:17maintain pa rin natin

07:18yung 6-kilometer

07:19permanent danger zone.

07:21Bilang follow-up doon,

07:22Director, ano yung mga senyales

07:24na binabantayan nyo

07:24sa FIVOX

07:25na maaaring mag-trigger

07:26ng pagtaas ng alert level

07:27sa level 4

07:28or sa level 5?

07:29Huwag na masana.

07:30Okay, so

07:32again,

07:33huwag naman sana

07:33but binabantayan natin

07:35yung mga parameters

07:36tulad ng

07:36biglaang pagtaas

07:38o di kayo biglang

07:38pagbaba

07:39o kabaliktara naman

07:41biglang pagbaba

07:41ng SO2

07:42kasi kapag biglang

07:44tumaas yan

07:45biglang abrupt

07:47na pagbaba

07:47ibig sabihin

07:47natatabunan

07:48yung

07:49yung kunduit

07:50ng vulkan

07:51and kapag

07:52nagkaroon ng

07:52overpressure

07:53pwede itong sumabog

07:55ng malakas.

07:56Tinitingnan din natin

07:57yung sustained increase

07:58in mass flux

07:59meaning

07:59kapag may nakita tayong

08:01mas mahahabang

08:02lava flows

08:02kapag naging

08:04mas madalas

08:04at mas malalaki pang

08:05pyrocast density currents

08:07and kapag

08:08nagakita tayo

08:08ng lava fountaining

08:09isa yan sa mga

08:10mga indicators

08:12din natin

08:13and kapag

08:14dumadami yung

08:15volcanic earthquakes

08:15natin

08:16tinitingnan din natin yan

08:19right now

08:19for the past

08:20two days

08:21wala ni isang

08:22volcanic earthquake

08:22po tayong naitala

08:23and kapag

08:24meron ng minor explosion

08:25so yun yung

08:26tinitingnan natin

08:27bago natin itaas

08:28to alert level 4.

08:30Doc, kung ikukumpara

08:31naman sa huling

08:31alert level 3 status

08:33ng mayon noong

08:34June 2023

08:35ano yung mga
