MANILA, Philippines – Want to know potential hazards within your area?
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) on Tuesday (July 16) launched a web application dubbed as ‘Hazard Hunter’ which provides the public with information on the possible dangers that may happen in a specific area like earthquake, flood or even volcanic eruption.
‘Hazard Hunter’ is a web-based application that can be accessed on desktop, laptop or in smart phones.
A welcome message will lead you to the Hazard Hunter official page.
You will be asked to proceed until you see the full map of the Philippines.
Click on the menu bar then several options on the type of hazards that may be present in your area will appear – seismic for earthquakes, volcanic for volcanoes and hydro-meteorological for flood and storm-related hazards.
Click on the type of hazard then select an area by pointing the cursor to the place of inquiry on the map.
Double click on the area of choice.
The system will immediately load the results that will flash on the right side of the screen.
For instance, Baseco compound in Manila has a population of about 60,000 people.
Based on the app’s reading, Baseco is about 12 kilometers away from the West Valley Fault.
Residents in Baseco may feel ground shaking of up to intensity 8 once the West Valley Fault moves in an event called the Big One.
The area is prone to liquefaction and could suffer from up to four-meter-high tsunami as it is near Manila Bay.
Based on the app, Baseco is less likely to be affected if ever the nearest active volcano, Mount Taal in Batangas, erupts.
Taal Lake is about 58 kilometers away from Baseco.
Baseco is a flood-prone area and floodwater can go as high as two meters and can take up to three days to subside.
During the onset of a severe tropical cyclone, the area could suffer from storm surge as high as 4 meters.
But there is no possibility of a landslide in the area.
The app also has detailed recommendations or suggestions for a plan of action during a specific hazard.
Science and Technology Undersecretary and PHIVOLCS OIC Renato Solidum believes ‘Hazard Hunter’ will enable the public to prepare and plan ahead of a natural disaster.
Government agencies will also be guided for appropriate actions to be taken to minimize or prevent the loss of lives and damage to properties.
“Hindi naman masama na may hazards diyan. What is important is that the hazard is recognized so that the developer can develop approaches to lessen the impact, to mitigate the possible impact,” Solidum noted.
Solidum said even his own house sits on a location that is hazard-prone but recognizing the dangers enabled him to plan for his and his family’s protection.
“Tinaasan ko yung bahay. Ginawa kong three floors para hindi ako mamatay sa baha (What I did was I elevated my house. I made it into three floors to keep me safe from the flood),” he said.
“Inayos ko yung foundation ng building para sa shaking ng liquefaction. So mga ganung klaseng real life application magagamit (ang Hazard Hunter) (I aligned the foundation of the building in case of shaking during liquefaction. During those real-life applications, [Hazard Hunter] can be useful),” he added.
Before the end of the year, PHIVOLCS plans to launch the mobile version of the website. – with details from Rey Pelayo
MANILA, Philippines — Earthquake drills have been suspended since the outbreak of coronavirus disease (COVID-19) occupied the government in the past months.
The National Risk Reduction and Management Council (NDRRMC) acknowledges the risk of COVID-19 transmission if people engage in drills.
“Delikado pa kasi iyan ngayong may pandemya pa, (That is risky given that we are in the midst of a pandemic),” explained the agency’s spokesperson Mark Timbal.
Timbal said they can still resume as soon as a vaccine for COVID-19 is discovered.
“I believe that we will resume the drills once both an effective treatment program as well as an immunization/vaccine is already available,” he added.
Despite the suspension of the drills, the agency said the public gets the information it needs through the local government units through constant information campaigns about disasters and diseases, specifically health protocols in evacuation centers, wearing face mask, using personal protective equipment and practicing social distancing.
The NDRRMC also conducts online training for that matter.
But for the Philippine Institute of Volcanology and Seismology (PHIVOLCS), it is still important to always prepare for potential disasters like earthquakes, typhoons and serious floodings even in the midst of a pandemic.
Science and Technology Undersecretary and PHIVOLCS OIC Renator Solidum assured that the agency is constantly conducting online seminars among LGUs and assessing the possible impact of disasters like earthquakes in their respective areas.
PHIVOLCS encourages every member of the family to discuss preparations amongst themselves as to what they will do in case of a serious earthquake like where they could possibly go to be safe.
Each family also needs to have an emergency kit in place complete with face masks, alcohol or sanitizer.
“In the past many large scale disasters minsan merong mga natataong mga pandemic. Mahirap iyon kung hindi handa sa pareho, [In the past, there were large scale disasters that happened along with a pandemic. It’s difficult to be in both situations unprepared,]” Solidum explained.
“We should prepared for both, not only for COVID-19 but also other possible large-scale hazards,” he added.
PHIVOLCS has created applications which can be checked for potential hazards in a specific area and these applications can be accessed through the Georisk Philippines website. MNP (with reports from Rey Pelayo)
MANILA, Philippines — Mount Kanlaon in Negros Island is one of the most active volcanoes in the country similar to Mt. Pinatubo in Zambales, Mt. Mayon in Albay, Mt. Bulusan in Sorsogon, and Mt. Hibok-Hibok in Camiguin Island.
Based on the observation of the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the volcano has recorded abnormal activities especially last Sunday (June 21) and Monday (June 22).
Earthquakes have been felt as the volcano spewed ashes.
Department of Science and Technology (DOST) Undersecretary and PHIVOLCS OIC Renato Solidum explained these activities may be attributed to an existing fault.
They are now observing if the tremors will move under the summit.
“Itong pagkilos ng fault ay posibleng sanhi dahil sa pag pressurize ng lugar sa Kanlaon volcano ng hydrothermal fluids o pagpapakulo ng tubig o di kaya ay mas malalim pang magmatic activity,” Solidum noted.
Most of the Kanlaon’s explosions were phreatic, the agency observed.
Based on studies of rock samples from the volcano, its last lava episode was in the early 1900’s.
In the 1996 eruption, three persons who went up the volcano died.
Usec. Solidum said Mt. Kanlaon is not comparable with the Taal Volcano when it comes to activities, though a major eruption is possible.
Alert Level 1 has been raised over Mt Kanlaon since March this year.
“Kung ang tanong mo ay mabilis yung escalation, wala tayong nakikitang ganung history sa Kanlaon based on record history (We didn’t have any record of rapid escalation based on Kanlaon’s record in history),” Solidum said.
“Pero yung posibilidad ng magkaroon ng mas malakas na eruption ay nandoon katulad ng Mayon Volcano; not Taal Volcano, hindi naman sila pareho ng setting (But there is the possibility of a major eruption like with Mount Mayon, but unlike Taal Volcano. Their settings are different),” he added.
PHIVOLCS warned that entering the four-kilometer permanent danger zone is strictly prohibited. MNP (with reports from Rey Pelayo)
Inihahanda na ng pamahalaan ng La Carlota City sa Negros Occidental ang disaster management plan na ipatutupad sakaling lumala ang ipinakikitang abnormalidad ng Mount Kanlaon.
Ayon kay La Carlota City Mayor Rex Jalando-on, nakapaloob sa kanilang plano ang pagtukoy sa mga barangay na lubos na maapektuhan at kailangang ilikas sakaling sumabog ang bulkan o kaya ay mas tumindi pa ang nararanasang pagyanig sa paligid ng bulkan.
Nakapaloob rin sa disaster management plan ang gagamiting logistics, transportation at available resources, pati na ang positioning ng food packs at mga lugar na maaaring gamiting temporary shelter ng mga ililikas na residente.
Tiniyak rin ni Jalando-on na mayroong P10 milyong quick response fund na maaaring gamitin ang lokal na pamahalaan.
Nagsasagawa na rin sila ng kampanya upang paalalahanan ang mga residente na maghanda at maging alerto sa gitna ng nararanasang pagyanig sa kanilang lungsod.
May gagawin ring drill upang malaman ng mga residente ang mga dapat gawin kapag nakaranas ng malakas na lindol o kaya ay sumabog ang bulkan.
Bahagya ring humina ang inilalabas na puting usok ng bulkan na umabot sa taas na 300 metro.
Iniulat rin ng PHIVOLCS ang patuloy na deflation sa ibabang bahagi ng bulkan at inflation o paglobo naman sa gitnang dalisdis na nangangahulugan umano ng hydrothermal o magmatic activity sa ilalim ng lupa.
Muli ring nagpa-alala ang ahensiya na nasa alert level 1 ang Mount Kanlaon na ang ibig sabihin ay nagpapakita ito ng abnormal na aktibidad at nasa “period of unrest.”
Naka-deklarang permanent danger zone ang four-kilometer radius ng bulkan at ipinagbabawal ang pagpasok rito ng mga tao.
Sakop naman ng eight-kilometer radius ng bulkan ang mga Barangay ng Ara-ala at Yubo kaya’t mahigpit itong binabantayan ng lokal na pamahalaan. – RRD (mula sa ulat ni Correspondent Lalaine Moreno)
