MANILA, Philippines — Plano ng Department of Science and Technology (DOST) na magkaroon ng isang advisory system ukol sa storm surge.

Sa naturang panukala, magkakaroon ng tatlong uri at antas ng storm surge advisory na ilalabas 48-oras bago ang inaasahang pananalasa nito.

Itataas ang unang babala kung aabot sa dalawang metro ang taas ng storm surge sa apektadong lugar;

Storm surge advisory number 2 naman kung limang metro ang taas ng tubig, habang advisory number 3 naman ang ilalabas kung mahigit sa limang metro ang storm surge.

Inaasahang makukumpleto ang detalyadong mapa ng mga lugar na maaaring tamaan ng storm surge sa Setyembre o bago matapos ang taon.

Matatandaang bukod sa libu-libong nasawi, nag-iwan ng matinding pinsala ang storm surge sa Tacloban City at iba pang lugar na dinaanan ng Bagyong Yolanda noong nakaraang Nobyembre 2013. (UNTV News)

First PH-made train began operations in PNR

by Aileen Cerrudo   |   Posted on Monday, May 6th, 2019

The first Philippine-made hybrid electric train operated for the first time in the Philippine National Railways (PNR) on Monday (May 6) for its validation test.

READ: First PH-made train to operate this May

Liza Pertumen takes the PNR train everyday. From Laguna to Muntinlupa, she travels early at dawn to work as a laundry woman. The train ticket costs P20.

Riding the PNR is convenient, she said. It costs way less compared to the P200 fare and there is no traffic.

Liza will be one of the possible passengers of the first Philippine-made hybrid electric train once it officially begins operations.

The hybrid electric train took passengers for a free ride as part of its validation test that will last until May 28. It currently operates from Alabang to Calamba, Laguna station.

According to PNR Spokesperson Joseline Geronimo, in case the trains pass the validation test they will begin its revenue operation. Geronimo also said the hybrid electric train will also help in increasing the number of train sets in PNR.

“Makakadagdag siya sa aming magagamit dahil as of now medyo limited iyong aming number of train sets dahil iyong aming ine-expect na nga brand new trains ay dadating palang before the end of June, (As of now, we have a limited number of train sets so [the hybrid train] will help. Our expected new trains will be arriving before the end of June.)” he said.

The PNR management still hasn’t decided on the fare for the hybrid train.

The first Philippine-made hybrid electric train was made and designed by the engineers of the Department of Science and Technology (DOST). It has two power sources: battery and generator.

“It has two power sources so [iyong] pagiging hybrid niya nagiging more energy efficient siya and environment friendly kasi nagiging less ang fuel consumption natin and iyong gas emission less din (So its hybrid design is more energy efficient and environment-friendly. It has less fuel consumption and gas emission),” according to Engr. Pablo Acuin, project manager of DOST.

The hybrid train is also composed of five fully air-conditioned freight cars with CCTV. It took five years to make the train which is worth P120 million.

It can run from 60 to 80 kilometers and can accommodate up to 800 passengers per travel.(with reports from Joan Nano)

Segment of PH trench off Surigao del Norte coast may generate magnitude 8 earthquake – PHIVOLCS

by Marje Pelayo   |   Posted on Tuesday, April 30th, 2019

MANILA, Philippines – A series of small and moderate earthquakes has been recorded along the Philippine trench off the coast of Surigao del Norte.

On April 26, a magnitude 5.5 earthquake was recorded 70 kilometers southeast of General Luna on Siargao Island.

Department of Science and Technology (DOST) Undersecretary Renato Solidum said earthquake swarms may continue due to the subduction in the Philippine trench.

The official explained that an earthquake swarm is different from aftershocks.

“Ang aftershock kasi ay maliliit na paglindol pagkatapos ng isang talagang malakas na pagyanig, distict na malakas. Ang nangyayari kasi sa off shore ng Surigao del Norte may magnitude 5.5 pero may mga magnitude 5, 4 point plus. So hindi talaga isang lindol na malakas tapos puro maliliit na. (An aftershock is a small earthquake after a strong shaking, distinctively strong. What is happening off the shore of Surigao del Norte is that, there is magnitude 5.5 but there are magnitudes 5, 4 point plus. So it’s not a strong earthquake and the followed by small ones,)” the Director of the Philippine Institute of Volcanology and Seismology (PHIVOLCS) explained.

Recently, a series of earthquakes in the area has also been recorded but Usec. Solidum said the activities have gradually subsided.

PHIVOLCS monitors the area so that they can immediately warn the public for a possible tsunami if a strong tremor occurs.

Solidum said a strong earthquake might not happen but it was a long time ago since the agency recorded a strong movement in that segment of the Philippine trench.

“Posibleng mga class magnitude 8 earthquake ang pwedeng maidulot ng pagkilos sa Philippine trench at pwede itong mag-trigger ng tsunami na pwedeng makaapekto sa baybayin ng mga probinsyang nakaharap sa Pacific Ocean, (The Philippine Trench may cause class magnitude 8 earthquake and it may trigger Tsunami that may affect coastal areas facing the Pacific Ocean,) Solidum said.

The official said a tsunami might reach the nearest fault in a matter of minutes depending on the distance of the epicenter to the nearest coast.

Although no swarm was recorded in other segments of the Philippine trench like the Manila trench, Sulu-Negros trench, and Cotabato trench; they may generate a major quake.

The Manila trench may generate a magnitude 8.3 earthquake and tsunami with a height of 3.5 meters to 5.5 meters.

Areas facing the West Philippine Sea might be affected including the Manila Bay.

“Kung nasa dalampasigan sila o malapit, mapapansin nilang biglang bumaba ang tubig, mabilisan. At kung nandoon pa sila malapit sa dalampasigan, pwede silang makarinig ng kakaibang ugong at ito ay senyales na ang tsunami ay paparating na sa dalampasigan, (If they are in or near the coastal areas, they will notice the immediate or abnormal drop of seawater. And if they are near the coastline, they would hear a roaring sound and it is a sign that a tsunami is approaching,)” Solidum concluded. – Marje Pelayo (with reports from Rey Pelayo)

Filipino experts develop quake-proof desks for kindergarten students

Filipino experts have developed quake-proof desks for kindergarten students. It also serves as an earthquake warning system.

According to the released statement of the Department of Science and Technology (DOST), a group of researchers from the Philippine Normal University (PNU), De La Salle University, and Technological University of the Philippines, developed a high impact-proof automated study desk for preschool children.

They called it LAMESA or Life-Saving Automated Mesa to Endure Seismic Activity.

“LAMESA combines technology with capacity building in terms of knowledge and infrastructure to best address such probable disaster, particularly in educational institutions,” their statement reads.

The LAMESA desk measures 1.22 m in length, 0.69 m in width and 3.327 cm in tabletop thickness. It’s height is 0.57 m so that preschoolers can easily hide under the desk. Its table top is also made of steel and is coated with epoxy paint for durability.

There is also a storage bin with a sliding door for keeping lighting devices, food and water supplies for up to nine kindergarteners.

“LAMESA is equipped with an accelerometer, a device that senses motion, which feeds seismic measurements to a Wi-Fi-enabled microcontroller. This microcontroller then simultaneously triggers the actuator which causes the table top to fold 16 degrees upward,” the statement further reads.

PNU’s Dr. Marie Paz E. Morales, research team leader, said “[On] average, a strong earthquake that may cause debris lasts about 30 to 40 seconds. This means that LAMESA’s four-second response time provides ample time to shield children from debris during an earthquake.”

The researchers are continuing to make improvements to enhance LAMESA’s prototype design.

“We are [also] contemplating on using fiberglass instead. We also thought of using a wall sensor to manage a set of desks,” Dr. Morales adds.—Aileen Cerrudo
