Coastal communities near Subic Bay will soon achieve tsunami preparedness as the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in collaboration with the Advanced Science and Technology Institute (ASTI), agencies under the Department of Science and Technology (DOST), prepare for the installation of tsunami detection sensors at Sueste Point in Subic Bay within the territorial jurisdiction of Subic Bay Metropolitan Authority.

This initiative is part of the PHIVOLCS-ASTI project on tsunami warning and preparedness called “Establishment of a Cost-effective Local Tsunami Early Warning System for Selected High-risk Coastal Communities of the Philippines”, or TeWS, which is under the DOST-Grant-in-Aid (DOST-GIA) Project.

The Subic Bay tsunami detection sensors is TeWS’s next and final target for this phase under DOST-GIA following the placement of tsunami warning sirens in Mabacong and Sta. Rita Aplaya, the two pilot barangays for Batangas City last February 2013.

The reliable yet low-maintenance tsunami detection equipment is composed of a platform with a pole to which different sensors are attached: the ultrasonic tide sensor which notes the rise and fall of the sea level, dry sensor which determines whether water has receded immediately after a large earthquake thus indicating a very high possibility of tsunami occurrence, and wet sensors installed at heights of 1m, 5m, and 8 or 10m, which detect if tsunami water has already hit the pole. The sensors at the tsunami detection site communicate all signals to alerting sirens using GSM-communication developed by ASTI. Experts from both PHIVOLCS and ASTI designed the sensors and the whole system.

Previously, PHIVOLCS and ASTI had installed tsunami detection sensors in Bolinao, Pangasinan for the Lingayen Gulf with five pilot alerting sirens in Barangays Pugaro, Gueset, Binloc in Dagupan City, in the Poblacion of Lingayen, Pangasinan and in the Poblacion of Bolinao, Pangasinan; in Rapu Rapu for the Albay Gulf with five sirens installed in Barangays San Roque, Bonot, Puro, and Rawis in Legazpi City and in the Poblacion of Rapu Rapu; and in Corregidor and Lubang Island for both Batangas Bay and Manila Bay clusters. The Rapu Rapu Polymetallic Project, a mining company in Rapu Rapu island, is planning to donate similar alerting stations for their neighboring barangays in Rapu Rapu.

Under the TeWS project, each cluster will have one tsunami detection system as well as alerting stations or warning sirens for five pilot communities. In the case of Subic Bay, alerting sirens had already been put in place and are now operational in the Municipality of Subic, City of Olongapo and SBMA. The five pilot communities for each cluster shall be the model barangays for other neighboring coastal communities to have similar warning system, or alerting sirens at the least, coupled with their respective evacuation plans prepared by them.

“We have a grand plan for the tsunami monitoring system of the Philippines,” declared PHIVOLCS Director Renato U. Solidum Jr. “Under this project, we’re also testing a new type of low-power radio and we’re also putting tsunami tide gauges. This will enable us to have a more robust backup communication system via radio.”

“We will test these in five other areas. We had tested this in Corregidor but we will move it because we already have our own sensor there,” Dir. Solidum added.

Meanwhile, the group continues to train communities within the various TeWS cluster areas on understanding tsunami warning signals, and how to prepare for and implement evacuation, such as the two-day capacity building activity conducted by PHIVOLCS and ASTI for Mabacong and Sta. Rita Aplaya in Batangas City last February.

“In the next few years, we will also put up additional tsunami tide gauges in real time via satellite in various parts of the country,” the PHIVOLCS director said.

A few weeks ago, PHIVOLCS and the Japan International Cooperation Agency launched two comics materials and a video featuring Filipino residents in Japan who experienced the earthquake and tsunami which hit the country in March 2011.The materials will be distributed among schools in the country’s eastern shoreline in a bid to raise awareness on earthquakes and tsunamis and promote disaster preparedness.

The Department of Science and Technology-Philippine Council for Health Research and Development (DOST-PCHRD) recently named the Mariano Marcos State University (MMSU) and Visayas State University (VSU) as Tuklas Lunas (literally, cure discovery) Centers.


Tuklas Lunas Centers will serve as hubs of natural products research for drug development. Last year, DOST-PCHRD named the Mindanao State University-Iligan Institute of Technology (MSU-IIT) as its first Tuklas Lunas Center to serve the Mindanao area.


Apart from being centers for research, MMSU, VSU, and MSU-IIT will also facilitate collaborative research with other institutions in their respective areas.


As such, they will receive research and equipment grants from DOST-PCHRD.


“We are very happy that we have been chosen because it means our research efforts are being recognized. Of course, the equipment and research grant will greatly help in capacitating our faculty and students. We are also glad that our institution will have the opportunity to contribute for the country’s research effort in natural products research for drug discovery,” said Dr. Edgardo Tulin, vice president for planning and resource generation of VSU.


The criteria for choosing Tuklas Lunas Centers include excellent research and development track record, competitive staff, and institutional capacity. Tuklas Lunas Centers are part of DOST-PCHRD’s effort to accelerate drug discovery research in the country.

The Department of Science and Technology (DOST) has sealed an agreement with the country’s biggest cable provider alliance, the Philippine Cable Television Association, Inc. (PCTA), to create “DOSTv”, a 24/7 cable weather information channel to complement the services of DOST’s main weather agency, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

DOSTv shall broadcast accurate and up-to-date weather information of PAGASA, along with hourly satellite and Doppler images and weather sensors data from the Program NOAH website. NOAH, or the Nationwide Operational Assessment of Hazards, is DOST’s flagship program for disaster preparedness under the directive of President Benigno Aquino III.

The partnership between DOST and PCTA was formalized through the signing of a Memorandum of Agreement (MOA) recently during the PCTA 2013 Convention at the SMX Convention Center in Pasay City.

“This partnership significantly contributes to our ongoing efforts to mitigate the destructive effects of natural calamities such as typhoons and monsoon rains under the backdrop of climate change”, said DOST Secretary Mario G. Montejo.

DOSTv will be administered by the Department’s information arm, the Science and Technology Information Institute (DOST-STII) and is scheduled to debut this May 2013, to be carried by around 90 percent of PCTA’s cable franchisers. PCTA has more than 300 cable provider members all over the archipelago, according to PCTA Chairman Engr. Elpidio M. Paras.

Apart from DOSTv, PCTA members in the MOA also agree to host stations weather data gathering sensors, servers, and equipment to be provided by PAGASA, especially for its regional offices’ unreached areas and to improve the weather agency’s forecast capabilities.

“This is an important milestone for the cable industry as it is for the economy. Our lives are greatly affected by weather and climate, especially those in the regions whose primary source of income is agriculture”, PCTA Chairman Paras.

DOST-STII Director Raymund E. Liboro meanwhile stressed that “now is the time to look for means to increase the risk perception, mitigate the hazard, and prepare communities” as unprecedented meteorological events have recently struck the country.

Program NOAH Executive Director Dr. Mahar Lagmay presented during said convention a brief shocking footage of people being swept away to their deaths by even a knee-level flashflood.

“Had these people known the danger of an impending flashflood, they would have run in time for safety,” he said. “It is what we’re trying to avoid—the surprise—for it is what causes disasters and loss of lives. We simply cannot stress enough the importance of information.”

PCTA Chairman Paras also cited the importance of collaboration with weather and disaster experts, noting Cagayan de Oro’s recent linkage with PAGASA and Program NOAH. According to him, the linkage spurred by Cagayan de Oro’s devastating experience with typhoon Sendong enabled a two-hour warning before typhoon Pablo of last year hit the city, and resulted in zero casualties. An unprepared neighbor, Compostela Valley, unfortunately, was left with a many fatalities, he said.

This textile does not only make you look good. It also protects you from getting wet. More, it keeps you away from diseases caused by micro-organisms. A product of persistent research, this textile can truly be called smart.

“It has been a dream, until towards the end of 2012, when PTRI has finally developed a textile material that is comfortable, breathable but surprisingly water repellent and even anti-microbial,” revealed Dr. Carlos C. Tomboc, director of Philippine Textile Research Institute, an agency of the Department of Science and Technology.

The challenge to develop such technology came from DOST Secretary Mario Montejo who noted PTRI’s award-winning Christmas Belen made of taro leaves that were water-repellant. Since then, PTRI has been spinning possibilities into the broad range of functional and smart textiles.

This breakthrough research was carried out by a team of chemists of DOST-PTRI’s Chemical, Dyes, Auxiliaries and By-Product Utilization Section who came up with a finishing technology that makes fabrics water-repellant and anti-microbial.

Waterproof surfaces show the so-called “lotus effect,” referring to the lotus leaf’s ability to prevent water from drenching its surface. Tiny crystalline waxy bumps or protrusions and tiny hairs on the leaf’s surface trap the water droplet, stopping the water from reaching the lotus leaf’s actual surface.

To mimic this phenomenon, the team used several techniques, including chemical modifications via hydrophobic coatings and plasma treatments. After several attempts using various materials to make textile water repellent, the team was able to zero in on something that is just in the pocket: silver.

More particularly, the team discovered that silver nanoparticle and silver oxide nanocomposite can make cotton and pineapple fabrics water-repellent and even anti-microbial.

Silver is a known for its ability to kill various microorganisms, thus when used as repellant in textiles, it gives protection against microbe-caused diseases.

According to Jeannie Lynn J. Cabansag and Evangeline Flor P. Manalang, both registered chemists and the project leader and research staff, they used silver nanoparticles and submerged these in silicone oxide solution then applied to various textile materials.

The team found silver to be active against Klebsiella pneumoniae and Staphyllococcus aureus which cause pneumonia and skin infections respectively. The silver oxide thus was noted for its water-repellent property and, together with the silver nanoparticles, the combination resulted in a water-repellant, anti-microbial finishing for fabrics made of pineapple and cotton.

Conventional water repellent finishes literally form a coating on textile surfaces which compromises the breathability and comfort of cotton-based fabrics. Anti-microbial properties would be provided by yet another finishing.

However, in this technology, the finishing is applied on the fiber and yarns of the material and the anti-microbial properties of the silver nanoparticles are already dispersed in the silica network. With this, comfort and form are not necessarily traded-off over function.

This development is part of the string of PTRI-developed technologies that integrates nanotechnology to textile finishing, now coined as “nanofinishing.” This new technology produces smart, bio-functional, and truly Philippine-made textiles.

Water particles are unable to seep through the textile. This is called the lotus-effect.
