The Use of Sentinel Asia in the Philippines 16th Session of the Asia Pacific Regional Space Agency Forum 28 January 2010, Bangkok, Thailand

Renato U. Solidum Jr.

Director Philippine Institute of Volcanology and Seismology Department of Science and Technology

Background on natural hazards in the Philippines

Tropical Cyclones • ~ 20 cyclones/year enter Philippine Area of Responsibility ; ~ 9 cross the country/year • cyclones brought disasters due to strong winds, storm surges, floods, and landslides • other weather systems bring heavy rains causing floods, landslides

Volcanoes in the Philippines

(~300 volcanoes, 23 active volcanoes)

Pinatubo 1991

Mayon 2009

Earthquake Activity in the Philippines

(20 earthquakes recorded per day; ~ 200/ year; ~ 90 destructive earthquakes and ~ 40 tsunamis for past 400 years)

M7.8 Luzon Earthquake

>M4.0 Earthquakes

Use of Sentinel Asia in the Philippines

Sentinel Asia Success Story in the Philippines Objectives (1)

Establish a pioneering example using Sentinel Asia initiative as a Success Story in the region

(2)

Effectively apply information delivered by Sentinel Asia for emergency response

(3)

Share the pioneering example to other members

(4)

Demonstrate usefulness of Sentinel Asia in the region

Implementation scenario Sentinel Asia Success Story in the Philippines

> In general

To make end users in the Philippines learn about the Sentinel Asia Initiative and its usefulness.

> In the preparation phase

Philippine participants prepare for potential disasters by making hazard maps for landslides, floods and lahars using ALOS data, in cooperation with Japan, so that communities in the Philippines can increase its awareness and preparedness for potential disasters.

> In the emergency phase

Philippine participants ask Sentinel Asia Initiative for Emergency Observation Request (EOR) so that they may properly identify/detect and assess the affected areas when a disaster strikes for effective disaster response. This will also validate the usefulness of ALOS imagery.

Lahar – Mayon Volcano (PHIVOLCS)

Study area 1: Mayon Volcano (PHIVOLCS) •2462m high; most active volcano in the Philippines; 49 historical eruptions • frequent occurrences of lahars; 466mm rainfall in 12 hours November 2006 deposited 31 million m3 of debris, 1-4 m thick in 12 km2 area; caused death of close to 1,000 • ~100,000 people live along slopes

Technical Training Sentinel Asia Success Story in the Philippines

• February 2009 - 1-2 day technical training per agency: PHIVOLCS, PAGASA and MGB •24-28 August 2009 - technical training for OCD, NAMRIA, MGB, PAGASA, PHIVOLCS

Workshops Sentinel Asia Success Story in the Philippines

•20 March 2009 – introduction; Makati City; 43 local participants: PHIVOLCS, PAGASA, MGB, NAMRIA, OCD and local disaster managers •15 December 2009 - sharing workshop, Iloilo City; PHIVOLCS, PAGASA, MGB, NAMRIA, OCD, Iloilo City, Iloilo Province and Antique Province • next activity: March 2010

Emergency Observation When disaster happens, Sentinel Asia can accept Emergency Observation Request from users, and Space Agency observes disaster afflicted area by Satellite. Then satellite imagery are provided to users.

EOR: Flooding related to SW monsoon rains in Botolan, Zambales, Luzon Island, August 8, 2009 Objectives: 1. Determine extent and cause of flooding in A Botolan; threatened by lahars and floods after 1991 eruption of Pinatubo 2. Determine changes in the river system 3. Recommend actions by the local government
