Progress Report: Sentinel Asia Success Story in the Philippines 3 rd Joint Project Team Meeting on the Sentinel Asia STEP-2 July 6-8, 2010 Hyatt Hotel, Manila, Philippines Renato U. Solidum Jr. Director Philippine Institute of Volcanology and Seismology Department of Science and Technology
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
Prone to many natural hazards and have been affected by past disasters Sentinel Asia recognizes that the Philippines has sufficient experience and mechanism in disaster management Philippines has signified interest to promote utilization of Sentinel Asia Why in the Philippines?
Implementation scenario General To make end users in the Philippines learn about the Sentinel Asia Initiative and its usefulness. 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. 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. Duration: early 2009 2010 Sentinel Asia Success Story in the Philippines

Creating Hazard Maps with the use of ALOS Satellite Data Sentinel Asia Success Story in the Philippines Flood - Antique Province (MGB) Lahar Mayon Volcano (PHIVOLCS) Flood - Iloilo City (PAGASA)
Study area 1: Mayon Volcano (PHIVOLCS) 2462m high; most active volcano in the Philippines; 49 historical eruptions frequent occurrences of lahars ~100,000 people live along slopes 466mm rainfall in 12 hours 30November 2006 caused lahars; deposited 31 million m 3 of debris, 1-4 m thick in 12 km 2 area; caused death of close to 1,000
Digital Elevation Model ALOS PRISM smooth SRTM detailed PRISM Modeling of Lahars by LAHARZ software USGS Open Source Software
Fieldwork at Mayon (Feb 2010) FIELD VALIDATION: to collect Ground Control Points for DEM Validation Insrument used: Trimble 5700 GPS

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 Participants JAXA, PHIVOLCS, PAGASA, MGB, NAMRIA, OCD, PCASTRD and local disaster managers 1 st Workshop Introduction of Project; 20 March 2009, Makati City; 2 nd Workshop Sharing of preliminary results and information; Ilo-ilo City 3 rd Workshop Presentation of results, SA systems operation, open source tools for image overlaying to local maps; Manila City
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 to the local government 10 Flooded villages: 1.5 m high
