Establishment of Sentinel Asia Success Story in the Philippines OUTLINE 1. Introduction 2. Project Concept 3. Project Implementation 4. Accomplishments 5. Future Plans
Success Story 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 JPT members 4. Demonstration of Usefulness of Sentinel Asia in the region
Why in the Philippines? The Asian region has been seriously damaged by natural disasters and economic losses are increasing year by year due to increasing vulnerabilities. Most Asian countries participating in Sentinel Asia face this situation. Sentinel Asia recognizes that the Philippines has sufficient experience and mechanism in disaster management. The Philippines, in discussions with JAXA, has signified interest in promoting the utilization of Sentinel Asia in the Philippines.
PHILIPPINE RISK PROFILE Located along the typhoon belt on the North Pacific Basin where 75 percent of typhoons originate An average of 20 to 30 typhoons occur each year, and 5 to 7 of which can be destructive Situated at the northwestern fringes of the Pacific Ring of Fire, where two major tectonic plates of the world (i.e. Pacific Plate and Eurasian Plate), meet This explains the occurrence of: - 20 earthquakes recorded per day - tsunamis - 90 destructive earthquakes for the past 400 years - existence of around 358 inactive, 27 potentially active and 22 active of which 5 are classified as most active
Implementation Scenario 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, mudslides and floods 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 asks 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

Future Work A more detailed image classification and ground-truth to monitor changes in morphology and landuse using images from JAXA. Collect survey-grade GPS locations (x,y,z) to augment data on DEM generated using ALOS-PRISM Updating of Volcanic Hazard Maps, especially on LAHARS, based on newly acquired images and DEM.
