1 Contribution of Sentinel Asia Activities to Disaster Management in Asia Pacific Region: Sentinel Asia Success Story in the Philippines Project Arturo Daag PHIVOLCS, PHILIPPINES 13 October 2015 Bangkok Thailand

2 Framework of Sentinel Asia Success Story in the Philippines: Step 1: 2009 Team Japan Team Philippines Focal Point of Activity in Philippines Advisory Agencies Agreement PCIEERD, DOST NDCC Contract JAXA PHIVOLCS Advice Implementing Agencies (L. Support) NAMRIA PAGASA MGB NDCC Disaster Information Dissemination End User Agencies (T. Support) The local government, Rescue Authority and Press etc

3 Success Story in the Philippines (1 st Phase 2009) Capacity Building on Remote Sensing Hazard maps (Flood, Lahar and Landslide) of 3 study areas (Antique, Iloilo and Mt. Mayon) were created by using ALOS Pansharpen Image and DSM. Lahar - Mt. Mayon (PHIVOLCS) Flood - Iloilo City (PAGASA) Landslide - Antique (MGB)

4 2009 Sentinel Asia Success Story in the Philippines Project Introduction 20 March 2013 Makati City Local Participants: 43 PAGASA, MGB, NAMRIA, OCD, PHIVOLCS, UP, APSEMO, LGU

5 Change Detection Using Pre and Post Disaster Images (Case Study: Botolan, Zambales) Flooded areas Overflow point; dike breached January 27, 2009 August 11, 2009

6 Modeling of Lahars in Mayon Volcano using LAHARZ

7 Updated Mayon Volcano Lahar Hazard Map through Numerical Modelling using ALOS PRISM

8 Success Story in the Philippines (2nd Phase, ) Application of GSMap and InSar Application of GSMaP for Landslide Warning, and Interferometry for monitoring of Land Subsidence and Earthquake/Volcanic Eruption have been studied. Volcano & Earthquake Monitoring - Mt. Mayon, Mt. Taal & Valley Fault Landslide Warning - Albay Land Subsidence - near Manila

9 Capacity Building on use of GSMap and InSAR ADVANCED TRAINING -Interferometry -GSMAP, RBFN, SWI

10 How Can We Evaluate the Risk using the CL? The risk is high. Hourly rainfall (mm/h) Critical Line (CL) Snake Line Soil Moisture Index (mm) Hourly Rainfall Total Rainfall Time

11 August 14, 2012 Established Landslide Warning server at NTT Data Tokyo Office Website

12 May 7, 2011 Landslide Mesh in Albay (GSMaP and AWS) Feb 12, 2012 Landslide CL July 25-27, 2011 Mt.Malinao 0.5 July 25-27, 2011 Mt.Masaraga Dec 29, 2010 Landslide Jul 25-27, 2011 TS with Monsoon Jan, 2011 Landslide

13 September 7-9, 2011: Advanced Training on Landslide Modelling and Warning Using Satellite-based Rainfall Data and Soil Water Index PARTICIPANTS 28 APSEMO(2), BSWM(3), DPWH(1), MMDA(2), MGB(4), NAMRIA(1), OCD(2), PAGASA(4), UPDGE(1), PHIVOLCS(10)

14 GROUND SUBSIDENCE MAPPING AND MONITORING USING ALOS PALSAR Mar.2011 Feb.2007 (1472 Days) A B C D E Average of 4cm yearly subsidence 14

15 Success Story in the Philippines (3rd Phase, ) Application of GSMap and PSInSar Addition more monitoring points for Landslides and Flood Alert System using GSMap PSInSar Analysis of Ground Subsidence and Volcano Deformation 15

16 Phase 3: Overview of the prototype-system The Landslide and Flood disaster Early Warning System with GSMaP Input GSMaP AWS GSMaP Correction Corrected GSMaP Tank model Soil Moisture Index Run-off 10km First user list is necessary (User s Name and address) Login: User ID Password Landslide warning system by Non-leaner Critical Line Flood warning system by estimating water level Web Browser Alert of landslide disaster Output Alert of flood disaster

17 Web-based Warning Interface Rainfall map Warning map (Landslide and flood) 2 Map (rainfall and warning) Time-rainfall graph and CL

18 Time-series Interferometry at Manila PSInSAR, Stacking and GPS Stacking with 23 scenes

19 -PSInSAR -Mayon image processed ( data set) PSInSAR vs. DInSAR -DInSAR data set

20 Success Story in the Philippines (4th Phase, ) Application of GSMap and InSar Enhancement and calibration of GSMap in specific sites. From prototype to operationalization. Deformation analysis of the Valley fault System that is capable of generating 7.2 magnitude that is transecting Metro Manila. Analysis using ALOS 2

21 Other Activities Emergency Observation Requests Project manager in Sentinel Asia UN Charter

27 Recent Emergency Observations Request: Sentinel Asia Dec 16-17, 2011 TY Sendong Barangay Macandasig, a point bar deposit, was developed for housing. Postdisaster image from THEOS showing the completely devastated point bar area. Ground photos of Barangay Macandasig, Cagayan de Oro City. Flashflood completely swept the village and flood water depth is more than 3 meters.
