5.2 Oil Spill in the Philippines in March 2023
PhilSA requested emergency observation on oil spill, and held media briefing/press
conference with estimated extent of oil spill maps provided by Sentinel Asia
✓ In response to this incident, the Japan Disaster Relief (JDR) Expert Team wasdispatched for gathering information on the oil spill situation, checking oil removal
and control activities and technical advisory✓ JDR Expert Team used estimated extent of oil spill maps provided by Sentinel Asia
✓ 4 organizations provided satellite data and 2 organizations provided estimated extent
of oil spill maps

6. 8th Joint Project Team Meeting• September 17-18, 2023
• 85 participants from 35 organizations✓ Presentations from new Sentinel Asia members, Users, Data Analysis Nodes✓ Indonesia Session: Accelerating satellite-based data and information for disasterrisk management in Indonesia✓ Discussion session to further promote the STEP-3 Strategic Plan of Sentinel Asia
✓ Training workshops for Capacity Building12

6.1 Indonesia Session
Special Session “Accelerating Satellite-based Data and Information for
Disaster Risk Management in Indonesia”
・ Dr. Udrekh and Mr. Putra of National Disaster Management Authority (BNPB) introduced theapplication of satellite data for Indonesian Disaster Risk Reduction.
・ Dr. Hadi of Diponegoro University shared experiences of providing Value Added Products(VAP) to BNPB and advised the importance of communication and collaboration with BRIN,
BNPB and Universities to accelerate creation of supportive VAPs.
・Dr. Jamal of Center for Geological Survey, Ministry of Energy andMineral Resources (ESDM) emphasized the importance of Satellite
Data be used to accelerate updating Geological Mapping to 127 active
volcanoes which only 69 is currently covered by conventional methods.
©ESDM・ Dr. Yenni of BRIN expressed the importance of high temporal/spatial/spectral resolution
images for regular monitoring of volcanoes with the example of Mt. Semeru erupted
repeatedly in recent years.

136.2 Systems for Disaster Risk Reduction
Several organizations shared their Web-Geographic Information
Systems (Web-GIS) to share satellite images, value added
products, and disaster related information.

Disaster Management and Decision Support System (AYDES) and AFAD-RED system. ©AFAD• AFAD developed “RED system”, integrated in AYDES, that provide
almost real-time estimation of seismic intensity map of an earthquakeand damage assessment map.

6.2 Systems for Disaster Risk Reduction• For UNWFP, damage assessment, affected
population estimate, road clearance information,etc. are crucial for delivering the relief food supply
within 72 hours after occurrence of disaster.
• Advanced Disaster Analysis and Mapping(ADAM) provide The Shake Intensity Map,Epicenter Map, Population Impact Table forearthquakes provided shortly after the event• For Flood, Population and Cropland Impact Map
and Flood Map/ Forecast are provided©UNWFP• For Pacific Islands, lack of data sharing infrastructure ischallenging issue.
• Pacific Community (SPC) developed Digital Earth Pacificwhich will allow the Pacific Community’s 27 member
states to share the disaster related information.
• The application may be also used for climate change andfood security purposes©SPC15

6.3 Applications of Sentinel Asia by End Users
Participants shared their applications utilizing Sentinel Asia’s data in various phasesof disaster risk reduction cycle such as mitigation, preparedness, response andrecovery.

6.7 Expectations to Sentinel Asia
Participants shared Expectations to Sentinel Asia.
【For Satellite Data】• AFAD showed the necessity for More High Resolution OpticalImages. In the case of Turkey Earthquake in Feb. 2023, they
provided valuable information for damage mapping. (exbuilding destruction).
• BRIN emphasized the importance of hightemporal/spatial/spectral resolution images forregular monitoring of volcanoes

response in cases of earthquake and tsunami for
immediate evacuation【End User Recognition】©BRIN• Central Asian Institute for Applied Geosciences (CAIAG) and Space and Upper
Atmosphere Research Commission (SPARCO) shared their experience ofinteractions with the DMO that, more recognition towards benefits andpotential of Space Applications to DRR is crucial for Capacity Building and20
Collaborative Disaster Risk Reduction Network.

7. Way Forward✓ Steering Committee meeting is planned for both online-meeting andFace to Face meeting.

12 Steering Committee Members of Sentinel Asia

✓ Face to Face Meeting with Disaster Management Organizations ofvarious countries are planned to collect cases of successful
applications of Sentinel Asia and Validation of Ground Truth data,
Local information of Field Survey for validation of Data Analysis✓ 9th JPTM of 2024 is planned and it is to be determined21

8. Summary✓ Sentinel Asia is an initiative aiming space-based international
cooperation for disaster management in the Asia-Pacific region✓ Sentinel Asia has responded over 420 emergency observation request
since 2007
✓ Sentinel Asia is expected to implement not only emergency observation
but activities covering entire disaster risk reduction cycle including
mitigation/preparedness and recovery phase after a disaster✓ In the 8th JPTM of 2023, Sentinel Asia members shared theirapplications that covers all cycles of disaster risk reduction.
✓ Participants of JPTM have discussed the importance of higher
recognition among the Disaster Management Organization and their
feedback after using Sentinel Asia’s data.
