Measuring ground deformation by observation twice.
・Ground deformation in Sakurajima
15 Aug 2015 Volcanic Alert Levels 3→4
16 Aug 2015 ALOS2 Emergency Observation
・By observation always, you can catch volcano erupted sign.
・ALOS/PALSAR2: The observable range is expanded.(Observation on both side)
【Point】
・Discrimination damage area of Tsunami or a flood.
【Point】
・Discrimination damage area of Tsunami or a flood.
【Explanation and Other Information】
・A Flood area, which is caused by Tsunami, a heavy rain, cover a wide range.
・It’s difficult to discriminate the whole of damaged area.
・By using Optical sensor, you can discriminate damaged area intuitively.
・By using SAR, you can observe when weather is bad condition like cloudy.
(These images were observed by ALOS when the Great East Japan Earthquake was occurred.)
【Point】
・Discrimination landslide area.
【Point】
・Discrimination landslide area.
【Explanation and Other Information】
・Because landslide tend to occur in mountainous region, it’s difficult to enter the area.
・By using Optical sensor, you can discriminate area of landslide.
(These images were observed by Terra/ASTER when the Pakistan earthquake, 2005. Analyzed by AIST.)
・Three-line sensor data Is more useful.
・By using SAR, you can monitor landslide sign.
(The image was observed by ALOS, Gassan Mt. Japan. Analyzed by GSI.）
【Point】
・Communication by utilizing satellite between headquarters and stricken area.
【Point】
・Communication by utilizing satellite between headquarters and stricken area.
【Explanation and Other Information】
・Disruption ground communication network by disaster.
→You can not contact with a stricken area.
・Communication satellite has robustness to ground disaster.
→You can contact with a stricken area.
・You have to prepare only small, portable ground antenna.
・You can use a mobile data terminal.
・Have a high affinity with general equipment. (because of IP interface)
【Point】
・WINDS and ETS-Ⅷ were used when the Great East Japan Earthquake was occurred.
【Explanation and Other Information】
・At the Great East Japan Earthquake, Mar 2011
East Japan was damaged hardly, so many local-government lost a means of communication.
・By utilizing WINDS and ETS-Ⅷ, we could contact with a stricken area.
・For TV conference system, internet access for citizens for checking safety information.
【Point】
・Introduce Integrated Flood Analysis System “IFAS” using free available satellite rainfall data and topography data.
【Explanation and Other Information】
・IFAS has a spill modeling, runoff analysis, the analysis results of the graphic display function.
・Satellite rainfall data and altitude, land-use data needed as input data of IFRS are free available.
・Predict the flood, forecasting/warning suitable timing/areas, that’s the help prevent the damage.
【Point】
・Introducing the J-ALERT which is a disaster management system using communication satellite.
【Explanation and Other Information】
・The J-ALERT is an quick alert system to alert for citizens when emergency that not having enough time.
・A Satellite is used to communicate from Fire and Disaster Management Agency to local-government.
【Point】
・Information category of J-ALERT
【Explanation and Other Information】
・Information distributed by J-ALERT is various.
・Emergency warnings.(A ballistic missile, Earthquake early warnings, Tsunami warnings, etc)
→ Distribute warnings automatically.
・Other cases(Meteorological warnings, Advisories, Prediction)
→ Settings by local-government.
・Since 2012, FDMA and local-government train operating J-ALERT together.
【Point】
・Overview of Sentinel Asia
【Explanation and Other Information】
・A cooperation scheme between space agencies and disaster management agencies of Asia and Pacific.
・Started from proposal by JAXA, 2005.
・When disaster occur, Satellites owned by members observe emergently.
・Observation images are shared on internet system. (JAXA developed system.)
・HRD about utilizing observation data.
【Point】
・Overview of International Charter on Space and Major Disaster
【Explanation and Other Information】
・An international cooperation of space agency.
・When disaster occur, Satellites owned by members observe emergently.
・Started from proposal by CNES, 1999.
・15 space agencies are participating.
【Point】
・Overview of International Charter on Space and Major Disaster
【Explanation and Other Information】
Example：Flood in Thailand
・Flood damage caused by the rain which lasted from July 2011. Flooding lasted for several months.
・10/77 provinces include capital Bangkok suffered from flood. More than 800 people were killed. Foreign capital factories include Japanese capital one became shutdown.
・Thailand had asked for emergency observation through International Charter and Sentinel Asia. Then satellite images were offer from many countries.
・For grasp whole flood area of 6 million ha, satellite image is more suitable than aerial photograph because satellite image’s observation width is wider than aerial photograph’s one.
・Furthermore, periodicity of orbiting satellite allows continuous monitoring of several months.
・By utilize earth observation data, you can grasp disaster damage more efficiently.(e.g. Earthquake, Volcano, Tsunami, Flood)
・Even if human and airplane can’t enter damaged area due to a danger(e.g. Landslide, Radioactivity), earth observation satellite can observe from space.
・By hazard map made from earth observation data, you can take refuge efficiently and decrease damage of disaster.
・By utilize Communication satellite, you can contact with damage area even if ground NW is disrupted.
・We can provide you disaster prevention solution with space technology, because of Japan has suffered from many disasters.
