RADI Provides Satellite Data Support for Latest Iran-Iraq Earthquake Rescue
 Date: 2017-11-29  Page Views:

Hours after a 7.3 magnitude earthquake struck the border region of Iran and Iraq at night of November 12, 2017, the Institute of Remote Sensing and Digital Earth (RADI), Chinese Academy of Sciences (CAS) launched its disaster emergency response program at 02:27 Beijing time, on November 13, aiming to providing timely spatial data support for disaster mitigation.

RADI scientists immediately started to collect and process pre-quake historic data as well as acquire latest post-quake satellite data. The work got quick support from China’s satellite operational agencies. Chinese high resolution satellites have made special observing plan to get post-disaster damage images as soon as possible.

Pre-quake data for the Iraq region was released at noon on November 14, which is accessible from (Username: radi_ Iraq, password: radi_ Iraq). The image is taken by China’s high-resolution satellite GF-2 on August 11, 2017.   

The latest satellite image spots blocked roads due to landslides surrounding the Darbandyhan dam in Iraq.

A remote sensing monitoring map is produced to analyze the building damage in Sarypolza Zabu of Iran, one of the worst affected areas. The map comprises of a post-quake image taken from BJ-2 and a pre-quake image taken by GF-2 satellite on January 16, 2017. The comparison analysis reveals significant damage to the buildings in the area.

 Remote Sensing Monitoring map shows building damage in the Zarpole Zhabur area of Iran.

Post-quake SAR image from GF- 3 shows damages in Darbandhan dam and surrounding town.

RADI’s disaster emergency response program has been successfully launched for huge natural disaster events both in China and across the world by sharing essential and timely data for disaster response and research.

It has played an important role for the disaster reduction, such as Wenchuan earthquake in 2008, Yushu earthquake in 2010, Australian bushfire monitoring in 2013, and Mexico earthquake in September of 2017.

The satellite data for the program is majorly acquired through a big science facility housed by RADI, the China Remote Sensing Satellite Ground Station (RSGS). Since its operation in 1986, RSGS has received, processed and archived more than 30 satellites, with some four million scenes of satellite data, boasting China’s biggest Earth observation historical database. RSGS has the capacity to receive real-time satellite data that cover the entire Chinese territory and 70% the land area of Asia.  

This program has got support from and become part of data sharing programs initiated by such international organizations and programs as GEO, AOGEOSS, CODATA, DBAR, WDS, IRDR, APSCO, OpenStreetMap and UNOSAT.
