After Ruihai company dangerous goods warehouse fire and explosion accidents occurred on 12 August 2015 China Centre for Resources Satellite Data and Application (CRESDA) owned by China Aerospace Science and Technology Corporation (CASC) launched an emergency response mechanism at 8:00 on August 13. From 14 to 17 August, the center arranged GF-2, ZY-3 and SJ-9A satellites to carry out 4 emergent observations, and obtained important data. Meanwhile, the HJ-1A medium- and low-resolution satellite, ZY-1 04 satellite and GF-1 satellite also obtained satellite data on the explosion area from 12 to 15 August.
Up to now, the center totally obtained and shared nine satellite images on the explosion accident area and provided to the Ministry of Environmental Protection, State Oceanic Administration and other ministries for disaster assessment and relief command.
Since August 3, CASC has launched the emergency response mechanism 4 times, closely monitoring the Myanmar floods, "Soudelor" Typhoon, Tianjin Port fire and explosion and Sanyo landslides in Shaanxi Province. Especially from 13 to 15 August, 4 incidents require parallel monitoring. This caused great challenge to the satellite emergency observation capability and the Center’s emergency operation and service capability.
Under the careful command and planning, the Center successfully completed the task.
