China has mobilized at least eight of its satellites to help with search-and-rescue and damage control work after last week’s massive blasts in Tianjin.

The China Aerospace Science and Technology Corp activated its emergency response mechanism on the morning of Aug 13, several hours after the deadly warehouse explosions rocked the port city.

It used the Gaofen 2 high-resolution Earth observation satellite, the Ziyuan 3 Earth mapping satellite and Shijian 9A technology test satellite to perform four observation operations between Aug 14 and Aug 17 this week, according to a statement on the company’s website.

The response mechanism was activated by the company’s China Center for Resources Satellite Data and Application.

The center also used the Huanjing 1A low-resolution Earth observation satellite, the CBERS 4 remote sensing satellite and the Gaofen 1 high-resolution Earth observation satellite to acquire data from the scene of the blasts.

Images and data from the satellites have been sent to government departments, including the Ministry of Environmental Protection and the State Oceanic Administration, to help with damage assessment and rescue work, the statement said.

The National Satellite Meteorological Center also deployed weather satellites developed by the Shanghai Academy of Space Flight Technology.

These included the Fengyun 2G and Fengyun 3B satellites to detect fires in the blast zone, the statement said.
