China is using satellite imaging technologies to analyze the January 23 earthquake that hit Xinjiang Uygur Autonomous Region.
Less than an hour after the first jolt, the China Earthquake Administration asked the China National Space Administration (CNSA) to help image the quake-hit areas. The CNSA then coordinated the resources from government institutions, state enterprises and private companies to control civil and commercial satellites, including Gaofen-1, Gaofen-4, Huanjing-2 and Peicheng-1.
Historical images were also loaded to help analyze the situation. All the image data was transferred to researchers through a national data-sharing platform for remote sensing. The first batch of data was successfully transferred at 3:30 p.m.
More satellites are planned to be included in the emergency response, according to the State Administration of Science, Technology and Industry for National Defense (SASTIND).
The Gaofen satellite series is part of China's all-weather, 24-hour global Earth remote sensing system. The launch of the Gaofen-1 began back in April 2013, while the Gaofen-4 was launched in late 2015.
In addition to disaster prevention and reduction, the Gaofen satellites can also be used in land surveys, urban planning, road network design and crop yield estimates.
