China has mobilized several remote sensing satellites to aid rescue and relief efforts following a dike breach on Friday at Dongting Lake, the country's second-largest freshwater lake in central Hunan Province.

According to the China Centre For Resources Satellite Data and Application (CRESDA), Gaofen-3 02, Gaofen-3 03, Gaofen-1, and Gaofen-4 satellites have been deployed to provide real-time monitoring of the affected areas.

As of Saturday, satellite imaging has been conducted five times, CRESDA said, adding that data has been swiftly provided to the relevant departments.

On Friday afternoon, a Dongting Lake dike burst in Tuanzhou Township, Huarong County under Hunan's Yueyang City, triggering flooding in the area.

"We will continue to closely observe the disaster situation in Huarong County and provide remote sensing satellite data and analysis services for flood rescue and relief, disaster assessment and other work," CRESDA said.
