On July 5th, a breach occurred in the dike along the Tuanzhouyuan of Dongting Lake, with the breach expanding to 226 meters. This caused flooding of an area covering 47.64 square kilometers, necessitating the emergency relocation of 7,680 residents. All parties involved in the rescue and emergency response adopted measures of `resting personnel while keeping machines running and working in shifts` to continuously advance the work of sealing the breach around the clock.
Following the disaster, Lu Hai Kong Jian immediately arranged for the Dong Fang Hui Yan 01 satellite to observe the affected area based on satellite transit conditions. Up to now, imaging has been completed twice on July 7 and July 8, and provided to relevant units in a timely manner to promptly grasp the information on the situation of the disaster.
