Authorities said more than 300 people have now perished in the continued floods in China. The figure is more than three times the previously announced death toll.

The Henan provincial government said during a news conference in Zhengzhou Monday that 302 people have been confirmed dead and more than 50 are still missing. Officials said that most of the victims were from Zhengzhou. 292 out of the 302 people killed were from the provincial capital.

Last week, officials announced that at least 99 people had been killed by the continued floods. Record rainfall has drenched major cities in Central China since last month. The continuous rain, worsened by the arrival of typhoon In-Fa last week, caused rivers to overflow across China's eastern and central provinces.

Last month, 14 people died inside train cars trapped under a subway in Zhengzhou. Floodwaters breached a wall near a subway system, submerging the entire underground tunnel with water. Several dozen people were rescued but workers were too late to save those trapped deeper inside the tunnel. 

Video of the incident became viral online. Passengers on Line 5 of the city's subway were able to capture video of the water quickly rising inside their train cars.

Authorities said 189 people were killed by floods and mudslides, 54 were crushed when their houses collapsed, and 39 died after being trapped in underground areas such as basements and garages.

Apart from the human casualties, the floods also resulted in billions of dollars in economic damages. The heavy rain, which sometimes hit 8 inches per hour in some areas, had destroyed acres of farmlands, homes, and public infrastructure. Economic activity also came to a halt as roads and railways were rendered impassable by the heavy downpour.

Officials estimate that about 625,000 acres of crops had been destroyed by the floods. The total damage caused by the rains is now estimated to be around $14 billion. Since last month, more than 1.5 million had to be evacuated from their homes due to the floods.

The Chinese government recently established a committee to investigate the incidents. The team will investigate the affected cities' disaster response and flood control systems. The central government said anyone - including city officials - found guilty of dereliction of duty will be held accountable.
