The most notable events included floods, heavy winds, hail and a range of geological disasters, said Yang Xiaodong, deputy head of the disaster relief department of the China's Ministry of Civil Affairs.
In total, natural disasters caused 298 billion yuan (USD 44 billion) in direct economic losses. About 400,000 houses collapsed and 6.24 million residents were relocated, with the vast majority of disasters occurring since June.
Total damage in the first seven months of the year was much heavier than over the same period in recent years, Yang said.
Disasters since June have caused an estimated 253 billion yuan in direct economic losses. Anhui, Fujian, Guizhou, Hebei, Hubei, Jiangsu and Jiangxi were the hardest hit regions.

Local governments in Hebei underestimated the intensity of the rain, failed to provide sufficient emergency response, and were late and inaccurate in disaster assessment, Yang said in response to the devastating flash floods that left 130 people dead and 110 others missing in Hebei last week.
"Torrential rain cut off local communication, power and traffic, resulting in delayed warnings about the impending deluge, failure to evacuate people in danger and failure to report casualties in time," said Yang, who has just returned from Hebei.
Hebei has not seen such severe flooding for 20 years, which led to lack of awareness and experience to deal with the disaster, Yang noted, adding illicit occupation of river courses had prevented flood passage and control.
Further investigation is under way, and officials who failed to perform their duties will be harshly punished, Yang added.
This year, the ministry and the China National Commission for Disaster Reduction have sent 17 emergency teams to assist relief work on the ground, the report said.
