According to the degree of hazard and scale, there are four levels of geological disaster danger and geological disaster disaster: very large, large, medium and small.
Very large geological disaster danger: geological disaster danger threatened by disaster, requiring relocation and transfer of more than 1,000 people or potentially causing economic losses of 100 million yuan or more. Very large geological disaster hazard: a geological disaster with more than 30 deaths or direct economic losses of more than 10 million yuan caused by the disaster.
Large-scale geological disaster risk: a geological disaster threatened by a disaster that requires the relocation of more than 500 people or less than 1,000 people, or a geological disaster risk with a potential economic loss of more than 50 million yuan or less than 100 million yuan. Large geological disaster hazard: geological disaster hazard with more than 10 or less than 30 deaths or direct economic losses of more than 5 million or less than 10 million yuan due to the disaster.
Medium geological disaster danger: a geological disaster threatened by disaster, requiring relocation and transfer of more than 100 people or less than 500 people, or potential economic loss of more than 5 million yuan or less than 50 million yuan. Medium geological disaster disaster: a geological disaster disaster with more than 3 or less than 10 deaths or direct economic loss of more than 1 million or less than 5 million yuan due to the disaster.
Small geological hazards: geological hazards threatened by disasters that require relocation and transfer of less than 100 people or potential economic loss of less than 5 million yuan. Small geological disasters: geological disasters with less than 3 deaths or direct economic losses of less than 1 million yuan due to the disaster.
