earthquake, active fault, geohazards related to geophysical fields,
eco-geological hazards, landslides, land cracking, surface-swapping flood, tube

artificial earthquake. Some of them are divided more detailedly, such as:
geohazards related to geophysic fields with 3 types and to karst with 4 types.
