| Abstract: | Guangxi is a large province of karst in southwestern China.The karst areas are up to 42 percent of the total areas of Guangxi.Karst caves develop very well with at least 60 000 caves.Landscape resources in caves are very rich,which are a mass of wealth for traveling in Guangxi.The sediments in the cave are not only the valuable for tourism development,but also contains rich information of pale climate,pale environment and the earthquake.Thus,it is a good material to study earthquakes in history.The earthquake activity not only lead to the geologic hazard or phenomenon of fracture and collapse of caves and speleothem,but also lead to change or enlarge of the waterway of percolation water in epikarst zone.This can impels supplementation of cave dripping water to increase and excite the growth of stalagmites or deposit of speleothem.This paper will recover the earthquake information according to the new and old earthquake historical remains of cave and speleothem.We hope that our studies can help people to study new active fractures or faults and reconstructing the earthquake history,and can provide a new perspective to the future earthquake monitoring and forecasting. |
