Speleothems are of not only value for tourism development, but also rich information in paleo-climate and paleo-environment, and also a recorder for earthquake information providing good material for earthquake vestiges study. In the recent ten years, some special speleothem collapse has been discovered in cave. Some fracture, speleothem collapse in cave occured or were produced after the earthquake of magnitude 8.0 in Wenchuan County, Sichuan, China, at 14:28, on May 12th, 2008, suggesting the collapse is closely related with earthquake activities. This paper recover the prehistoric earthquake events that not recorded in historic data, and compare the time and intensity of the earthquake events, according to the vestiges recorded in the speleothem collapsed materials by new and old earthquake and the U-series dating age etc. The vestiges recorded in the speleothem collapsed materials in cave can provide relevant evidence and proof for studying the earthquake history, supply the lost historic records of earthquakes, and provide a new perspective for earthquake monitoring and forecasting in the future.
