Geological disaster is one kind of the major natural disasters which menaces and can make heavy losses for the economical construction and mankind living environment, and has been taken seriously in recent years by all the countries in the world. The investigation, monitoring and prediction of geological disasters by using various advanced technology including remote sensing has become a common task for mankind. In this paper the research results in recent years for geological disasters using remote sensing technology in China were recounted with a lot of examples. The strategy and main tasks were proposed about how to bring the advantage of remote sensing into play further and to reduce the losses of geological disasters in the "Decade of Natural Disaster Reduction"(DNDR) under the United Nations resolution.
