The impend forecasting of strong earthquake is still an unsolvable scientific qu estion in the world. Based on our analysis of the disadvantages of present earth quake forecasting, this article discussed the probability of spatial detect tech nique that is used in earthquake's forecasting, and then summarized the status, extent and some unanswered questions of those new techniques and methods in dome stic and international applications. In earth's crust, where there is the broken proceeding, there is the changing the media of the energy between inside and ou tside. The phenomena can be caused by crust stress changing under ground, temper ature up on earth surface and low frequency electromagnetic emission in atmosphe re by interface match of various solid earth and atmosphere circle. Furthermore, it is possible to acquire strong earthquake information from space remote sensi ng data. In so far, three sorts of strong earthquake's information can be detect ed using various sensors of satellites. There is crust deforming in geologic bod y, thermal abnormal on surface and electromagnetic over atmosphere. We can surel y believe that successive, dynamic, systematic and multi-parameter stereoscopy observation will be a development tendency of earthquake's impending forecasting in future. Through spatial detect technique, we can real time capture the corre lative dynamic information before earthquakes. Low price, covering more area, fa ster, more information, more strong directing perception and continual observing are characteristics of application of remote sensing technology, which compensa te the inadequate of seismic stations on the ground and improve present system o f earthquake's monitoring and forecasting. There is fairly reason to trust that the short-term predicting precise degree of earthquake information must be impr oved.
