One heavy earthquake with MS8.0 occurred on May 12, 2008 in Wenchuan County, Sichuan province. After the earthquake, almost all the space-bornandair-born remote sensing facility in China were used to monitor the serious disaster. There are four important functions which include disaster situation quick report, spatial information support, dynamic monitoring of secondary disasters and reconstruction planning that remote sensing has took. Through the war between human and earthquake, a lot problem about remote sensing used in natural hazard monitoring has been exposed. Lastly, the oriented development of remote sensing' s functionin natural hazard monitoring is discussed at our viewpoint.
