【摘要】 以卫星热红外遥感产品的两种参数———长波辐射强度(OLR)(月际资料)和亮度温度(日际资料)为基础,对2001年11月14日昆仑山口西8.1级地震前后的卫星热红外变化特征进行了分析.结果表明,在8.1级地震发生前一个月长波辐射强度(OLR)出现增强异常;震前6～7天出现亮度温度的增强,异常现象在空间分布上呈现为条带状,与震中区的构造分布一致.更多还原

【Abstract】 Based on the two products of infrared from satellite remote sensing, i.e.. Outgoing Longwave Radiation(OLR) and Bright Temperature(BT),the precursor anomaly feature of infrared radiation before west to Kunlun Mountain Pass M8.1 earthquake on Nov.14,2001,is analyzed.The result shows that the increasing anomaly of OLR appeared since a month and BT since a week before the earthquake,and both anomalies stretched along the seismotectonic zone in the epicenter district.更多还原
