Abstract：The analysis of the FY-2 satellite cloud images and the infrared radiation brightness temperature data within a month before Lushan earthquake discovered that there were two linear clouds with length of hundreds of kilometers, which developed along the eastern edge of Tibet Plateau at 06:30-09:30am on 17 April, 2013, 3 days before Lushan earthquake. The earthquake epicenter of Lushan earthquake was just located at the intersection point of these two linear clouds extension. As compared to the linear cloud anomalies occurred a few hours before Wenchuan Ms 8.0 earthquake, we suggested that the abrupt occurrences of linear clouds before strong earthquakes in Longmenshan faults region might be related with some unknown hidden structures and underground petroleum resources in the eastern edge of Tibet Plateau. The linear clouds had omens meaning for coming earthquake, which should be taken as a key point of satellite remote sensing monitoring. Subsequently, with the support of big data from GEOSS, and in consideration of the interaction between the multiple spheres of earth system and coupling effect in seismogenic process, we will analyze the spatio-temporal features and the relations of multi-parameters from remote sensing, so as to provide scientific foundations for uncovering the enigma of abnormal liner clouds in this region.
