Abstract


Large earthquakes are a huge disaster for humanity. Monitoring, the study of earthquakes is one of the important ways of reducing geological disasters. The important role of satellite remote sensing monitoring techniques in earthquake monitoring and research. Development of recent years, high spectral resolution satellite remote sensing technology, so that we can get more updated seismic gas geochemistry, seismic activity to explore and predict the spatial location of future earthquakes. May 12, 2008 Wenchuan MS 8.0 earthquake extracted using high-resolution satellite remote sensing data (AIRS), April 4, 2010, Baja California, Mexico MW 7.2 and April 14, 2010 the Qinghai Yushu MS 7.1 earthquake around the epicenter near the CO total and CO volume mixing ratio, CH4 and CO2 volume mixing ratio, H2O and O3 total data changes over time, and to discuss the relationship between CO, H2O gas geochemical changes and seismic activity. For a major earthquake occurred in three different geographical environment, through the processing of high-resolution satellite remote sensing data, obtained following the earthquake-related gas geochemistry and temperature anomalies: (1) after the Wenchuan earthquake epicentral area CO total peak main shock and aftershocks Correspondingly. (2) about a month before the California earthquake CO total increased over the same period the average 4 x 10 17 mole/cm2 higher than the previous two years, before and after the earthquake the total amount of CO and near-surface CO volume mixing ratio fluctuation phenomena, and 8, the standard deviation of the average data increases, approximately 2 times the non-earthquake period. (3) the total amount of water vapor after the main shock of the earthquake in Yushu significantly higher than the first two years of the average, before and after the earthquake in Yushu CO increased change in total. MODIS L1B data inversion temperature data before and after the earthquake in Yushu in brightness temperature surface temperature before the main shock with high values, abnormal high value higher than the same period in the years before the earthquake, the average temperature distribution along the NW-trending fault zone; Yushu area temperatures measured 3 4 month higher than before the earthquake 10 years the average temperature for the same period in the same phenomenon. Inversion results and seismic geological data showed that the abnormal changes of these parameters before and after the big earthquake might seismogenic ground stresses in the lithosphere degassing occurred process enhanced the underground gas along active fault zones fugitive caused seismic activity caused by changes in atmospheric chemistry. The research results show that the use of high-resolution satellite remote sensing data to extract the earthquake-related surface temperature, humidity and atmospheric trace components (CO) content of the temporal and spatial variation important information on earthquake monitoring and forecasting.
