| 英文摘要 | The area of west Sichuan and east Tibet is the channel where the deep materials of the Tibetan plateau flow eastward and turn to southeast Due to the strong differentiation, adjustment and movement of the deep materials in this area, strong tectonic activities and earthquakes occur frequently here Hence, a profile across the Tethyan tectonic domain and the Yangzi craton has been set along the 30 degrees N latitude And the theoretical isostatic crustal thickness has been calculated according to the Airy isostatic theory and compared with the crustal thickness obtained from both the active and passive seismic sounding data, so as to discuss the isostatic state of the area The result reveals that there exist two non-isostatic regions along this profile, that is to say, compared with the stable Sichuan basin, the crusts of these two regions are in quite a non-isostatic state Based on this result, we have analyzed and discussed the relationship between isostatic anomaly and the distribution of strong earthquakes Our result suggests that the non-isostatic area is the main zone where strong earthquakes occur frequently, and the steep gradient belt of the non-isostatic zone is the place worth more attention concerning earthquake prediction |
