Abstract | On Nov. 18 at 06,34 CST time, an M6. 9 earthquake occurred at Mainling prefecture, Nyingchi City, Tibet. This earthquake is located close to the northeastern corner where the Indian plate underthrusts beneath the Eurasian plate. Here the crustal shortening and the tectonically rotated deformation are the strongest with respect to other areas along the whole Himalayan orogenic belt. In this study, we recalculate the location and origin time of this earthquake based on waveforms and arrival times recorded by local and teleseismic networks. The resulting focal depth is 7 km +/- 2 km beneath the sea level (10 km +/- 2 km beneath the surface), and the epicenter is (29. 87 degrees N +/- 0. 01 degrees N, 95. 02 degrees E +/- 0. 01 degrees E). In combination with other previous geophysical and geological studies, we infer that this earthquake occurred on the NNW-trending Xixingla fault. The major tectonic features for this region are the NE-dipping thrust beneath the Namche Barwa syntaxis combined with the lateral extrusion and southeastern escape beneath the Tibetan plateau. |
