Back-projection results
(Ocean Hemisphere Research Center: Wang Dun )
Figure 1 Station map for the European regional array (left), China array (middle), and Hi-net (right). The Focal mechanism is determined by the GCMT. Solid and dashed lines show the epicenter distances and strikes of the nodal planes, respectively.Figure 2 Colorful squares indicate the timings and amplitudes of the stack with the maximum amplitude at each time step (2s) derived from data recorded at three arrays in Europe, China, and Japan (Hi-net) filtered between 0.05 and 0.5 Hz. The gray and black circles show the previous seismicity and aftershocks (one day after the origin time). Gray dashed lines show the plate boundary between Indian plate and Eurasian plate. The red triangle indicates the location of capital city Kathmandu.
