Figure 6 : Distributions of observed intensities19 and simulated ground velocities.

From: Widespread ground motion distribution caused by rupture directivity during the 2015 Gorkha, Nepal earthquake

Figure 6

(a) The Intensity distribution for the Gorkha earthquake. The white and black stars represent the main shock and largest aftershock, respectively. The blue triangle is the location of Kathmandu. The approximate rupture areas of the 2015 Gorkha and 1934 Bihar-Nepal earthquakes are outlined by solid black and dashed grey lines, respectively19 (© Seismological Society of America). (b) Maximum ground velocities simulated with voxel FEM. Red curves with triangles represent the MFT. The red star, grey rectangle, and blue triangle are the hypocentre, source fault, and Kathmandu, respectively. The inset shows the assumed velocity structure along profile X–Y. (c) Ground velocities simulated with the assumed velocity structure (upper red traces) or the modified velocity structure (upper blue traces). Their Fourier spectra are also shown in the lower half. The map was generated using Generic Mapping Tools40 4 (http://gmt.soest.hawaii.edu/).
