Shallow seismic structure

Imaging shallow seismic structure can help better assessment of earthquake-induced ground-shaking, more accurate construction of seismic models at depth and revealing regional geological complexiticity. A 3D Vsv shallow model extending to 8 km was constrained with the joint inversion of Rayleigh wave ellipticity and receiver function in this study.

Map view of average Vsv structure over depth range 0.5 – 1.5 km.

The thick-black lines show location of transects. The grey dashed lines enclose Tibet area and the solid circles are indicative of uninterpolated average Vsv over this depth range beneath seismic stations.
