The determination of the crustal structure is essential in geophysics, as it gives insight into the geohistory, tectonic environment, geohazard mitigation, etc. Here we present the latest advance on three-dimensional modeling representing the Tibetan Mohorovičić discontinuity (topography and ranges) and its deformation (fold), revealed by analyzing gravity data from GOCE mission. Our study show...

the central alborz mountains of northern iran (figure 1) is a zone of intense active continental deformation and is the most heavily populated region of iran, including the mega-city of tehran with a population of over 10 million. the region is affected by numerous active faults, some of them having great seismic potential, and documented historical seismicity. hence, the central alborz is a pr...

A cooperative program of seismic refraction profiling was completed in the vicinity of the Puerto Rico Trench by Hudson Laboratories, Woods Hole, Lamont, and Texas A. & M. Profiles completed near the western end of the Trench were analyzed at Hudson Laboratories. Five seismic layers are indicated below the water layer. The thickness/velocity relationships are as follows: 5.1 km of 1.5 km/sec. (...

In Table S1, we provide information on the events we used for the receiver functions (RFs). The time-axis RFs are shown in Figure S1. With Figure S2 and Text S1, we derive the relationship between the change in estimated Moho depth and the change in the Vp/Vs ratio used in the reference model to convert Ps arrival time to depth. With Figure S3 and Text S2, we rationalize our observation of posi...

A total of 336 three-component strong-motion recordings from the Mw 6.35 Niu Dou earthquake of 25 June 1995 at a focal depth of 39.9 km in northern Taiwan are used to study the effects on strong ground motion due to Moho reflection of S waves. The residuals of both horizontal peak ground acceleration (PGA) and peak ground velocity (PGV) recorded from the earthquake are analyzed. The results con...
