Several strong-motion seismograms recorded at 8 km from a large nuclear test at Pahute Mesa, Nevada Test Site, are modeled using the Cagniard-de Hoop technique. The ratio of vertical to radial motions suggest that the peak values are produced by ray paths that penetrated to a depth several kilometers below the source. A homogeneous layered Earth model with velocity increasing with depth was use...

The first model of two layers is presented to study the anisotropy pattern beneath Myanmar and Thailand using shear-wave splitting. Teleseismic activity recorded by 15 permanent broadband stations was analysed investigate understand flow direction in mantle. speed were observed forms fast polarisation (

Receiver functions derived from teleseismic body waves recorded by ocean-bottom seismometers on the southern East Pacific Rise reveal shear waves converted from compressional waves at the mantle discontinuities near 410- and 660-kilometer depth. The thickness of the mantle transition zone between the two discontinuities is normal relative to the global average and indicates that upwelling benea...

We investigated the similarities and differences between rupture processes of 1952 2003 Tokachi-oki earthquakes (Mw ∼ 8) that occurred 51 years apart in southernmost region Kuril subduction zone. This event pair is rare because seismic waveforms both events were instrumentally recorded. performed joint source inversion analyses to better understand this earthquake sequence. The dataset for cons...
