A robust knowledge of seismic anisotropy beneath the continents is essential to our
understanding of plate tectonic theory, as anisotropy provides a unique constraint on the …

The lower boundary of the lithospheric plates has remained as an enigmatic boundary for
seismologists, since it is relatively poorly observed by seismic means. There is traditionally a …

The asthenosphere plays a fundamental role in present-day plate tectonics as its low
viscosity controls how convection in the mantle below it is expressed at the Earth's surface …

The breakup of the supercontinent Gondwanaland into Africa, Antarctica, Australia and India
about 140 million years ago, and consequently the opening of the Indian Ocean, is thought …

The rocks of the Indian subcontinent are last seen south of the Ganges before they plunge
beneath the Himalaya and the Tibetan plateau. They are next glimpsed in seismic reflection …

Seismic S-wave receiver functions (SRF) are a uniquely powerful tool for imaging velocity
discontinuities within the upper mantle. SRF data frequently contain negative phases at …

A non-linear Bayesian Monte-Carlo method is presented to estimate a Vsv model beneath
stations by jointly interpreting Rayleigh wave dispersion and receiver functions and …

The earliest evidence for subduction, which could have been localized, does not signify
when plate tectonics became a global phenomenon. To test the antiquity of global …

Exhumation of ultra-high pressure metamorphic rocks testifies that the continental crust can
subduct to significant depth into the mantle despite its buoyancy. However, direct …

Seismic and geodetic observations in subduction zone forearcs indicate that slow
earthquakes, including episodic tremor and slip, recur at intervals of less than six months to …
