Calculation of the local rupture speed of dynamically propagating earthquakes
Annals of Geophysics, 2014 The velocity at which a propagating earthquake advances on the fault surface is of pivotal importance in the contest of the source dynamics and in the modeling of the ground motions generation.

Post-Perovskite Phase Transition in the Pyrolitic Lowermost Mantle: Implications for Ubiquitous Occurrence of Post-Perovskite Above CMB [PDF]
, 2022 We conducted in situ high-pressure and -temperature X-ray diffraction measurements of a pyrolitic mantle material up to 4480 K at 122–166 GPa in a laser-heated diamond anvil cell. Results demonstrate that the phase transition between bridgmanite and post-

Magneto-seismological insights into the penumbral chromosphere and evidence for wave damping in spicules [PDF]
, 2014 Aims: The observation of propagating magneto-hydrodynamic kink waves in magnetic structures and measurement of their properties (amplitude, phase speed) can be used to diagnose the plasma conditions in the neighbourhood of the magnetic structure via ...

Deterministic broadband ground motions for the 1905 Kangra earthquake using multiscale source model
Natural Hazards ResearchThe 1905 Mw 7.8 Kangra earthquake was a catastrophic event in Himalayan history, which caused widespread destruction in the near-fault region. This great historical earthquake remains inadequately understood due to the lack of instrumental data.

Computational Earthquake Seismology
Our Computational Earthquake Seismology group (CES) works on topics related to the physics of earthquakes and their consequences, Earth’s internal structure, and geothermal energy systems – frequently using high-performance computing facilities (e.g ...

Rupture mode preferences of crustal earthquakes in Japan
Earth, Planets and SpaceRupture propagation is controlled by the energy balance between the energy release rate and fracture energy, which varies according to the rupture mode.

Shear-velocity structure, tectonics and volcanism of the Tyrrhenian Sea: mantle (de)hydration of a back-arc basin [PDF]
, 2014 The Tyrrhenian Sea in the Mediterranean formed as the result of roll-back of the Adriatic and Ionian subducting plates. It is mostly underlain by strongly thinned continental lithosphere, but contains two small oceanic basins in the southern Tyrrhenian ...

Solid-state mantle convection coupled with a crystallising basal magma ocean
Comptes Rendus. GéoscienceFractional crystallisation of a basal magma ocean (BMO) has been proposed to explain the formation of large scale compositional variations in the mantle and the persistence of partially molten patches in the lowermost mantle. We present a complete set of
