Impact of Mantle Velocity Uncertainty on Receiver‐Function Imaging of the Transition Zone

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Seismological estimates of the 400‐km and 670‐km mantle discontinuities (d400 and d670) are crucial for understanding the thermochemical structure and dynamics of the mantle transition zone (MTZ). However, artifacts from using ray theory and uncertainties in mantle velocity structure can affect topographic mapping of these boundaries.

Impulsive supply of volatile-rich magmas in the shallow plumbing system of Mt. Etna volcano [PDF]

open access: yes, 2018
Magma dynamics at Mt. Etna volcano are frequently recognized as the result of complex crystallization regimes that, at shallow crustal levels, unexpectedly change from H2O -undersaturated to H2O-saturated conditions, due to the impulsive and irregular ...

Seismic Attenuation Reveals Fault and Forearc Structure Across the Subduction‐Collision Transition in Southern Taiwan

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Southern Array for the Lithosphere and Uplift of Taiwan Experiment (SALUTE) provides a new window into the subduction‐collision transition zone in southern Taiwan, where the Eurasian Plate‐Luzon Arc convergence drives intense orogeny and crustal deformation. Using dense P‐ and S‐wave spectral amplitude data recorded by SALUTE and a quality

Moho Depth Variations in Central Italy

open access: yes, 2013
[1] Along the Italian peninsula adjoin two crustal domains, peri-Tyrrhenian and Adriatic, whose boundary is not univocal in central Italy. In this area, we attempt to map the extent of the Moho in the two terrains from variations of the travel time difference between the direct P wave and the P-to-S wave converted at the crust-mantle boundary, called ...

U and Th content in the Central Apennines continental crust: a contribution to the determination of the geo-neutrinos flux at LNGS

open access: yes, 2011
The regional contribution to the geo-neutrino signal at Gran Sasso National Laboratory (LNGS) was determined based on a detailed geological, geochemical and geophysical study of the region.

The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes. Ultraslow velocity layers (USVLs) along the megathrust are commonly interpreted as indicators of elevated pore‐fluid pressures that promote slow slip, but their temporal variability ...

Three‐dimensional Moho topography in Italy: New constraints from receiver functions and controlled source seismology

open access: yesGeochemistry, Geophysics, Geosystems, 2011
In complex tectonics regions, seismological, geophysical, and geodynamic modeling require accurate definition of the Moho geometry. Various active and passive seismic experiments performed in the central Mediterranean region revealed local information on

Moho Interface Modeling Beneath the Himalayas, Tibet and Central Siberia Using GOCO02S and DTM2006.0

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2013
We apply a newly developed method to estimate the Moho depths and density contrast beneath the Himalayas, Tibet and Central Siberia. This method utilizes the combined least-squares approach based on solving the inverse problem of isostasy and using the ...

Tectonic evolution of a continental collision zone: A thermomechanical numerical model [PDF]

open access: yes, 2004
We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale visco-plasto-elastic thermomechanical model that has a free upper surface, accounts for erosion and deposition
