We present the results of studies of seismicity in the Reggio Emilia area (Northern Italy). The Istituto Nazionale di Geofisica instrumental earthquake catalogue (1975-1996) reported about three moder...
Investigating the time dynamics of geoelectrical signals measured in two seismotectonic environments in the Mediterranean region: the Southern Apennine chain (Southern Italy) and the Hellenic arc (Crete Island, Greece)

In this paper we explore the time dynamics of geoelectrical signals measured in two seismic active areas in the Mediterranean region: the Southern Apennine chain (Italy) and the Hellenic arc (Crete Is...

Geophysical evidence shows the presence of low-seismic velocity material at the surface of slabs in subduction zones. In the central Mexican subduction zone this appears as a thin (~4 km) low-velocity...
Spectral‐element simulations of long‐term fault slip: Effect of low‐rigidity layers on earthquake‐cycle dynamics
Spectral‐element simulations of long‐term fault slip low‐rigidity layers earthquake‐cycle dynamics

2014/4/8
We develop a spectral element method for the simulation of long‐term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.
Our approach reproduces all stages of ...

Our understanding of mantle convection and the motion of plates depends intimately on our understanding of the viscosity structure of the mantle. While geoid and gravity observations have provided fun...

We collected data from a transect of continuous GPS sites across the eastern Basin and Range province at latitude 39◦N from 1997–2000. Intersite velocities define a region~350 km wide of broadly...
