A high-quality data set for seismological studies in the East Anatolian Fault Zone, Türkiye Open
This work aims to develop and share a high-quality seismic data set for the East Anatolian Fault Zone (EAFZ), a highly active seismic area that is prone to earthquakes, as evidenced by the two major earthquakes of magnitude 7.8 and 7.6 tha…

Temporal variation of <i>S</i>-wave attenuation during the 2009 L'Aquila, Central Italy, seismic sequence Open
SUMMARY We investigate temporal and spatial variations of the spectral decay parameter kappa (κ) before and after the 6 April 2009, L'Aquila earthquake (Mw 6.1), in Central Italy. We analysed foreshocks 10 days before and aftershocks occur…

The advantages of Standardization and Data Sharing: a swift compilation of a high-quality data set for seismological studies in the East Anatolian Fault Zone Open
On 6 February 2023 at 01:17 UTC, the Mw 7.8 Pazarcık earthquake struck south-eastern Türkiye and Syria along the East Anatolian Fault Zone (EAFZ), in the province of Kahramanmaraş. The Mw 7.6 Elbistan earthquake occurred abo…

Physics-based parametrization of a FAS nonergodic ground motion model for Central Italy Open
We propose a new fully nonergodic ground motion model for Central Italy, which is one of the most sampled areas in the world after the occurrence of the last seismic sequences of 2009 and 2016–2017. The model predicts 69 ordinates of the F…

Evidence of frequency-dependent directivity effects from non-ergodic ground motion modelling of Spectral Acceleration in Central Italy Open
Rupture directivity and its potential frequency dependence is an open issue in the seismological community, especially for small-to-moderate earthquake. Directivity itself is the focusing of the radiated seismic wave energy due to the rupt…

Empirical Evidence of Frequency‐Dependent Directivity Effects From Small‐To‐Moderate Normal Fault Earthquakes in Central Italy Open
Rupture directivity and its potential frequency dependence is an open issue within the seismological community, especially for small‐to‐moderate events. Here, we provide a statistical overview based on empirical evidence of seismological o…

A new inversion method to construct a 3-D crustal shear-wave velocity model from P-to-S converted waves and application to the Central Alps Open
<p>We developed a new method where teleseismic P-to-S converted waves are used to construct a fully 3-D shear-wave velocity model of the crust. The method differs from ambient noise and local earthquake tomography in its ray-paths be…

Converted wave tomography: Developing a new inversion method for 3-D crustal shear wâve velocities, with application to the Central Alps Open
Passive seismological investigations typically image the Earth’s crust with direct P-waves or ambient noise correlation yielding S-wave information. While the first method requires local earthquakes to achieve high resolution, in the second…
