Influence of Fluids and Geological Setting on Source Parameters of the 2010–2014 Pollino (Italy) Seismic Swarm Open
We analyse variations in Brune stress drop (Δ σ ), apparent stress ( τ a ) and Savage–Wood radiation efficiency ( η sw = τ a /Δ σ ) during the 2010–2014 Pollino seismic swarm (Southern Apennines, Italy). This prolonged sequence included mu…

Investigating Spectral Estimates of Stress Drop for Small to Moderate Earthquakes With Heterogeneous Slip Distribution: Examples From the 2016–2017 Amatrice Earthquake Sequence Open
Estimates of spectral stress drop are fundamental to understanding the factors controlling earthquake rupture and high frequency ground motion, but are known to include large, poorly‐constrained uncertainties. We use earthquakes from the 2…

Geodynamics, geophysical and geochemical observations, and the role of CO2 degassing in the Apennines Open
An accurate survey of old and new datasets allowed us to probe the nature and role of fluids in the seismogenic processes of the Apennines mountain range in Italy. New datasets include the 1985–2021 instrumented seismicity catalog, the com…

Spatio-temporal variations of source parameters in the nucleation zone of the 6 April 2009, Mw 6.1 L'Aquila Earthquake Open
<p>We present the results of Brune stress drop (∆σ) and apparent stress (τa) variability of  earthquakes located in a small zone adjacent to the hypocenter of the damaging Mw 6.1 L'Aquila earthqua…

Rupture Directivity of the Strongest 2016–2017 Central Italy Earthquakes Open
The along‐strike rupture directivity of 16 of the strongest earthquakes (4.4 ≤ M w ≤ 6.5) within the 2016–2017 central Italy seismic sequence is estimated by investigating high‐frequency S wave amplitude variations versus source azimuths w…

Along-strike rupture directivity of earthquakes of the 2009 L'Aquila, central Italy, seismic sequence Open
We perform a systematic investigation of along-strike rupture directivity of 70 earthquakes (3.0 ≤ Mw ≤ 6.1) of the 2009 L'Aquila seismic sequence by analysing azimuthal variations of broad-band seismograms recorded in the distance range 6…
