Interplay of tectonic and dynamic processes shaping multilayer extensional system in southern-central Apennines.

High-hazard seismic zones can remain silent over centuries with meager seismicity rates challenging our understanding of seismic processes. We focus on the comprehensive analysis of cascading episodes of swarms and seismic sequences following the 2009 L'Aquila mainshock (M 6.3) in the southern-central Apennine that previously experienced ~ M7 earthquakes.

Seismicity at the Castor gas reservoir driven by pore pressure diffusion and asperities loading.

The 2013 seismic sequence at the Castor injection platform offshore Spain, including three earthquakes of magnitude 4.1, occurred during the initial filling of a planned Underground Gas Storage facility. The Castor sequence is one of the most important cases of induced seismicity in Europe and a rare example of seismicity induced by gas injection into a depleted oil field.
