Description:
The main goal of this study is to provide moment tensor solutions for small and moderate earthquakes
of the Matese seismic sequence in southern Italy for the period of December 2013–January 2014. We
estimate the focal mechanisms of 31 earthquakes with local magnitudes related to the Matese earthquake
seismic sequence (December 2013–January 2014) in Southern-Central Italy which are recorded by
the broadband stations of the Italian National Seismic Network and the Mediterranean Very Broadband
Seismographic Network (MedNet) run by the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The
solutions show that normal faulting is the prevailing style of seismic deformation in agreement with the
local faults mapped outin the area. Comparisons with already published solutions and with seismological
and geological information available allowed us to properly interpret the moment tensor solutions in the
frame of the seismic sequence evolution and also to furnish additional information about less energetic
seismic phases. Focal data were inverted to obtain the seismogenic stress in the study area. The results
are compatible with the major tectonic domain of the area.
