Description:
On December 26, 2018, a Mw 4.9 earthquake hits the eastern
flank of Mount Etna volcano (Sicily). The epicenter is located between
the Fleri and Pennisi villages, and focal depth is estimated at 0.3 km
(http://cnt.rm.ingv.it/event/21285011). This earthquake is part of a
seismic sequence begun on December 23, 2018 and a concurrent phase of
volcanic eruption, eventually resulting in lava flows and a dyke
intrusion (De Novellis et al., 2019).The earthquake is the result of the
activation of the Fiandaca Fault; it is accompanied by widespread
surface faulting and secondary environmental effects (Emergeo Working
Group, 2019; Figs. 1 - 3), and have a maximum intensity of VIII EMS
(Quest WG, 2019).Partial or complete ruptures of the Fiandaca Fault are
well-documented in the last 150 years (Fig. 1). The last event that
activated the entire structure, as happened in 2018, occurred in 1894
and generated extensive surface faulting and secondary effects (Riccò,
1894; Baratta, 1894; Imbò, 1935).Despite the abundant documentation of
previous events, the Fleri earthquake represents the first opportunity
to document coseismic effects of a strong, shallow seismic event at Mt.
Etna through modern field techniques, sustained by accurate
remote-sensed data, including unprecedented InSar measurements.
