The CEDIT catalogue, Italian acronym of Catalogue of Earthquake-Induced
Ground Effects, is available since 2011. After the Mw 6.0
Amatrice (Italy) earthquake (occurred at 01:36:32 UTC on 24th August,
2016) this catalogue was updated with 147 new inventoried ground effects.
Since the first hours after the mainshock, field works and targeted
remote sensing analyses were performed for recognizing and inventorying
earthquake-induced ground effects. To avoid an inextricable overlap
of ground effects due to either earthquake or rainfall events, intensive
field activities were carried out and completed within a week, hence before
the first intense rainfalls occurred on 30th of August. Ground effects
mainly consist of landslides, in particular rock-falls and rock- and debris-slides,
whereas less than 2% of the effects consist of ground cracks
not directly related to landslides. The maximum distance from the
epicenter of the surveyed ground effects is about 36 km, though more
than 50% of the effects occurred within 20 km. The plano-altimetric
distribution of ground effects is rather conditioned by the presence of
road cuts, as well as by local natural hillslope topographic and morphological
setting. The 73% of the triggered landslides intercepted road-cuts
and accounted for significant interference with local traffic and emergency
activities. The altimetric distribution of the ground effects covers a
range of about 1000 m (from 600 up to 1600 m a.s.l.), emphasising that
the ground effects involved the outcropping rock masses in different
topographic conditions. Moreover, the homogeneous distribution of the
ground effects into the different outcropping lithological units suggests
that lithology did not play a principal role as predisposing factor for the
earthquake-induced slopes failures occurred in the area. This work presents
the methodological approach used for efficiently recognizing and
inventorying ground effects triggered by the 24th August 2016 (Mw 6.0)
Amatrice earthquake, as well as for managing and sharing results online
on a global, pre-existing and public geo-database
