This paper describes the damage survey in the city of L’Aquila after the 6 April
2009 earthquake. The earthquake, whose magnitude and intensity reached Mw=6.3 and
Imax=9–10 MCS, struck the Abruzzi region of Central Italy producing severe damage in
L’Aquila and in many villages along theMiddle Aterno River valley. After the event, a building-
to-building survey was performed in L’Aquila downtown aiming to collect data in order
to perform a strict evaluation of the damage. The survey was carried out under the European
Macroseismic Scale (EMS98) to evaluate the local macroseismic intensity. This damage survey
represents the most complex application of the EMS98 in Italy since it became effective.
More than 1,700 buildings (99% of the building stock) were taken into account during the
survey at L’Aquila downtown, highlighting the difficult application of the macroseismic scale
in a large urban context. The EMS98 revealed itself to be the best tool to perform such kind
of analysis in urban settings. The complete survey displayed evidence of peculiar features in
the damage distribution. Results revealed that the highest rate of collapses occurred within
a delimited area of the historical centre and along the SW border of the fluvial terrace on
which the city is settled. Intensity assessed for L’Aquila downtown was 8–9 EMS.
