The epicenter was near village Finale Emilia where macroseismic intensity assessed 7 EMS98 [Tertulliani et al. this issue], while closest accelerometric station, MRN, located less than 20 west-ward Mirandola (Figure 1) recorded peaks ground accelerations about 300 cm/s2 (www.protezionecivile.gov.it/resources/cms/documents/Report_DPC_1_Emilia_EQSd.pdf). mainshock triggered liquefaction phenomena few kilometers eastwards epicenter, around San Carlo. same day, two other shocks 5.1 followed (02:07, 13:18 GMT; http://iside.rm.ingv.it/). 29, 07:00 UTC another 5.8 hit region with 1). Three strong aftershocks afterwards, 5.3 (May 10:55), 5.2 11:00) (June 3, 19:20).
