Abstract
During restoration operations at the former Convent of San Benedetto in Corso Porta Po, in Ferrara (Italy), an unexploded aeroplane bomb from War World II (WWII) was found on the first floor of the church (see e.g., press release from the Prefecture (Prefettura - Ufficio territoriale del Governo di Ferrara 2023). In the morning of 26 November 2023 the bomb was removed from this location and later, at 14:19 (UTC), a controlled detonation of the war device was performed in a cave about 7 km NW of the city. The cave where the explosion occurred is located in an area in which a local seismic monitoring network, the SNet4Fer 3.0, operates for monitoring microseismicity around the Casaglia geothermal field (Fig. 1). SNet4Fer 3.0 is an evolution of the previous SNet4Fer 2.0 network, which is still in operation, and represents an improvement of the monitoring capabilities of the anthropogenic activities that can potentially induce seismicity in the geothermal field (Abu Zeid et al., 2017). Both networks are operated by the University of Ferrara.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
