The EMERSITO seismic networks are devoted to site effect studies in different municipalities of Central Italy affected by the Mw 6.0 Amatrice earthquake (24/08/2016) and the following seismic sequence. The aim of EMERSITO is to carry out and coordinate the monitoring of local site effects, caused by geological and geomorphological settings. During the first days of the seismic emergency, EMERSITO installed a temporary seismic network for site effect studies at 4 municipalities close to the epicentral area (Amandola, Civitella del Tronto, Montereale and Capitignano), using 22 stations equipped with both velocimetric and accelerometric sensors. The selection of the sites where stations have been installed was mainly driven by the proximity to the epicentral area (without interfere with the rescue operations) and by peculiar geologic and geomorphologic settings (topographic irregularities, fault zones, alluvial plains).nData is distributed through the Orfeus European Integrated Data Archive (EIDA) federation and International Federation of Digital Seismograph Networks (FDSN) standard protocols under an open definition compliant license.
