GNGTS 2019 - Atti del 38° Convegno Nazionale

GNGTS 2019 S essione 2.2 427 waveforms are clearly recognizable. The main limitation of the adopted sensors is represented by the reduced sensing capability, being the noise floor of the best MEMS accelerometer about -100 db. The self-noise of theMEMS accelerometer will be likely reduced in the next generations of sensor, so that even part of the seismic background noise could be assessed (MEMS sensors are more suitable for strong-motion seismology). A possible solution to partly overcome such limitations is to integrate the station with a compact velocimeter. A velocimeter improves the detection capability for low-energy events and could enhance the detection of the first waves arrivals for EEW purpose (Vitale 2018). The shake maps allow a rapid disaster assessment of the stricken area and could also represent the base for an automated visual inspection system and survivors research relying on remotely operated vehicles (Cannioto 2017).
