The use of cost-effective accelerometers for local seismic monitoring network

In this study, we assess a new inexpensive triaxial accelerometer prototype's seismicity detection ability using micro-electro-mechanical systems (MEMS technology). MEMS sensor networks have been set up throughout the northern Italy (Veneto region). The signals provided by OGS MEMES monitored in terms of PGA and spectral responses. The low-cost OGS MEMS sensors offer an effective characterization of the main ground motion parameters by detecting minor local events and far-off moderate earthquakes. This attests to the potential utility of the suggested accelerometer prototypes as integrated seismicity monitoring instruments within conventional networks.
