ABSTRACT

Modern seismic ground‐motion sensors reached excellent response quality in terms of dynamic and bandwidth resolution. The weakest point in the recording of the strong‐motion wavefield is the spatial sampling and resolution, due to the limited number of installed sensors, often at large distances. A significant improvement in spatial resolution can be achieved by the use of low‐cost distributed sensors arrays, capable of recording seismic events with a dense sensors network. In this perspective, microelectro mechanical system (MEMS) sensors could efficiently integrate the use of standard accelerometers for moderate‐to‐strong seismic events. In this article, we present data from the 2016 Central Italy earthquakes, recorded by a spatially dense prototype MEMS array installed in the neighborhood of the epicenter area. MEMS records are compared against the national strong‐motion network data, suggesting that these very low‐cost sensors could be an effective choice for increasing the spatial density of stations to provide strong‐motion peak parameters.
