- Abstract
The MEMS-based seismic network of Trentino (NE Italy) consists of 76 low-cost accelerometers installed close to inhabited areas. These sensors have a suitable sensitivity to detect moderate-to-strong earthquakes but are able to record even weaker seismicity. The densely distributed peak ground acceleration values recorded by MEMS and other types of stations are integrated within the existing seismic monitoring procedure in order to automatically obtain a complete set of strong motion parameters a few minutes after the origin time. The exposure for resident population and critical buildings is estimated by quantifying the different levels of shaking, which is expressed according to the Mercalli-Cancani-Sieberg intensity scale. These types of results, summarized in synthetic PDF (Portable Document Format) documents, can be useful for civil protection purposes to timely evaluate the state of emergency after a strong earthquake and to choose how and where activate first aid measures and targeted structural monitoring.
