Horizontal-to-vertical Fourier spectral ratio curves (HVSR) for velocimetric (vel) and accelerometric stations (acc), obtained considering 24-h background noise. DOSS and DVSC curves are highlighted (cf. Fig. 2). The gray box delimits the area with HVSR equal to 2, according to SESAME Working Group (2004) guidelines (see text for comments)

An application of the Complete Automatic Seismic Processor (CASP) for seismic monitoring is presented. Its integrated and iterative fully automatic procedure is able to achieve complete data analysis and significantly rapid elaborations. Its performance in real-time seismic monitoring and alerting is tested in the Trentino region (NE Italy) for the...

Morrow point arch dam is a typical arch dam representing many realistic arch dams constructed in different regions. A dynamic analysis of the 3D model of the morrow point arch dam with and without water is presented for the Kern county earthquake (1952). The analysis is performed in ABAQUS, in which a complete hydrodynamic effect is included in the...

Seismic effect to the tunnel form building (TFB) will vary depending on the location of the epicentre, magnitude and frequency of the seismic event. This effect can be mitigated by implementing a seismic analysis using the Ruaumoko 2D programme. The seismic analysis was conducted to examine the safety level of the TFB when it was subjected to 10 pr...

... The Trentino region (NE Italy) is currently monitored by a permanent seismic network, which has been managed by the Autonomous Province of Trento (PAT) since 1981 (Geological Survey-Provincia Autonoma di Trento, 1981;Viganò et al., 2021;Fig. 1). ...
... In the case of the Trentino region, a fully automated earthquake monitoring system is already operating based on CASP (Viganò et al., 2021). Thus, the great amount of data provided by the 73 installed MEMS stations (starting date July 2022; Fig. 1) has easily been integrated within the seismic monitoring procedure as the only requirements for CASP are real-time data transmission in standard SeedLink format and station response metadata in seismological standard format (i.e. ...

The micro-electromechanical system (MEMS)-based seismic network of Trentino (NE Italy) consists of 73 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 of the 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 portable document format (PDF), can be useful for civil protection purposes to evaluate the state of emergency after a strong earthquake in a timely manner and to choose how and where to activate first aid measures and targeted structural monitoring.
