Abstract This paper describes the seismological analyses performed within framework of seismic microzonation study for reconstruction 138 municipalities damaged by 2016–2017 sequence in Central Italy. Many waveforms were recorded over approximately 15 years at 180 instrumented sites equipped with permanent or temporary stations an area that includes all localities. Site response was assessed using earthquake and noise recordings selected through different parameters, such as spectral...
In recent years, new approaches for developing earthquake rupture forecasts (ERFs) have been proposed to be used as an input probabilistic seismic hazard assessment (PSHA). Zone- based with seismicity rates derived from catalogs are commonly in many countries the standard national models. Italy, a single zone- ERF is currently basis official model. this contribution, we present eleven ERFs, including five zone-based, two smoothed seismicity-based, fault- based, and geodetic-based, PSH model...

In this study, microseism recordings from a near coast seismic station and concurrent significant sea wave heights (|$H_{\frac{1}{3}}$|) are analysed to calibrate an empirical relation for predicting height in the Ligurian Sea. The study stems investigation of damaging storms occurred Sea between 2008 October November. Analysing data collected time frame allows identification two types signal, one associated local motion attributable remote source area. former is dominated by frequencies...
In this work, we test a fully automatic procedure to obtain local earthquake tomography (LET), starting from seismic waveforms and applying the capability of phase picker locator engine “RSNI‐Picker” (Spallarossa et al. , 2014), which is based on multistep iterative working P S arrival times. This code currently operating as part Earthquake Monitoring System at University Genoa (RSNI designates regional network northwestern Italy). particular, compare ‐ ‐wave tomographic results obtained...
In the context of environmental monitoring Concordia wreck removal project, measurements currents, winds and sea level height were made along eastern coast Giglio Island, Tyrrhenian Sea (Italy), during 2012–2013. The aim study was to investigate effect atmospheric forcing periodic sea-level changes on coastal currents. Normalised Cross-Correlation Function analysis allowed us correlate these observations. A marked inter-seasonal variability found in both current local wind velocity...

Abstract Structure and properties of the Adriatic crust were determined from local earthquake tomography around Giudicarie fault zone (central‐eastern Southern Alps, Italy). Tomographic results, based on well‐suited 436 revised earthquakes (period 1994–2007), have a resolution comparable to scale regional geological domains tectonic structures. The observed strong velocity anomalies correlate well with lithological variations corresponding different (particularly magmatic complexes at depth)...
SUMMARY On-site earthquake early warning (EEW) systems represent an important way to reduce seismic hazard. Since these are fast in providing alert and reliable the prediction of ground motion intensity at targets, they particularly suitable areas where seismogenic zones close cities infrastructures, such as Central Italy. In this work, we use Gradient Boosting Regressor (GBR) predict peak acceleration (PGA), hypocentral distance (D) starting from P-wave features. We two data sets waveforms...
Abstract. The micro-electromechanical system (MEMS)-based seismic network of Trentino (NE Italy) consists 73 low-cost accelerometers installed close to inhabited areas. These sensors have a suitable sensitivity detect moderate-to-strong earthquakes but are able record even weaker seismicity. densely distributed peak ground acceleration values recorded by MEMS and other types stations integrated within the existing monitoring procedure in order automatically obtain complete set strong motion...
Abstract The earthquake swarm that took place in 2012–2015 the Upper Ubaye Valley (the most active seismic zone French Alps) is peculiar for two reasons: (1) it occurred a few kilometers from previous (active 2003–2004); (2) it was initiated by an M L 4.3 shock and reactivated, more than years later, another 4.8 with identical epicenter but deeper focus. We present here corresponding data set of ∼13,000 events, which ∼3000 were relocated using double‐difference algorithm. extends...
Abstract The protracted nature of the 2016-2017 central Italy seismic sequence, with multiple damaging earthquakes spaced over months, presented serious challenges for duty seismologists and emergency managers as they assimilated growing sequence to advise local population. Uncertainty concerning where when it was safe occupy vulnerable structures highlighted need timely delivery scientifically based understanding evolving hazard risk. Seismic assessment during complex sequences depends...
This work presents seismic strain rate maps for the Western Alps and Northern Apennines (northern Italy) as derived from an earthquake catalog collecting both historical instrumental data. Strain rates are calculated on basis of moment release using Anderson method. Unlike previous applications, which determined total associated with specific seismogenic sources, we have employed innovative zoneless approach based a spatially smoothed seismicity In addition, Monte Carlo simulation procedure...
Since the beginning of 1980s, when Mandelbrot observed that earthquakes occur on 'fractal' self-similar sets, many studies have investigated dynamical mechanisms lead to self-similarities in earthquake process. Interpreting seismicity as a process is undoubtedly convenient bypass physical complexities related actual Self-similar processes are indeed invariant under suitable scaling space and time. In this study, we show long-range dependence an inherent feature seismic process, universal....
