In an attempt to provide, for the first time, a comprehensive view of the seismicity in the area, this study describes the main characteristics of the database collected by the RSNI network. The seismicity is spread almost over the entire area, but it is mainly concentrated in the Northern Apennines and in the western sector of the Alps. The seismicity of the area is superficial: It is almost confined to the first 20 km of depth. Only a few deeper events are located in a small area southwest of the city of Turin, down to a depth of 80 km, and below the Northern Apennines down to 60-70-km depth. The majority of the earthquakes in this sector of the Italian peninsula are of low magnitude; nevertheless, the areas where the highest magnitude earthquakes took place during the last three decades are the Northern Apennines and the lower Piedmont, on land, and the Ligurian Sea, offshore. They are indeed the areas where the most damaging historical earthquakes have occurred, giving emphasis, if necessary, to the importance of continuous seismic monitoring.

The vast volumes of seismic data being recorded by both permanent and temporary networks operating all over the world provide exciting opportunities for studying the Earth’s interior and earthquake source characteristics. As a result, the development of efficient computer algorithms and procedures capable of automatically extracting and processing such long streams of data is one of the most challenging issues facing modern seismological research. Valoroso et al. (2013) obtained an extraordinary degree of detail in the anatomy of the normal‐fault system of the l’Aquila earthquake after processing around 64,000 aftershocks (extracted, picked, and located) via an automated procedure. Spectral analysis of K‐NET and KiK‐net data in Japan was carried out by Oth et al. (2011) on the basis of more than 67,000 records analyzed via an automated procedure that included phase picking, earthquake location, and coda identification. The key elements of any automatic procedure devoted to exploiting the full potential of travel‐time‐based methods such as earthquake location and seismic tomography are (1) arrival‐time determination, (2) quality assessment, and (3) outlier detection. In recent decades, several new automatic picking algorithms have been developed, with the aim of processing large amounts of data for (near‐) real‐time seismic signal analysis. These algorithms are generally classified according to the adopted phase‐detection scheme: (1) short term average to long term average ratio (STA/LTA)‐based algorithms (Allen, 1978, 1982; Baer and Kradolfer, 1987; Lomax et al. , 2012), (2) autoregressive methods (Leonard and Kennet, 1999; Sleeman and van Eck, 1999; Leonard, 2000; Kuperkoch et al. , 2012), (3) Akaike information criterion (AIC; Akaike, 1974)‐based algorithms (Maeda, 1985; Turino et al. , 2010), (4) methods based on neural networks (Dai and MacBeth, 1995; Zhao and Takano, 1999; Gentili and Michelini, 2006 …

The possibility to predict sea wave heights in the Ligurian Sea is analyzed in this study using about a month of observations from both seismic recordings from a near-coast station (IMI - Imperia Monte Faudo) and significant sea wave heights measured from a buoy (Côte d'Azur buoy, Météo-France network). We focus on the analysis of the vertical component of microseism, which reveals a strong correlation with measured sea wave heights. Looking at the amplitude spectrogram of the vertical component of microseism, we recognize the effects of several meteo-marine events that can be ascribed to Atlantic barometric pressure lows and a series of sea storms in the Ligurian Sea. Moreover, the distinction between primary and...
