“…rm.ingv.it/tdmt, last access: 1 August 2019), exhibit normal faulting consistent with the tectonic regime of the area (Galadini et al, 2000). The Central Apennines are characterized by a Quaternary NE-SW oriented extensional regime (Boncio and Lavecchia, 2000;Mantovani et al, 2019). The kinematic pattern, inferred from the continuous GPS stations (e,g, Cenni et al, 2012), confirms that these extensional tectonic processes are still active.…”

Abstract. Modern seismic ground-motion sensors have reached an excellent performance quality in terms of dynamic range and bandwidth resolution. The weakest point in the recording of seismic events remains spatial sampling and spatial resolution, due to the limited number of installed sensors. A significant improvement in spatial resolution can be achieved by the use of non-conventional motion sensors, such as low-cost distributed sensors arrays or positioning systems, capable of increasing the density of classical seismic recording networks. In this perspective, we adopted micro-electro mechanical system (MEMS) sensors to integrate the use of standard accelerometers for moderate-to-strong seismic events. In addition, we analyse high-rate distributed positioning system data that also record soil motion. In this paper, we present data from the 2016 Central Italy earthquakes as recorded by a spatially dense prototype MEMS array installed in the proximity of the epicentral area, and we compare the results to the signal of local 1s GPS stations. We discuss advantages and limitations of this joint approach, reaching the conclusion that such low-cost sensors and the use of high rate GPS signal could be an effective choice for integrate the spatial density of stations providing strong-motion parameters.

“…This gradual displacement is allowed by the activation of the decoupling fault systems located along the lateral boundaries of Adria (Dinarides and Apennines) and in the northern front of that plate, in the Eastern Southern Alps. The central and southern Dinarides and the Eastern Southern Alps are characterised by thrust faults while a dextral transpressional regime prevails in the northern Tectonic sketch of the Adriatic region (e.g., [10][11][12]). The main wedges in the eastern sector of the Apennine belt are evidenced by colours (inset).…”

The decoupling mechanisms along the western Adria boundary (Apennines) are more complex [10][11][12]16], due to the presence of a shallow crustal structure (eastern sector of the chain, coloured in Figure 2), that is moving independently from Adria and the western (Tyrrhenian) sector of the belt. This tectonic/kinematic context has been determined by the fact that in the most recent evolution (Quaternary) the outer chain, stressed by Adria, has undergone longitudinal shortening, accommodated by major deformations:…”

The recognition of the seismic zones most prone to next major earthquakes in Italy would considerably help the choice of the most efficient prevention plan. This work describes an attempt to gain reliable information about that problem by exploiting the knowledge about the short-term development of the ongoing tectonic processes in the study area and its influence on the spatio-temporal distribution of major shocks. In the periAdriatic zones, such distribution is connected with the progressive northward displacement of the Adria plate, that is controlled by the progressive activation of the decoupling fault systems in the surrounding belts (Dinarides, Apennines and Eastern Southern Alps). The reliability of this hypothesis is evaluated by analysing the seismic histories of the periAdriatic zones. The regularity patterns that are tentatively recognised in such histories are used to identify the most probable location of next major shocks. Further insights into the present seismic hazard in the Southern Apennines and Calabria are tentatively inferred from tectonic connections between these regions and other periAdriatic zones, suggested by the seismic histories in the last 2–4 centuries and the geodynamic/tectonic context in the central Mediterranean area.

“…Finally, the paper by Mantovani et al (2019) is aimed at reviewing the development of the Tyrrenian Sea and the Apennine chain within the Neogene-Quaternary geodynamic framework of the western Mediterranean. The main result is that the whole geodynamic puzzle of the Tyrrhenian area is mainly controlled by the northnorthwestwards motion of Adria, since the Neogene.…”
