Short summary
Our paper concerns the use of a dense network of low-cost seismic accelerometers in populated areas to achieve rapid and reliable estimation of exposure maps in Trentino (northeast Italy). These additional data, in conjunction with the automatic monitoring procedure, allow us to obtain dense measurements which only rely on actual recorded data, avoiding the use of ground motion prediction equations. This leads to a more reliable picture of the actual ground shaking.

This work describes a dataset of 5 years of earthquakes with magnitude range of 2.0–5.5 from January 2019 along the East Anatolian Fault, Türkiye. All events were located using the non-linear location algorithm, providing reliable horizontal locations and depths. The distributed product includes Fourier amplitude spectra, peak ground acceleration and peak ground velocity; we strongly believe that the creation of high-quality open-source datasets is crucial for any seismological investigation.

MUDA (geophysical and geochemical MUltiparametric DAtabase) is a new infrastructure of the National Institute of Geophysics and Volcanology serving geophysical and geochemical multiparametric data. MUDA collects information from different sensors, such as seismometers, accelerometers, hydrogeochemical sensors, meteorological stations and sensors for the flux of carbon dioxide and radon gas, with the aim of making correlations between seismic phenomena and variations in environmental parameters.

Editorial statement
This paper produces a map for all of Italy that classifies different regions in terms of liquefaction triggering potential according to their seismic hazard level. The map MILQ (Mappa del potenziale d’Innesco della LiQuefazione), and the associated data are freely accessible at: www.distav.unige.it/rsni/milq.php. The results can be useful to guide land-use planners in deciding whether liquefaction is a hazard that needs to be considered within the planning processes or not. Furthermore, they can serve as a guide for recommending geological and geotechnical investigations aimed at evaluating liquefaction hazards or, conversely, rule out further studies with a consequent saving in efforts and money.

Short summary
In the present study, we analyze ground-motion hazard maps and hazard disaggregation in order to define areas in Italy where liquefaction triggering due to seismic activity can not be excluded. The final result is a screening map for all of Italy that classifies sites in terms of liquefaction triggering potential according to their seismic hazard level. The map and the associated data are freely accessible at the following web address: www.distav.unige.it/rsni/milq.php.
