This dataset includes focal mechanisms (FPFIT_solution.pdf, FPFIT_solution.csv) obtained with the FPFIT algorithm (Reasenberger and Oppenheimer, 1985) for 162 earthquakes with magnitudes Md between 2.8 and 3.6 that occurred between 2014 and 2023 in the Southeastern Alps region (45°N-47.5°N and 10°E-15°E). This dataset updates the catalogues Saraò et al., 2021a, b, and Sugan et al., 2020. The first polarities used to calculate the focal mechanisms are manually picked from seismograms recorded by the National Institute of Oceanography and Applied Geophysics (OGS) northeastern Italy seismic and deformation network (Sistema di Monitoraggio terrestre dell’Italia Nord Orientale - SMINO) (Priolo et al., 2005; Bragato et al., 2011; Bragato et al., 2021) and various Italian and European seismological observatories using temporary and permanent seismic networks. The permanent and temporary networks are as follows: CH – Swiss Seismological Service, 1983; GU – University of Genoa, 1967; IV – INGV Seismological Data Centre, 2005; MN – MedNet Project Partner Institutions, 1990; NI – OGS and University of Trieste, 2002; OE – ZAMG, 1987, 1990; OX – OGS, 2016; RF – University of Trieste, 1993; SI - Sudtirol Network, Italy (https://www.fdsn.org/networks/detail/S.I/; SL – Slovenian Environment Agency, 1990; ST – Geological Survey – Provincia Autonoma Di Trento, 1981; XT – Zhao et al, 2018; Y5 – Swiss Seismological Service, 2022; Z3 – AASN, 2015; ZO - Massa et al, 2021; ZS - Heit et al., 2017.

Abstract
This dataset includes focal mechanisms (FPFIT_solution.pdf, FPFIT_solution.csv) obtained with the FPFIT algorithm (Reasenberger and Oppenheimer, 1985) for 162 earthquakes with magnitudes Md between 2.8 and 3.6 that occurred between 2014 and 2023 in the Southeastern Alps region (45°N-47.5°N and 10°E-15°E). This dataset updates the catalogues Saraò et al., 2021a, b, and Sugan et al., 2020. The first polarities used to calculate the focal mechanisms are manually picked from seismograms recorded by the National Institute of Oceanography and Applied Geophysics (OGS) northeastern Italy seismic and deformation network (Sistema di Monitoraggio terrestre dell’Italia Nord Orientale - SMINO) (Priolo et al., 2005; Bragato et al., 2011; Bragato et al., 2021) and various Italian and European seismological observatories using temporary and permanent seismic networks. The permanent and temporary networks are as follows: CH – Swiss Seismological Service, 1983; GU – University of Genoa, 1967; IV – INGV Seismological Data Centre, 2005; MN – MedNet Project Partner Institutions, 1990; NI – OGS and University of Trieste, 2002; OE – ZAMG, 1987, 1990; OX – OGS, 2016; RF – University of Trieste, 1993; SI - Sudtirol Network, Italy (https://www.fdsn.org/networks/detail/S.I/; SL – Slovenian Environment Agency, 1990; ST – Geological Survey – Provincia Autonoma Di Trento, 1981; XT – Zhao et al, 2018; Y5 – Swiss Seismological Service, 2022; Z3 – AASN, 2015; ZO - Massa et al, 2021; ZS - Heit et al., 2017.
