Focal mechanisms of the Southeastern Alps and surroundings

Saraò Angela; Sugan Monica; Bressan Gianni; Renner Gianfranco; Restivo Andrea

This is a focal mechanism dataset of 772 earthquakes that occurred in the southeastern Alps and surrounding areas ( latitude 45°N-47.5°N and longitude 10°E-15°E) from 1928 to 2019 with 1.8 ≤ M ≤ 6.5.  To provide a comprehensive set of revised information, we collected and revised the focal mechanisms previously published in the literature (883 focal mechanism solutions). Furthermore, depending on the data quality and availability, we computed new focal mechanisms by first arrival polarity inversion (for 108 events) or seismic moment tensor (for 46 events). For each earthquake, we report all the available focal mechanisms and suggest a preferred solution for users who need expeditious information.

The methodologies and data used to obtain the dataset and to outline its main characteristics are described in
