A Comprehensive Moment Magnitude Catalog for the Northeastern Italy Region

We present a comprehensive catalog of independent moment magnitude (Mw) estimates for northeastern Italy and its neighboring regions using data from the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OX) network. The catalog, spanning from 2016 to 2023, covers the geographical area between 10.0°–14.5° north latitude and 44.5°–47.0° east longitude. In this region, we identified 11,685 low-to-moderate magnitude earthquakes (−0:70 ≤ ML ≤ 4:35) suitable for independent Mw computation. To enhance accuracy, we incorporated new homogeneous estimates of local magnitude (ML). A newly developed routine enables rapid near-real-time Mw estimation and permits regular, rolling seismic catalog updates. We also established an empirical relationship between Mw and ML specific to our study region. Our study provides a detailed and accurate Mw catalog of independent estimates that significantly improves critical applications such as seismic hazard assessment, and risk mitigation in this ...
