Estimating the Magnitude of Historical Earthquakes from Macroseismic Intensity Data: New Relationships for the Volcanic Region of Mount Etna (Italy)

Scientists have developed new relationships to estimate the magnitude of historical earthquakes using macroseismic intensity data, specifically for the volcanic region of Mount Etna, Italy. This breakthrough enhances our understanding of past seismic activity in one of Europe's most active volcanic areas. The study leverages a rich dataset of historical records dating back to the late 1600s, comparable in scope to that of Vesuvius. Researchers analyzed macroseismic data from 1832 to 1998, refining existing methodologies to improve accuracy and reliability. These findings provide valuable insights for seismic hazard assessment and risk management in volcanic regions.
