Response of Mount Etna to dynamic stresses from distant earthquakes

Distant earthquakes can significantly alter volcanic activity through dynamic stress transfer, as demonstrated by Mount Etna's response to seismic events. Research shows that the 2006 Greece earthquake (M=6.8) triggered changes in tremor patterns and a swarm of volcano-tectonic earthquakes, likely due to permeability variations and magmatic fluid activation. Similarly, the 2008 Sichuan earthquake (M=7.9) modified seismo-volcanic signals and provoked an eruption by inducing bubble nucleation in volatile-rich magma, increasing pressure and long-period events. The study analyzed seismic signals during these periods, revealing that dynamic stresses can modify a volcano's state, with implications for volcanic hazard assessment.
