Summary

Story summary

Italy's National Institute of Geophysics and Volcanology (INGV) developed a method to predict Mount Etna eruptions by monitoring the b value.
The b value tracks magma movement and crustal stress changes, signaling eruptions.
The method can warn months in advance by detecting b value variations before geochemical anomalies.
About 1 million people live near Etna, underscoring the need for timely predictions given its 2,700-year eruptive history.
