Story summary

Italian researchers have developed a method to forecast Mount Etna eruptions using 20 years of earthquake data.
They analyze the b value, which reflects magma movement from the ratio of small to large earthquakes.
The b value can signal internal-stress changes before gas or heat indicators, potentially extending safety lead times.
After the June 2, 2025 eruption, researchers will integrate b value trends with other monitoring tools to improve alerts.
