“According to LiveScience, Campi Flegrei is often referred to as a “supervolcano,” which can produce eruptions reaching a category 8 — the highest level on the Volcano Explosivity Index. However, Campi Flegrei’s biggest-ever eruption technically ranked as a category 7, which is still considered a very large and disastrous eruption, LiveScience reported.”

Ah, nothing to worry about.
