Residents on 'Edge' Facing 2.5K Earthquakes as Italian Supervolcano Rumbles

"Italy’s government has been preparing for a possible mass evacuation of tens of thousands of residents due to a supervolcano that has caused 2,500 earthquakes since September, several media outlets reported.

Residents in the city of Pozzuoli, which is outside of Naples, are concerned about the recent activity since they live in the volcanic area of Campi Flegrei ....“It’s nonstop earthquakes here,” said Luca Averna....a supervolcano is defined as “a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time, it erupted more than 240 cubic miles of material.” Relatedly, a “supereruption” is a term that describes VEI 8 eruptions. A phenomenon known as bradyseism has been attributed to the increase of recent earthquakes in the Campi Flegrei area, The Wall Street Journal reported.
Christopher Kilburn, a professor of volcanology and geophysical hazards at University College London, told NBC News that he thinks that the activity at Campi Flegrei is due to a change in the structure of the volcano’s crust." MS
