A new study is warning that a volcano may be awakening in Italy in the Colli Albani Volcanic District, on the outskirts of Rome. A new
Geophysical Research Letters study, authored by Fabrizio Marra and others,
reports that over four million people could be at risk if the Colli Albani volcano complex, bordering the Rome metropolitan area, goes into a full-scale eruption.
The Alban Hills, or
Colli Albani as it is called locally, was particularly active between 608,000-351,000 years ago, when it produced massive eruptions of ash totaling some 67 cubic miles, Wired reported.
"This change in behavior is good news for Rome, because the
Colli Albani appears to be more regular in the spacing of its eruptions than most volcanoes. In their new study, Marra and team identify dormancy and recurrence intervals for the
Colli Albani that, since 608,000 years ago, have varied from 29,000±2,000 to 57,000±4,000 years, averaging 41,000±2,000 years between eruptions and 38,000±2,000 years between periods of renewed activity," Wired detailed.
Researchers propose that, as it has been roughly 36,000 years since the most recent eruptions, and that the volcanos have been remarkably consistent in their patterns, they may be due for a period of increased activity. The revelations are troubling, as the area is a mere 16 miles from the center of Rome.
"Rome doesn't have to harbor the same apprehension that Naples must have for the Campi Flegrei and Vesuvius.
However, this would be an excellent time to start planning, in case the Colli Albanidoes decide it is time to wake back up," Wired suggested.
