Italian scientists have warned that a long-dormant volcanic complex in Colli Albani, a set of hills about 20km from Rome, is still active and “waking up.”.

Experts and scientists at the National Italian Institute of Geology and Volcanology in Rome say the volcano has the potential to erupt as violently as Mount Vesuvius did in 79 AD when it destroyed nearby Pompeii. The discovery was made during research into historic eruption patterns of the Colli Albani volcanic complex, which last erupted 36,000 years ago.
Scientists also discovered that the ongoing pressure of gas and magma underground is causing the hills to rise by 2 millimeters each year.
