    After 36,000 years, a massive volcano near Rome rumbles to life


    July 2016 – ROME, Italy – The country of Italy, home to one of the most famous volcanic disasters in history, is showing signs that another massive eruption is brewing, according to a new study published in the journal Geophysical Research Letters. Almost 2,000 years after the burial of Pompeii and nearby Herculaneum during the eruption of Mt. Vesuvius in 79 A.D., an ancient volcano near Rome is rumbling to life, say scientists. About 19 miles away from the heart of Rome, an ancient volcanic district called the Colli Albani is stirring. The Colli Albani, a 9-mile-long semicircle of hills on the outskirts of Rome, last erupted 36,000 years ago, so geologists had classified it as extinct – until about 20 years ago.

    In the early 1990s, the area around the Colli Albani Volcanic District began showing geological indicators of a future explosion: ground levels shifted, steam vents opened, and earthquakes shook the hills around the site. Since that time, scientists have used these symptoms, along with satellite data and information about the volcano’s previous eruptions, to evaluate the risk that the Colli Albani poses to the surrounding region.....


    The seven hills of Rome, a Geological Tour of the Eternal City - Heiken, Funiciello & Di Rita 2007


    ....The chapters are arranged geographically and cover each of the seven hills, the Tiber floodplain, ancient creeks that dissected the plateau and ridges that rise above the right bank....

    The seven hills are actually eroded remnants of a volcanic plateau dissected over many centuries by streams. The origin of these deposits are the Volcano of the Colli Albani to the SE and the Sabatini volcanic complex to the NW of the city.
