Background
The Colli Albani caldera was formed during an eruptive period with six major explosive eruptions producing at least 280 cu km of ejecta between about 560,000 and 350,000 years ago. Subsequent eruptions occurred from a new 5-km-wide central cone and from many phreatomagmatic craters and cones within the Artemisio-Tuscolana caldera and on its outer flanks. The post-caldera eruptions have buried the western side of the caldera rim.The largest of the post-caldera craters is Lake Albano, a 4 x 2.5 km wide maar constructed at the WSW margin of the caldera in 5 stages dating back to about 45,000 years ago. Eruptive products of the 3rd stage were dated at 26,000 yrs Before Present (BP). The 4th and 5th stages were not dated directly, but sediment-core gaps at 16,000 and 7500 yrs BP may correspond to these eruptions (Villa et al., 1999). Reported historical eruptions during the Roman period are uncertain, but seismic swarms of up to two years duration have been recorded since Roman times.

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
