The Alban Hills (Colli Albano) complex immediately SE of Rome contains a large Pleistocene stratovolcano with a 10 x 12 km wide caldera. The 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 compound maar constructed at the WSW margin of the caldera in multiple stages dating back to about 69,000 years ago. The age of the most recent eruptions from the Albano maar is not known precisely; variable dates range from about 36,000 years ago to perhaps the Holocene, when several perhaps non-volcanic lake overflow lahars occurred. Reported historical eruptions during the Roman period are uncertain, but seismic swarms of up to two years duration have been recorded since Roman times.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Lake-filled Albano maar is part of the Alban Hills (Monte Albano) complex immediately SE of Rome. The Cavo scoria cone rises beyond the far rim. The Monte Albano complex contains a large Pleistocene stratovolcano with a 10-km-wide caldera. Subsequent eruptions occurred from a new 5-km-wide central cone and from many phreatomagmatic craters and cones within the caldera and on its outer flanks. The youngest dated magmatic eruption occurred during the late-Pleistocene, but the possibility of Holocene phreatic eruptions has not been excluded.
