Mount Doom

Mount Doom, also named Amon Amarth (meaning Mount Doom) and Orodruin (meaning Fiery Mountain), is an active stratovolcano in Mordor, Middle Earth. It is 2286 meters tall.

It is not a powerful volcano, but is extremely active. It’s eruptions are hybrid Strombolian and mainly Hawaiian (effusive) type and pyroclastic flows are rare, while lava fountains are rather common. Because of the constant spewing of ash and toxic volcanic gasses, all surrounding area is unhospitable.

The volcano is seen as sentient and is considered an evil presence.

Morphology
Due to the high frequency of effusive eruption, slopes of Mt. Doom are rather gentle, but not enough to be classified as shield volcano. It has the typical concave flanks of a stratovolcano and near the summit, slopes are steep (about 30°). Mount Doom has a persistent lava lake on the bottom of it's crater.
