[2] The ice volcano or cryovolcano Doom Mons forms a roughly circular mountain measuring about 65 kilometres (40 mi) across.

A subsequent flyby by Cassini re-surveyed the region from a different angle, enabling members of the US Geological Survey Astrogeology Science Center to generate stereoscopic mapping of Sotra Patera and the surrounding area.

[4] With Doom Mons, Sotra Patera is regarded as "the very best evidence, by far, for volcanic topography anywhere documented on an icy satellite", according to planetary scientist Jeffrey Kargel of the University of Arizona.

[3] It is unclear what might have been erupted from Sotra Patera—possibly water mixed with ammonium, or more exotic hydrocarbon compounds such as polyethylene, paraffin waxes or asphalt.

[5] The eruptions of Sotra Patera are presumed to originate in a layer of liquid water lying below Titan's icy crust.
