Gehennum is situated over an active subduction zone (there is a pelagic trench to the north), and sports scores of dormant and semi-active volcanoes, including [[[Mount Parnas]] (which is reputedly the tallest mountain on the World of Isles), Mount Samars, and Mount Taygetus.

Volcanoes are generally induced not to explode by sacrifices offered to their daimon. Human sacrifice for this purpose is still common enough in the Archaic Period, but is outlawed in the Classical Period, and is a little-heard-of outrage in the Decadent Period.
