Facts about Erebus

1. 15

   Erebus's summit hosts fumaroles that emit water vapor and carbon dioxide at temperatures exceeding 600 degrees Celsius, creating ice towers through cryogenic processes unique to this Antarctic volcano.

   Continuous volcanic degassing from Erebus creates a localized warm anomaly that prevents ice accumulation in its crater despite temperatures dropping to minus 60 degrees Celsius elsewhere on the Antarctic plateau.

   Erebus's ice towers, which can reach heights of 5-10 meters, form from the interaction of volcanic heat with Antarctic snow and ice, creating unique geological structures found nowhere else on Earth.
