Mt Erebus is an active volcano with a lava crater which periodically has mild eruptions; the volcano has a distinctive petrology with kenyite, an olivine bearing |
phonolite with large phenocrysts; thermally heated ground is common on the upper slopes and possibly provides a habitat for some soil biological species |
