Mount Erebus: terrain elevation and local relief
Mount Erebus uses an approximately 3,788-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 2,185 meters of local relief above its lowest sampled point. Published summit surveys are separate references.

A little more perspective
The Smithsonian Global Volcanism Program lists Erebus at 3,794 meters. This Copernicus surface reaches approximately 3,788 meters in EGM2008, about 86 meters from the profile coordinate. The selected section omits much of Ross Island and does not model the volcano’s rise from the surrounding sea. Neutral shading represents the dated surface without adding a plume, exposed lava or a claim about current snow cover.
The local-relief view subtracts the lowest sampled point in this section: 1603.1 meters at -77.560833° latitude, 166.941667° longitude. This produces about 2,185 meters of relief within the stated boundary. It is not a universal mountain base, a route’s total ascent, or topographic prominence.
The rendered surface uses the public 2021 Copernicus release, primarily based on TanDEM-X observations from 2011–2015 with infill from other sources. It is a surface model rather than a current bare-earth survey. Neutral shading explains the geometry without claiming a snow season or photographic ground texture. No datum conversion or summit correction is applied.
Quick facts
Mount Erebus uses an approximately 3,788-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 2,185 meters of local relief above its lowest sampled point. Published summit surveys are separate references.
