About Melbourne
Melbourne is a stratovolcano rising to 2,732 meters (8,964 feet) in Antarctica's Antarctic-Scotia Volcanic Regions. Its last known eruption was in 1892 CE. The volcano has produced 1 recorded eruption.
Geography & Climate
Melbourne is located in Antarctica, within the McMurdo Volcanic Province of the broader Antarctic-Scotia Volcanic Regions. Situated at 74.35° S, 164.70° E in the Southern Hemisphere, the volcano lies within a polar climate zone. At 2,732 meters above sea level, Melbourne rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Melbourne is an intraplate volcano, meaning it formed away from any plate boundary. These volcanoes are often powered by hotspots — plumes of abnormally hot mantle material rising from deep within the Earth. Hotspot volcanoes like Melbourne tend to produce effusive eruptions with lava flows that can be relatively predictable, giving nearby communities in Antarctica more time to prepare. However, they can also produce explosive phases, particularly when magma interacts with groundwater. The dominant rock type is trachyte / trachydacite, an intermediate to silica-rich volcanic rock. This composition typically produces more viscous magma, leading to more explosive eruptions with ash columns and pyroclastic flows. Andesitic and dacitic magmas build pressure before erupting, which is why volcanoes with this rock chemistry are often associated with Plinian-style eruptions that can send ash tens of kilometers into the atmosphere and disrupt aviation across entire regions.
Eruption History Summary
Melbourne has 1 recorded eruption in the geological database, spanning from 1892 CE to 1892 CE.
GVP Reference Summary
Mount Melbourne is a large undissected stratovolcano along the western coast of the Ross Sea in Antarctica's northern Victoria Land. The glacier-covered edifice lies at the center of a volcanic field containing both subglacial and subaerial vents along a dominantly N-S trend. A large number of scoria cones, lava domes, viscous lava flows, and lava fields are exposed at the summit and upper flanks. A number of very young-looking cones are located at the summit and on the flanks. Tephra layers are found within and on top of ice layers, and the most recent eruption was estimated to have occurred between 1862 and 1922. The volcano displays fumarolic activity that is concentrated along a NNE-SSW line cutting through the summit area and along a line of phreatomagmatic craters on the southern rim of the summit crater. Prominent ice towers and pinnacles were formed from steam condensation around fumarolic vents.

Frequently Asked Questions About Melbourne
Is Melbourne an active volcano?+
Melbourne is not currently classified as active. Its activity evidence is listed as "Eruption Dated." The last known eruption was in 1892 CE. However, no volcano is ever considered permanently extinct.
When did Melbourne last erupt?+
The most recent recorded eruption of Melbourne occurred in 1892 CE. The eruption was classified as a "Confirmed Eruption." Melbourne has 1 recorded eruption in total.
How high is Melbourne?+
Melbourne has a summit elevation of 2,732 meters (8,964 feet) above sea level. At 2,732 meters, it is comparable in height to many significant mountain peaks and stands well above the tree line.
What type of volcano is Melbourne?+
Melbourne is classified as a Stratovolcano. Stratovolcanoes (also called composite volcanoes) are steep, conical volcanoes built up by many layers of hardened lava, tephra, and volcanic ash. They are among the most common and dangerous types, known for explosive eruptions.
Where is Melbourne located?+
Melbourne is located in Antarctica, in the Antarctic-Scotia Volcanic Regions. More specifically, it lies within the McMurdo Volcanic Province. Its exact coordinates are -74.350° latitude, 164.700° longitude.
Is it safe to visit Melbourne?+
Melbourne can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. Antarctica may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
