![]() ![]() At least one lava lake has churned within its caldera since 1972. It regularly emits plumes of gas and steam, and occasionally spits out rock (bombs) in strombolian eruptions. What is the Mount Erebus team researching in Antarctica?Īn international collaboration of scientists is using electromagnetic emissions from lightning strikes and solar wind to map the inner workings of Antarctica’s Mount Erebus, the world’s southernmost active volcano. The summit contains a persistent convecting phonolitic lava lake, one of five long-lasting lava lakes on Earth. Geology and volcanology Mount Erebus is currently the most active volcano in Antarctica and is the current eruptive zone of the Erebus hotspot. What is the geological area of Mount Erebus? To the south, the Erebus ice tongue stretches out into McMurdo Sound. ![]() The Mount Erebus stratovolcano rises 3794 meters (12,447 feet) above sea level. The stratovolcano, which frequently has active lava lakes in its 250-m wide summit crater, is primarily monitored by satellite. What type of volcano is Mt Erebus?Įrebus, located on Ross Island, Antarctica, and overlooking the McMurdo research station, is the southernmost active volcano in the world. The summit of this volcano collapsed at some time during the next 350,000 years, resulting in the formation of Fang Ridge. The existing model shows that a cone formed on a shield volcano (volcano with sloping sides) between 1.3 and 0.7 million years ago. This area is a rift zone where extension takes place and has thinned the crust to 20 km and allows magma to rise.Įrebus. Erebus volcano is an intraplate volcano and belongs to the McMurdo Volcanic Group, located in the so-called Terror Rift, which is part of the West Antarctic Rift System. What type of geologic feature is causing Mount Erebus? About 95% of the edge of the plate is a divergent (spreading) plate boundary. ![]() The Antarctica plate is mostly asesmic and moves little relative to other plates. 5 What kind of volcano is Mount Erebus in New Zealand?.4 Is Mount Erebus a cinder cone volcano?.3 What is the Mount Erebus team researching in Antarctica?.1 Which tectonic plate is Mount Erebus?. ![]()
