The East Australia hotspot is marked 30 on map.

The East Australia hotspot is a volcanic hotspot that takes advantage of weak spots in the Indo-Australian Plate to feed magma to the volcanoes of Eastern Australia. A volcanic crater is a circular depression in the ground caused by volcanic activity Mount Schank is a dormant Maar Volcano in the south-east of South Australia, near Mount Gambier. In Geology, a hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time The Indo-Australian Plate is a major Tectonic plate that includes the continent of Australia and surrounding Ocean, and extends northwest to include the Magma (Plurals magmas and magmata) is molten rock that sometimes forms beneath the surface of the Earth (or any other Terrestrial planet Plate tectonics and hotspots Divergent plate boundaries At the The Eastern states of Australia refers to the states adjoining the east coast of Australia. It does not produce a single chain of volcanoes like the Hawaiian Islands. The Hawaiian Islands, once known as the Sandwich Islands, form an Archipelago of 19 Islands and Atolls numerous smaller Tweed Volcano in New South Wales is a large shield volcano that was formed by the hotspot about 23 million years ago and has one of the biggest erosion calderas in the world. Tweed Volcano was an early Miocene Shield volcano in northeastern New South Wales, Australia. A shield volcano is a large Volcano with shallow-sloping sides A caldera is a cauldron-like volcanic feature formed by the collapse of land following a volcanic eruption The most recent eruptions were about 5,000 years ago and formed the volcanoes Mount Schank, Mount Gambier and Mount Napier in the Newer Volcanics Province. Mount Schank is a dormant Maar Volcano in the south-east of South Australia, near Mount Gambier. Mount Napier in Victoria, Australia, one of the youngest Volcanoes in Australia last erupted about 5290 BC The Newer Volcanics Province is a complex of volcanic centers formed by the East Australia hotspot across south-eastern Australia.

Unlike most hotspots, the East Australia hotspot has explosive eruptions, unlike the runny lava flows of the Hawaii hotspot, the Iceland hotspot and the Réunion hotspot. Lava is molten rock expelled by a Volcano during an eruption When first expelled from a volcanic vent it is a Liquid at Temperatures The Hawaiian Islands, once known as the Sandwich Islands, form an Archipelago of 19 Islands and Atolls numerous smaller The Iceland hotspot is a hotspot which is partly responsible for the high volcanic activity which has formed the island of Iceland. The Réunion hotspot is a Volcanic hotspot which currently lies under the Island of Réunion in the Indian Ocean. The hotspot is explosive because basaltic magma is trapped in the less dense continental crust, which is heated and melts to form rhyolites. Basalt (bəˈsɔːlt ˈbeisɔːlt ˈbæsɔːlt is a common Extrusive Volcanic rock. Magma (Plurals magmas and magmata) is molten rock that sometimes forms beneath the surface of the Earth (or any other Terrestrial planet This page is about a volcanic rock For the ghost town see Rhyolite Nevada, and for the satellite system see Rhyolite/Aquacade. These rhyolites can be quite hot and form violent eruptions, despite their low water content.
