Newer Volcanics Province
Encyclopedia
The Newer Volcanics Province is a complex of volcanic centres formed by the East Australia hotspot
across south-eastern Australia
. It has an area of 6,000 square miles (15,000 square km) with over 400 vents and contains the youngest volcano
es in Australia. The youngest eruptions in the volcanic field
took place at Mount Schank
and Mount Gambier
about 5600 years ago, when explosive activity formed several maar
s and associated lava flows.
Volcanoes within the province include:
East Australia hotspot
The East Australia hotspot is a volcanic hotspot that forces magma up at weak spots in the Indo-Australian Plate to form volcanoes in Eastern Australia. There have been no eruptions in Australia during historic times. It does not produce a single chain of volcanoes like the Hawaiian Islands...

Maar
A maar is a broad, low-relief volcanic crater that is caused by a phreatomagmatic eruption, an explosion caused by groundwater coming into contact with hot lava or magma. A maar characteristically fills with water to form a relatively shallow crater lake. The name comes from the local Moselle...
