Tweed Volcano

From Wikipedia, the free encyclopedia

Tweed Volcano was a prehistoric shield volcano in northeastern New South Wales, Australia. Tweed volcano was formed over the East Australia hotspot when it existed over this part of the continent between 23 million and 20 million years ago. Mount Warning, Tweed Valley and Byron Bay are among the remnants of this volcano that was originally approximately 100 km in diameter and twice the height of Mount Warning today (1156m). Tweed Valley in particular is a large erosion caldera. Despite its great size, Tweed Volcano was not a supervolcano.
