How old are the undara lava tubes?
approximately 190,000 years ago
The volcanic activity that formed the tubes occurred approximately 190,000 years ago and the Undara volcano expelled massive amounts of lava onto the surrounding Atherton Tableland, covering about 1550 square kilometres. In total it was estimated that over 23 billion cubic metres of lava was released.
When was undara lava tubes formed?
about 190,000 years ago
The Undara Lava Tubes were created about 190,000 years ago when a staggering 23 cubic kilometres of lava flowed into a river bed and kept flowing for 160km, making it the world’s longest lava flow from a single volcano. Huge caves, some over 21m wide and up to 10m high, have formed in places along the tubes.
Where are the undara caves?
Tundra form in two distinct cold and dry regions. Arctic tundra are found on high-latitude landmasses, above the Arctic Circle—in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, for example—or on far southern regions, like Antarctica.
Who owns Undara Lava Tubes?
The G’Day Group
The G’Day Group, which operates a host of Australian tourism experiences including El Questro in WA, Kings Canyon in the NT, and the Discovery – Rottnest Island glamping experience among others, is the new owner of the Undara Experience. nearly 160 years ago, who still graze cattle in the area six generations later.
How was Undara formed?
The Undara Lava Tubes were formed when 23 cubic kilometres of lava from one of the many volcanoes spilled out over the land and travelled along a river bed. The tubes were formed when the outer layer formed a crust which protected the still-molten lava which continued to flow as though it was in a tube or a pipe.
How did Undara Lava Tubes form?
The lava tubes and caves were formed when rivers of lava confined to a valley crusted over and formed a roof. Insulated in its casing of solidified lava, the lava flow carried on for tens of kilometres before draining out, leaving an empty tube of lava.
What caused the Undara Lava Tubes?
About 190,000 years ago, a large volcano erupted violently, spewing molten lava over the surrounding landscape. The lava flowed rapidly down a dry riverbed. The top, outer-layer cooled and formed a crust, while the molten lava below drained outwards, leaving behind a series of hollow tubes.
Where are the Undara Lava Tubes?
Location. The Undara Lava Tubes are located 264 km south-west of Cairns, 485 km from Townsville and 1,738 km north-west of Brisbane via Roma on the Warrego and Carnarvon Highways.
