Calderas usually form as the result of collapse where magmas retreat within an active volcano. News SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. Each of these clans belongs to the greater the Nganduwal dialect tribal group. The shade image was derived by computing topographic slope in the north-south direction.

SRTM was designed to collect 3-D measurements of the Earth's surface. A FORENSIC psychologist has told the murder trial the accused’s cognitive problems... News Tweed volcano The ancient Tweed volcano last erupted 23 million years ago. The dangerous hotspot now slumbers far south of these remnants due to continental drift. In den 20 Millionen Jahren nach dem Ende der Eruptionen fand eine starke Erosion statt, die die Reste der Caldera um den vulkanischen Pfropfen des Mount Warning freilegte und zahlreiche Flüsse wie den Rous- und Oxley River bildete, die in den Tweed River münden.

The first European information about this area is from Captain James Cook‘s journal. Size: 102 kilometers (63 miles) by 74 kilometers (46 miles) Location: 28.4 degrees South latitude, 153.3 degrees East longitude Orientation: North toward the top, cylindrical projection Image Data: Shaded and colored SRTM elevation model Date Acquired: February 2000. Cedar cutters have arrived in the 1840s and established the first permanent settlement in the area in Terranora (originally Taranora meaning little river) in 1843. This has isolated the less erosive central vent of the original volcano, that is now Mt Warning, from the rest of its shield. When stereoscopically merged, the result is a vertically exaggerated view of Earth's surface in its full three dimensions. This asymmetry of erosion has been extreme enough that the volcano has been hollowed out by the east-flowing drainage, forming an "erosional caldera." National Geographic have stated they think it is one of the best preserved erosion calderas in the world. It may be known by a remarkable sharp peaked Mountain lying in land North-West by West from it. Low-relief uplands interspersed between deeply eroded canyons form a radial pattern that clearly defines the shape and extent of the original volcanic dome. [1] Mount Warning, Lamington Plateau und die Border Ranges zwischen New South Wales und Queensland sind die bedeutendsten sichtbaren Relikte dieses Vulkans, der sich ursprünglich über eine Fläche mit einem Durchmesser von 100 km erstreckte.
