Forty kilometers north of Pretoria lies a ring of hills a kilometer in diameter and 100 meters high. These hills are the walls of an impact crater left by an asteroid which hit there some 200 000 years ago. The Tswaing crater is similar in size to the well-known Barringer meteor crater in Arizona. The crater walls at Tswaing were originally about twice as high as they are today.
This aerial view looks west over the 250-meter-deep circular lake that fills the New Quebec Crater, a relatively large, well-preserved crater. The interior topography of the crater is covered by lake sediments that inhibit a determination of whether the structure has a small central uplift. The rocks involved in this impact event are ancient and strongly deformed gneisses of the Precambrian shi...
This is NOT a crater. It does not match any terrain that surrounds it, and the highlights of the light are opposed to those found in the surrounding craters which means this in rising into the air and not sinking into the ground. There are no Hard edges to define this shape as solid as the craters around it and it is visible from very far away. You may not care for the 4 lights found close b...
This crater is located inside Virunga National Park, in the Democratic Republic of the Congo. The main crater is about two km (6,562 ft.) wide and usually contains a lava lake. The crater presently has two distinct cooled lava benches within the crater walls - one at about 3175m (10,400 ft) and a lower one at about 2975m (9,800 ft).
The Silverpit crater in the North Sea was discovered in 2002 during a seismic oil exploration .
The crater is about 2.4 km wide and surrounded by a set of concentric rings, which extend to about 10 km away from its centre.
Its age is thought to be about 65 million years old, roughly coincident with the formation of the Chicxulub Crater.
The crater currently lies below a ...
