Its present physical geography and climate have changed over time caused by the movement of tectonic plates and volcanoes but glacial cycles and sea level variation have a more significant effect on the vertebrate communities during the Late Pleistocene. [13] The Late Pleistocene was the time when most animals evolved to resemble modern-day ...
The Late Pleistocene saw the extinction of many mammals weighing more than 40 kilograms (88 lb), including around 80% of mammals over 1 tonne. The proportion of megafauna extinctions is progressively larger the further the human migratory distance from Africa, with the highest extinction rates in Australia, and North and South America.
The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago, during the Late Pleistocene, [2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
The largely submarine Kuwae Caldera cuts the flank of the Late Pleistocene or Holocene Tavani Ruru volcano, the submarine volcano Karua lies near the northern rim of Kuwae Caldera. [2] Bismarck volcanic arc, the Rabaul Caldera includes the sub-vent of Tavurvur and the sub-vent of Vulcan.
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.
In the late Pleistocene, large glaciers extending more than 7.5 miles (12 km) to the east and west carved cirques into the slopes of the volcano. [1] The George Lake and Dry Creek cirques, which face north and northeast, respectively, show evidence of holding glaciers similar to those documented at Canyon Creek cirque on Three Fingered Jack ...
The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
Volcanism that was active in the Pleistocene epoch (1.8 million years ago to approximately 11,700 years ago) of the Quaternary Period during the Cenozoic Era See also the preceding Category:Pliocene volcanism and the succeeding Category:Holocene volcanism
