The Ontong Java Plateau forms from 125 to 120 million years ago; Paraná and Etendeka traps, Brazil, Namibia and Angola form 128 to 138 million years ago. 132 million years ago, a possible supervolcanic eruption occurred, ejecting 8,600 cubic kilometers (2,063 cu mi). [90] Formation of the Karoo-Ferrar flood basalts begins 183 million years ago.
The Hekla 3 eruption (H-3) c. 1000 BC is considered the most severe eruption of Hekla during the Holocene. [2] It threw about 7.3 km 3 of volcanic rock into the atmosphere, placing its Volcanic Explosivity Index (VEI) at 5. This would have caused a volcanic winter, cooling temperatures in the Northern Hemisphere for several years afterwards.
Chaos Crags is the youngest group of lava domes in Lassen Volcanic National Park, California.They formed as six dacite domes 1,100-1,000 years ago, one dome collapsing during an explosive eruption about 70 years later.
The impact generated winds in excess of 1,000 kilometers per hour (620 mph) near the blast's center, [32] and produced a transient cavity 100 kilometers (62 mi) wide and 30 kilometers (19 mi) deep that later collapsed. This formed a crater mainly under the sea and currently covered by ~1,000 meters (3,300 ft) of sediment.
But the debris that covered the town also preserved it until the remains were rediscovered some 1,700 years later. This beautiful statue is one of more than 150 priceless artifacts displayed at ...
Satellite images of the 15 January 2022 eruption of Hunga Tonga-Hunga Haʻapai. This is a list of volcanoes that have had large explosive eruptions during the Holocene (since about 11,650 years Before Present), with a volcanic explosivity index (VEI) of 5 or higher, or a plume height of at least 30 km.
The mighty baobab has grown across mainland Africa, Madagascar and Australia for millions of years. But until now, scientists disputed where they came from. Finally, an answer to a mystery ...
