Simon Winchester; Krakatoa: The Day the World Exploded, 27 August 1883 [10] explores the eruption of Krakatoa and the history of the region, the early spice trade, the growth of colonial governments, explains the geology of volcanos and describes in detail the series of eruptions and tsunamis and their effects around the globe.
The video shows August footage from Mount Dukono, an active volcano in Indonesia, not Yellowstone National Park. No evidence supports the post’s claim of a Yellowstone volcanic eruption in ...
An eruption column or eruption plume is a cloud of super-heated ash and tephra suspended in gases emitted during an explosive volcanic eruption. The volcanic materials form a vertical column or plume that may rise many kilometers into the air above the vent of the volcano. In the most explosive eruptions, the eruption column may rise over 40 km ...
A volcanic eruption is essentially the only natural way for short-lived – less than a few years – gases like sulfur dioxide and water vapor to make it into the stratosphere.
A tuya is a flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet. They are rare worldwide, being confined to regions which were covered by glaciers and had active volcanism during the same period. As lava that erupts under a glacier cools very quickly and cannot travel far, it piles up into a steep-sided ...
A volcanic eruption in Italy sent people fleeing Wednesday, with many forced to escape the fiery explosion by boat. The Stromboli volcano, located on the island of Stromboli, near Sicily, began ...
An eruption on 16 March injured 10 people, including a BBC News television crew, after magma exploded upon contact with snow. [97] [98] 3 Mount Ontake [99] Japan 2014 63 A phreatic eruption and pyroclastic flow occurred without warning, killing 63 people. Deadliest eruption in Japan since 1902, first volcano-related deaths in Japan since 1991. 2
If the magma is not vented to the surface in a volcanic eruption, it will slowly cool and crystallize at depth to form an intrusive igneous body, one, for example, composed of granite or gabbro (see also pluton). Often, a volcano may have a deep magma chamber many kilometers down, which supplies a shallower chamber near the summit.
