Effusive eruption of basaltic ʻaʻā lava at Mauna Loa in 1984. There are two major groupings of eruptions: effusive and explosive. [1] Effusive eruption differs from explosive eruption, wherein magma is violently fragmented and rapidly expelled from a volcano.
A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling ...
In volcanology, a pressure ridge or a tumulus (plural: tumuli), and rarely referred to as a schollendome, is sometimes created in an active lava flow. [1] Formation occurs when the outer edges and surfaces of the lava flow begin to harden. [1] If the advancing lava underneath becomes restricted it may push up on the hardened crust, tilting it ...
When a sub-aerial lava flow reaches the ocean (or other large body of water), contact with the water causes both rapid cooling of the lava and steam explosions that fragment it. The glassy fragments that are formed, known as hyaloclastites, fall down to the seabed forming foresets. As the seabed topography becomes infilled, the subaerial flow ...
La'uf al HaMillion (Hebrew: לעוף על המיליון) is an Israeli game show hosted by Yaron Brovinsky. It has been broadcast on Channel 10 since December 2010. The show's format was specially developed for Channel 10 by July August Productions.
A block and ash flow or block-and-ash flow is a flowing mixture of volcanic ash and large (>26 cm) angular blocks [1] commonly formed as a result of a gravitational collapse of a lava dome or lava flow. [2] Block and ash flows are a type of pyroclastic flow and as such they form during volcanic eruptions. [3]
In computer programming jargon, lava flow is an anti-pattern that occurs when computer source code written under sub-optimal conditions is deployed into a production environment and subsequently expanded upon while still in a developmental state. The term derives from the natural occurrence of lava which, once cooled, solidifies into rock that ...
Lava Cast Forest is a visitor destination within the Newberry National Volcanic Monument near Bend, in the U.S. state of Oregon.It is a geologic feature containing a 6,000 year old lava flow that created lava molds of ancient trees. [1]
