A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. [1] If the magma finds a path to the surface, then the result will be a volcanic eruption ...
The magma that would normally fill the chamber and become sealed is believed to have drained away, to the bewilderment of scientists, revealing the rift beneath the surface. [4] In August 2015, the members of the Icelandic band Kaleo and fourteen support staff descended into the volcano's magma chamber and recorded a live rendition of the band ...
"Cities in Dust" is a dance-rock, [1] and dance-pop song. [2] The lyrics describe the city of Pompeii, destroyed in a volcanic eruption in 79 AD.Imagery describing the volcano and its magma chamber, the condition of the victims of the eruption, and the subsequent discovery and excavation of the city comprises the bulk of the lyrics.
2850 BC [4] Climbing. Easiest route. Drive. Mount Mazama (Tum-sum-ne in the Native American language Klamath [5]) is a complex volcano in the western U.S. state of Oregon, in a segment of the Cascade Volcanic Arc and Cascade Range. The volcano is in Klamath County, in the southern Cascades, 60 miles (97 km) north of the Oregon– California ...
Magma that cools slowly within a magma chamber usually ends up forming bodies of plutonic rocks such as gabbro, diorite and granite, depending upon the composition of the magma. Alternatively, if the magma is erupted it forms volcanic rocks such as basalt , andesite and rhyolite (the extrusive equivalents of gabbro, diorite and granite ...
A crystal mush is magma that contains a significant amount of crystals (up to 50% of the volume) suspended in the liquid phase (melt). [1] As the crystal fraction makes up less than half of the volume, there is no rigid large-scale three-dimensional network as in solids. [2] As such, their rheological behavior mirrors that of absolute liquids.
Plinian eruption. Plinian eruption: 1: ash plume; 2: magma conduit; 3: volcanic ash fall; 4: layers of lava and ash; 5: stratum; 6: magma chamber. 1822 artist's impression of the eruption of Mount Vesuvius in 79, depicting what the AD 79 eruption may have looked like, by the English geologist George Julius Poulett Scrope.
The Soufrière Hills is an active, complex stratovolcano with many lava domes forming its summit on the Caribbean island of Montserrat. After a long period of dormancy, the Soufrière Hills volcano became active in 1995 and continued to erupt through 2010. [3] Its last eruption was in 2013. [2] Its eruptions have rendered more than half of ...
