The gas released at the surface has a composition that is a mass-flow average of the magma exsolved at various depths and is not representative of the magma conditions at any one depth. Molten rock (either magma or lava) near the atmosphere releases high-temperature volcanic gas (>400 °C).
The word lava comes from Italian and is probably derived from the Latin word labes, which means a fall or slide. [2] [3] An early use of the word in connection with extrusion of magma from below the surface is found in a short account of the 1737 eruption of Vesuvius, written by Francesco Serao, who described "a flow of fiery lava" as an analogy to the flow of water and mud down the flanks of ...
Flow bands are present in massive, uniform felsic lava flow units. [36] When the viscous lava flow encounters a surface, friction drags the mobile lava and forms internal banding. [36] Structureless hyaloclastite is commonly found in Archean felsic volcanic rocks. [7] [17] [36] [37] In submarine environments, water quenches and cools lava ...

The stream of molten rock from the Cumbre Vieja volcano, which began erupting in mid-September, reached the water near the popular surf spot of Los Guirres beach just before 2 a.m, according to ...
Also composed of rhyodacite lava, it originated from a vent on the northern side of the complex eastward of Llao Rock. It likely only occurred weeks or months before the major eruption, as Mazama's collapse formed a backward flow of lava when it cut through the Cleetwood lava, suggesting that the Cleetwood lava was still hot enough to flow and ...
