Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified (sometimes referred to as frozen lava lakes).
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 ...
The depth of the lava lake varies considerably. A maximum elevation of the lava lake was recorded at about 3,250 m (10,660 ft) prior to the January 1977 eruption – a lake depth of about 600 m (2,000 ft). Following the January 2002 eruption, the lava lake was recorded at a low of about 2,600 m (8,500 ft), or 900 m (3,000 ft) below the rim. [2 ...
Lava Lakes. The Lava Lakes are a group of small lakes at the head of Lava Fork in the Boundary Ranges of northwestern British Columbia, Canada. [1] The Volcano, a cinder cone about 5 km (3.1 mi) north of the British Columbia-Alaska border above the eastern shore of the Lava Lakes, is the source for lava flows that overwhelm the lakes. [2]
Erta Ale is 613 metres (2,011 ft) high, with one or sometimes two active lava lakes at the summit which occasionally overflow on the south side of the volcano. [1] It is notable for holding the longest-existing lava lake, present since at least 1906. [4] Volcanoes with lava lakes are rare: there were only eight in the world reported in 2019. [5]
A lava tube is a type of lava cave formed when a low- viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface.

Often the lava drainback had a higher rate of flow than the eruptions. [8] With every filling and draining of the lava lake, a 'black ledge' was formed along the rim of the crater which marked the level of the lava lake during each eruption episode. [6] [8] During lava drainbacks, a giant counter-clockwise whirlpool would form. [4]
