'''Lava lakes''' are large volumes of molten ], usually ]ic, contained in a volcanic vent, ], 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'' in this case).

===Behaviors===
Lava lakes occur in a variety of volcanic systems, ranging from the basaltic ] lake in Ethiopia and the ] volcano of ], Chile, to the unique ] lava lake at ], Antarctica. Lava lakes have been observed to exhibit a range of behaviours. A "constantly circulating, apparently steady-state" lava lake was observed during the ] of ], Hawai{{okina}}i.<ref>Swanson et al. (1979) "Ground deformation at Pu'u 'O'o. U.S. Geological Survey Chronological narrative of the 1969-71 Mauna Ulu eruption of Kilauea volcano". US Geological Survey Professional Paper 1056</ref> By contrast, a lava lake at the 1983–1984 ] eruption of Kilauea displayed cyclic behaviour with a period of 5–20 minutes; gas "pierced the surface" of the lake, and the lava rapidly drained back down the conduit before the onset of a new phase of lake activity.<ref>Wolfe et al. (1988). "Geologic observations and chronology of eruptive events". US Geological Survey Professional Paper 1463</ref>
The behaviour observed is influenced by the combined effects of pressure within the reservoir, ] and ] of gas bubbles within the conduit and, potentially, exsolution of bubbles within the ] reservoir. Superimposed upon this is the effect of bubbles rising through the liquid, and ] of bubbles within the conduit. The interactions of these effects can create either a steady-state recirculating lake, or a lake level that periodically rises and then falls.<ref>Witham and Llewellin (2006). "Stability of Lava Lakes". '+Journal of Volcanology and Geothermal Research'' vol. 158 p.321–332</ref>

Not to be confused with crater lakes, lakes of water that form in a volcanic crater or caldera. For places named Lava Lake, see Lava Lake. Molten lava contained in a volcanic crater
Lava lake at Nyiragongo Volcano in a molten state. (Democratic Republic of the Congo)
Lava lake at Erta Ale Volcano, Ethiopia.
The lava lake of Halemaʻumaʻu at Kīlauea, Hawaiʻi, United States).
Lava lake in Marum crater, Ambrym, Vanuatu.

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).

Formation

Lava lakes can form in three ways:

  • from one or more vents in a crater that erupts enough lava to partially fill the crater; or
  • when lava pours into a crater or broad depression and partially fills the crater; or
  • atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater progressively higher than the surrounding ground.

Behaviors

Lava lakes occur in a variety of volcanic systems, ranging from the basaltic Erta Ale lake in Ethiopia and the basaltic andesite volcano of Villarrica, Chile, to the unique phonolitic lava lake at Mt. Erebus, Antarctica. Lava lakes have been observed to exhibit a range of behaviours. A "constantly circulating, apparently steady-state" lava lake was observed during the 1969–1971 Mauna Ulu eruption of Kīlauea, Hawaiʻi. By contrast, a lava lake at the 1983–1984 Puʻu ʻŌʻō eruption of Kilauea displayed cyclic behaviour with a period of 5–20 minutes; gas "pierced the surface" of the lake, and the lava rapidly drained back down the conduit before the onset of a new phase of lake activity. The behaviour observed is influenced by the combined effects of pressure within the reservoir, exsolution and decompression of gas bubbles within the conduit and, potentially, exsolution of bubbles within the magma reservoir. Superimposed upon this is the effect of bubbles rising through the liquid, and coalescence of bubbles within the conduit. The interactions of these effects can create either a steady-state recirculating lake, or a lake level that periodically rises and then falls.

Notable examples

Persistent lava lakes are a rare phenomenon. Only a few volcanoes have hosted persistent or near-persistent lava lakes during recent decades:

The lava lakes at Ambrym volcano disappeared after a large eruption in December 2018.

For many years, Kīlauea had two persistent lava lakes: one in the Halemaʻumaʻu vent cavity within the summit caldera, and another within the Puʻu ʻŌʻō cone located on the east rift zone of the volcano. In May 2018, both of these lava lakes disappeared as a result of increased activity in Kīlauea's east rift zone. The lava lake at Halemaʻumaʻu returned in December 2020, after Kīlauea's first eruption in over two years. The lava lake solidified after the eruption ended in May 2021, but returned again when eruptive activity at Halemaʻumaʻu resumed on September 29, 2021. Following the 2021 eruption, three more occurred on January 5, 2023; June 7, 2023; and September 10, 2023. As of January 2024, Halemaʻumaʻu is not erupting and the lava lake is no longer active.

Nyiragongo's lava lake has usually been the largest and most voluminous in recent history, reaching 700 meters wide in 1982, although Masaya is believed to have hosted an even larger lava lake at the time of the Spanish conquest, being 1,000 meters wide in 1670. The lava lake at Masaya came back in January 2016.

In addition to the aforementioned persistent lava lakes, a certain number of occurrences of temporary lava lakes (sometimes called lava ponds or lava pools, depending on their size and nature) have also been observed and are listed in the following table.
