Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F).

Jan 19, 2025 · lava, magma (molten rock) emerging as a liquid onto Earth’s surface. The term lava is also used for the solidified rock formed by the cooling of a molten lava flow. The temperatures of molten lava range from about 700 to 1,200 °C (1,300 to 2,200 °F).

3 days ago · Kilauea volcano began erupting and shooting lava into the air once again Tuesday on the Big Island of Hawaii. The latest release of molten rock began 10:16 a.m. with lava flowing on to the floor ...

2 days ago · Kilauea volcano on Hawaii's Big Island began erupting this week for the ninth time since December, shooting lava over 300 feet into the air. One of the world's most active volcanoes, Kilauea ...

3 days ago · HONOLULU (AP) — Kilauea volcano began shooting lava into the air once again Tuesday on the Big Island of Hawaii. Kilauea, one of the world’s most active volcanoes, has been erupting on and off for nearly two months since it burst to life on Dec. 23.The eruption has been taking place at the volcano’s summit crater inside Hawaii Volcanoes National Park.

Jul 5, 2023 · Lava flow - An outpouring of molten rock from a vent onto Earth's surface during an effusive volcanic eruption; also the resulting solidified body of rock. Lava flow field - A body of lava, consisting of one or more lava flows, that is the product of a single eruption.

Nov 15, 2024 · Volcanic eruptions on Earth usually send hot lava, hot gases or ash into the air and across surrounding land. In colder parts of the solar system, eruptions often involve liquid water spraying out through cracks in an icy crust. This happens on Enceladus, a moon of Saturn that is covered in ice.

2 days ago · Back in 1959, the volcano spewed an "awesome and terrifying" lava fountain 1,900 feet (580 m) above its vent, according to the USGS. But even Tuesday's eruption posed problems to USGS equipment.

Molten rock below the surface of the Earth that rises in volcanic vents is known as magma, but after it erupts from a volcano it is called lava. Magma is made of molten rock, crystals, and dissolved gas—imagine an unopened bottle of soda with grains of sand inside.

Magma that has erupted is called lava. Some volcanic eruptions are explosive and others are not. The explosivity of an eruption depends on the composition of the magma. If magma is thin and runny, gases can escape easily from it. When this type of magma erupts, it flows out of the volcano. A good example is the eruptions at Hawaii’s volcanoes.
