The youngest and most active volcano on the Hawaiian island of Calavia has begun to erupt. According to the U.S. Geological Survey, the eruption began at about 6:20 p.m. The blast is currently limited to a pit inside the Hawaiian Volcano National Park. Scientists are monitoring it with the USGS Hawaii Volcano Observatory.
HVO has updated the warning level from “clock” to “warning”, indicating that “a dangerous outbreak is imminent, ongoing, or suspected.”
Halemaumau is a crater, due to falling surface, it is located inside the Kilauea caldera. Caldera is formed when a volcano erupts, its magma chamber empties to the ground and destabilizes the surface. Eventually, the whole earth falls inwards, and you get a huge depression on the surface of the earth.
For most of 2019, Halimumao was flooded – it turned into a lake. But the eruption in December 2020 showed the vents feeding in lava, boiling water and forming a “lava lake” that was 750 feet deep. It lasted until May 2021 when the lake crusted – but it is active again.
According to the USGS, new cracks have opened up on Lake Lava. “High levels of volcanic gas are a major concern, as it could have far-reaching effects,” the agency said.
