Kilauea volcano eruption:
The US Geological Survey (USGS) has downgraded the safety alert for Kilauea volcano in Hawaii, following a new eruption. The alert level has been reduced from “WARNING” to “WATCH” as effusion rates have declined and no infrastructure is threatened. The previous warning has been lowered to a watch, as high effusion rates have decreased and no infrastructure is considered to be under threat. Aviation warnings have shifted from red to orange also.
Kilauea volcano eruption: Key Points
- Aviation warnings have also been reduced from red to orange. Kilauea, one of the world’s most active volcanoes, is located in a closed national park on the Big Island of Hawaii.
- The ongoing eruption is expected to persist, however, lava flows will continue to be limited to the crater and summit of the volcano.
- Hawaiians are asking tourists to observe the volcano’s eruption from a respectful distance.
While lava flows are expected to remain confined to the surrounding crater and summit, USGS predicts that the eruption will continue.
Kilauea volcano: About
- Kīlauea is a volcano on the southeastern shore of Hawaii’s Big Island.
- It formed about 100,000 years ago and is between 210,000 and 280,000 years old.
- Along with four other volcanoes, it comprises the island of Hawaii.
- Kīlauea is the most active of the five and one of the most active in the world, with recent eruptions in 2021 and 2023.
- Initially considered a satellite of its larger neighbor Mauna Loa, Kīlauea has its own structures, including a summit caldera and two active rift zones extending east and west.
- Halemaʻumaʻu pit crater has hosted an active lava lake, and between 1983 and 2018, Kīlauea experienced nearly continuous eruptions from vents on its eastern rift zone.
- In 2018, activity shifted to the lower Puna district, destroying hundreds of dwellings, Hawaii’s largest natural freshwater lake, and several communities.
- The eruption also prompted the closure of the Kīlauea section of Hawaii Volcanoes National Park. Kīlauea erupted again in 2020 and 2021, draining a water lake to create a lava lake in the Halemaʻumaʻu crater.
