Kilauea eruption triggers red alert on Big Island of Hawaii

Kilauea is one of the most active volcanoes in the world.

Kilauea, one of the most active volcanoes in the world, has started erupting again, according to the US Geological Survey.

A red alert means that a volcanic eruption is imminent, in progress or suspected, with potentially dangerous activity on the ground and in the air.

Due to the remote location of this eruption, the main hazards are aerial hazards from gas emissions and windblown tephra (rock fragments) from the eruption, the USGS said. Current volcanic activity is limited to the summit region and no lava is visible from accessible areas of the park.

The eruption occurred about a mile south of the Kīlauea caldera and north of the Koa’e Fault System and Hilina Pali Road in Hawaii Volcanoes National Park, but in a closed area and rugged, according to the USGS.

The open fissure is more than a mile long, a USGS spokesperson told ABC News. The lava varied in height and force, with some eruptions spewing up to 65 feet, the spokesperson said. Gas was also being emitted from the fissure, the spokesperson noted, and the last time there was an eruption like this was in 1974, which was much larger and covered a much larger area. vast.

The lava flows are thin and have traveled only a few hundred meters from the fissures, the USGS said. Many large cracks in the ground formed near the eruption.

This eruption could last from a few hours to a few days, the spokesperson said.

Authorities have not yet observed Pele’s hair – a formation of volcanic glass produced from lava cooled and stretched into thin strands – at the site.

Authorities are closely monitoring the volcano for signs of increasing or decreasing activity, the USGS said. Researchers are also collecting data on emissions of volcanic gases and steam emitted from the eruptive fissure and nearby fissures.

More than 400 earthquakes occurred in the past 24 hours, with most occurring between noon Sunday and midnight Monday, just before the eruption began, the USGS said. The largest earthquake, with a magnitude of 4.1, occurred on Sunday at 9:12 p.m.

Past eruptions of Kilauea have proven destructive. A strong lava flow destroyed more than 600 properties in 2018 as it moved from the summit of Kilauea to the ocean.

A mechanism similar to a “toy rocket” contributed to the severity of the lava flow that year and could affect future eruptions in the same way, according to a paper published last week in Nature Geosciences.

The continued eruptions since 2018 have not been as severe.
