Watch River of Lava Pour From Kīlauea Volcano in Incredible Video

An incredible video showing a river of lava pouring out of Hawaii's Kīlauea volcano as it continues to erupt has been released by the National Park Service.

Mount Kīlauea is the most active volcano in Hawaii, and lies on the southeastern part of the island. It has been erupting on and off since 1983 and a particularly destructive period in 2018 saw over 700 homes destroyed.

In this period, the volcano erupted from May through August, when large lava flows covered land to the southeast of the Hawai'i Volcanoes National park. It had devastating impacts on residential areas in the nearby Puna District of the island. The summit area of the park also suffered tens of thousands of earthquakes during the eruption.

Its frequent eruptions however, are usually contained within its most active crater—known as Halema'uma'u—as a boiling lake of active lava.

The video posted to Facebook by Hawai'i Volcanoes National Park shows fountains of vibrant lava protruding from the volcano in the early hours of February 9.

This particular eruption began four months ago on September 29. Its summit has been spouting lava intermittently since then.

Hawai'i Volcanoes National Park said no lava could be seen on February 8, however it suddenly became visible again at 1.20 a.m. local time on February 9. By 4.30 a.m., Kīlauea was putting on a "spectacular" show.

The national park said the volcano continues to "fascinate" them with its "ups and downs." This eruption has produced around 12 billion gallons of lava since it started in September.

"Lava rises, flows and fountains within Halemaʻumaʻu as pressure inflates, then drops, sometimes for days, to unseen levels as it deflates. Rewind, repeat..." the park said.

Michele Paulatto, Geophysicist at Imperial College London in the U.K., told Newsweek that volcanoes often exhibit this type of "cycling" behavior. He said that previous eruptions at Kīlauea have shown intermittent fluctuations over periods as short as five minutes, and long term fluctuations over one to two days.

"If the eruption is contained to the Kilauea crater the hazard is usually limited," he said.

Paulatto said that the eruption only becomes a danger if it extends to its east rift zone, as it did in the destructive eruption of 2018.

"This is because the plumbing system of the Kilauea summit crater is linked underground with the East rift zone and they can erupt together ... for the moment, the current eruption only involves the summit crater and there are no signs that the East rift zone is involved," he said.

The United States Geological Survey (USGS) continues to closely monitor the volcano and look for any changes in its behavior.

The latest update from the USGS determined that the main area for concern remains the high levels of volcanic gas in the area. However the eruption is still occurring in a contained area of the Hawaiʻi Volcanoes National Park.
