Kilauea volcano ERUPTION: Watch incredible footage of lava lake overflow in Hawaii | Science | News


The video was captured by the U.S. Geological Survey (USGS) Hawaiian Volcano Observatory (HVO) on April 25.

The event is just one in a series of overflows occurring at Kilauea, with the most current recorded on Thursday.

A statement on the USGS website said: “At approximately 6.15am today (April 26) a new overflow began on Halema’uma’u crater floor.

“The lava lake overflow continued until about 10.30am and covered about 36 hectares (90 acres) of the crater floor with lava.”

Since April 21,high lava lake levels in the ‘overlook crater’ within Halema’uma’u at the summit of Kilauea Volcano have produced multiple overflows onto the floor of Halema’uma’u.

As of April 26, the new flows have covered just under 90 acres or nearly three/fourths of the Halema’uma’ crater floor.

Scientists from USGS said the lava lake in the west pit of Kilauea has risen by 23 feet.

Experts are calling the recent activity the largest lava overflow observed at the site in a decade.

The overflows are said to happen due to the increased build-up of magma inside the volcano, causing a spatter of gas bubbles within the lava lake to burst and come up to the surface.

The Pu’u ‘O’o cone has been inflating and expanding steadily since mid-March, which has caused the main crater floor to uplift and crack and small lava flows to flare up intermittently inside the active.

The USGS said when this happened previously, it resulted in new breakouts of lava from new vents on the Pu’u ‘O’ o cone.

The magmatic plumbing system extending from the summit reservoir to Pu’u ‘O’o is pressurising, which means an excess of magma is being stored in the system.

This has caused swelling and an increase in the height of lava lakes at both the summit and the Pu’u ‘O’o cone.

Kilauea has been continuously erupting for three decades and is considered one of the world’s most active volcanoes.

It is the youngest and most active Hawaiian shield volcano, located on the southern part of the Island of Hawaii, known as Big Island.
