(BIVN) – The eruption of Kilauea volcano continues at the summit caldera. While the alert level was downgraded on Monday evening from WARNING to WATCH, lava is still erupting from multiple vents and filling the lava lake in the Halemaʻumaʻu crater.
Today, the USGS Hawaiian Volcano Observatory released some new video, showing the active lava fissures. Scientists say the west vent continues to be the most vigorous source, with occasional bursts up to 20 meters, or 66 feet. The lava lake has risen to the base of the west vent, around which a spatter rampart is being built.
Over the past 24 hours, the lava lake level has risen approximately 1 meter, or 3 feet.
Seismicity and volcanic gas emission rates remain elevated. Sulfur dioxide readings remain high, with preliminary measurements on October 4th of approximately 7,000-9,000 tonnes per day. Summit instruments continue to record deflationary tilt.
The USGS published this reference map on October 5th. It shows the location of the two eruptive vents that were active at the time the map was made. It also shows the position of several islands on the lava lake surface that were present during the previous five month eruption that started in December 2020. Some of these islands were initially drowned by lava but later floated back to the surface. The surface of the lava lake is now at approximately 2,530 feet, or 771 meters, above sea level. Active lava is now visible from two public visitor overlooks in Hawai‘i Volcanoes National Park.
All lava activity remains confined to the summit within Hawai‘i Volcanoes National Park, and no unusual activity has been observed in the East Rift Zone.
