27 December 2020 - Kīlauea Volcano US Geological Survey Hawaiian Volcano Observatory - Evening views of the eruption in Halema‘uma‘u. The west vent remained active overnight, with strombolian-like bursts and lava cascades. Lava cascading from the vent plunges into the lava lake in multiple places, causing local upwelling.

A helicopter overflight on December 26, 2020, provided aerial views of the eruption in Halema‘uma‘u. This video, which is sped up 3 times, shows the lava lake and active west vent that rejuvenated just before 3 a.m. HST today. Visual and thermal imagery collected during the overflight are used to map the ongoing activity.

Unoccupied Aircraft Systems (UAS) video clips of the eruption within Halema‘uma‘u crater at Kīlauea Volcano’s summit. This collection of video clips from December 25, 2020 taken with UAS shows the then-dominant north vent fountain and occasional weak spattering from the west vent.

This thermal timelapse (from F1cam webcam) shows the switch from water lake to lava lake in Halema‘uma‘u, spanning December 20 to December 24. During the initial phase of lava appearing in the crater, a large steam plume is generated as lava interacts with and boils off the water lake.

23 December 2020 - Kīlauea Volcano US Geological Survey Hawaiian Volcano Observatory. Clip 1: A mid-day helicopter overflight provided aerial views of the eruption in Halema'uma'u crater. This video shows two active fissures erupting lava into a growing lava lake. Visual and thermal images collected during the overflight are used to map the ongoing activity.

Two fissure vents feed a growing lava lake at the bottom of Halema‘uma‘u crater. A preliminary calculation of volume suggests that since the start of the eruption on December 20, 2020, approximately 8-10 million cubic meters of lava have been erupted. This is equivalent to over 2 billion gallons, the volume of 3,000 Olympic-sized swimming pools.

Fissures Feed a Lava Lake at Halema'uma'u, at Kīlauea Volcano's Summit. Since fissures opened on December 20, 2020 in Halema'uma'u crater, USGS–Hawaiian Volcano Observatory scientists have maintained a 24-hour watch from the rim, taking measurements and making visual observations.

Telephoto videos capture fissure activity within Halema‘uma‘u crater on December 22, 2020, at approximately 3:35 PM HST. (1) The first video shows the main northern fissure. The lava fountains have built up a horseshoe-shaped spatter cone (dark in color) around the perimeter of the vent. (2) 2) The second video shows the smaller western fissure.

On December 20, 2020 just after 9:30 PM HST, lava began flowing from three fissure vents inside the crater of Kīlauea. The water lake at the base of the Halema'uma'u crater has boiled off. Lava is now feeding a growing lava lake.

Arc volcanoes often show evidence for new magma coming from the lower crust and interacting with old magma in the shallow crustal storage system.

This timelapse sequence shows 3.5 hours of activity at the water lake in Halema‘uma‘u crater, at the summit of Kīlauea Volcano. Several influx zones supply groundwater into the lake from the margins, creating shifting color zones on the lake surface. No significant changes have been observed in recent lake activity. USGS video by M. Patrick.

La relación entre la gente y los incendios forestales siempre ha sido paradójica: el fuego es esencial como proceso ecológico y herramienta de gestión, pero también puede ser perjudicial para la vida y la propiedad.

The relationship between people and wildfire has always been paradoxical: fire is an essential ecological process and management tool but can also be detrimental to life and property. Consequently, fire regimes have been modified throughout history through both intentional burning to promote benefits and active suppression to reduce risks.
