 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.

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.

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.

Lava returns to Halema'uma'u, at the summit of Kīlauea Volcano.

Lava Returns to Halema'uma'u, as captured in this timelapse from the K2cam, located at the HVO Observation Tower (Kīlauea Volcano). Timelapse is from December 20, 2020, 5:50 a.m. to December 21, 2020, 11:57 p.m.

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.

The western wall of Uzbekistan's Sardoba Reservoir breached on May 1st, 2020 after a week of heavy rain. Thousands were evacuated as water rushed north into farmland and villages across the central Asian country and into neighboring Kazakhstan. Imagery from Europe's Copernicus Sentinel-2 satellite shows water pooling across a wide area.

This year marks the 100-year anniversary of the establishment of the USGS Bird Banding Laboratory. The lab hosted a live webinar to highlight the long history between the Bird Banding Lab and US Fish & Wildlife Services, and how they have impacted avian science in the past 100 years.

The largest gravity changes ever recorded: Continuous gravity monitoring of the onset of Kīlauea’s 2018 eruption Talk by Mike Poland–USGS Yellowstone Volcano Observatory Scientist-in-Charge and former USGS Hawaiian Volcano Observatory geophysicist.

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.

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.
