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.

 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. This fissure feeds a small

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. The K2cam is a research camera mounted in the observation tower at the previous Hawaiian Volcano Observatory building on the rim of Kīlauea caldera within Hawai'i

Lava returns to Halema'uma'u, at the summit of Kīlauea Volcano. During a helicopter overflight on December 21, 2020, at approximately 11:30 AM HST, Hawaiian Volcano Observatory scientists observed the northern fissure and lava cascade (right) supplying the majority of the lava into the lake, while the western (left) fissure was feeding several small channels that were

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. Additional photos and video are available at https://www.usgs.gov/

This video tutorial shows how to use the National Map’s 3D Elevation Program (3DEP) Elevation web service in ArcMap. By the end of this lesson, you will be able to add the Dynamic Elevation Web Coverage Service to ArcMap, enable raster processing templates, and retrieve a spot elevation.

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 presentation examines the interplay of old and new magma, and the importance of collecting samples during an eruption and over longer periods to create time series information that can reveal where a volcano is in its life

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. In the May 4th image 3 days after

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. Over the past 100 years, there have been significant advances in banding science. One

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.

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. Reintroducing fire and its

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. En consecuencia, los regímenes de incendios se han modificado a lo largo de la historia, mediante quemas intencionales para promover sus beneficios o mediante

The Volcano Disaster Assistance Program (VDAP) is a partnership of the USGS and USAID. Now in its 34th year, VDAP performs a combination of in-country and remote responses to volcanic crises. Though forecasting volcanic eruptions remains a challenge, advances in technology and our understanding of volcanoes means we are better equipped to track volcanic unrest and forecast
