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 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.

This video animates the 1:75,000 scale geologic map of Jezero crater, Mars, which is the landing site for the Mars 2020 mission and Perseverance rover, scheduled to land in February, 2021.

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.

Just what is the Yellowstone Volcano Observatory? In this video, Mike Poland, Scientist-in-Charge of YVO, gives an overview of the institutions that make up the Observatory, how YVO monitors volcano and earthquake activity at Yellowstone, the geologic hazards of the region, and some of the noteworthy new results and observations from YVO scientists.

USGS–Hawaiian Volcano Observatory Geophysicist Jefferson Chang talks about technologies that track activity at Hawaiian volcanoes and how crowdsourcing and citizen science can contribute to a greater understanding of hazards, in this presentation to the 2020 SACNAS Advancing Hispanics/Chicanos & Native Americans in Science virtual conference held October 19-24,

Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland visits Yellowstone National Park to tell the story of how the ground there moves up and down over time. This motion has been measured using a variety of techniques over the past 100 years, and from geological mapping scientists can even tell how the ground has moved going back about 15,000 years!

Join the USGS St. Petersburg Coastal and Marine Science Center on an adventure in the field! Our team of scientists will take you on board a personal watercraft near downtown St. Pete to show you how they collect bathymetry data – which is the depth of the ocean floor (in this case, Tampa Bay). This video was created as part of the 2020 St.

A helicopter overflight on September 23, 2020, provided airborne views of the water lake at the summit of Kīlauea Volcano. Visual and thermal images collected during the overflight are used for mapping the slowly enlarging lake. A segment of the video shows the remains of Crater Rim Drive, a portion of which collapsed during the 2018 summit activity.
