The island of Puerto Rico is subject to numerous natural hazards including hurricanes and coastal erosion. Information on how the island’s coastal environments respond to these events is critical for bolstering coastal resilience. Dr.

Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone in this monthly update for October 1, 2022. 

The update comes to you from Artist Paintpots in Yellowstone National Park. The paintpots are acid sulfate springs, one of three different types of thermal features in Yellowstone. 

Kīlauea volcano's summit eruption, within Hawai‘i Volcanoes National Park, began one year ago—on September 29, 2021. This three-minute video, produced by the Hawaiian Volcano Observatory, features footage from the past year and summarizes the eruption.

This timelapse sequence shows one image per day since March from the B1cam webcam on the east rim of Halema‘uma‘u, at the summit of Kīlauea. The images show that the floor of Halema‘uma‘u has been growing endogenously.

A routine helicopter overflight of the summit of Kīlauea provided airborne views of the lava within Halema‘uma‘u crater. The active lava lake is limited to the western portion of the crater floor, near the main source of white fume. The remainder of the crater floor consists of solidified lava flows.

Landsat satellites have watched the Brunt Ice Shelf for nearly five decades. And now, Landsat 9 has joined in observing the changing surface.

Evening views of the eruption within Halema‘uma‘u crater on September 8, 2022. Solidified crust founders and sinks at the lava lake margin, and the lava lake sloshes. Lava spatters along the margin of the lake. 

This video provides an overview of the science and products produced by the U.S. Geological Survey Woods Hole Coastal and Marine Science Center, as well as the use and value of the knowledge, data, and tools produced by the Center. It additionally highlights the Center’s location, where we conduct research, and collaborator/stakeholder types.

The familiar saying “good things come in small packages” holds especially true for deep-sea biological communities at hydrothermal vents, including those at Escanaba Trough, a seafloor spreading center located almost 200 miles off the northern California coast.

This time-lapse sequence is shown at 100x speed and shows the motion of the lava lake in Halema‘uma‘u, at the summit of Kīlauea. Lava enters the lake at the west end (bottom of image) and flow steadily towards the east end, where the crust is consumed along the lake margins. 

This timelapse sequence shows activity in Halema‘uma‘u, at the summit of Kīlauea, from March to August. The video shows the rise of the crater floor due to lava supplied beneath the surface crust, lifting the crater floor in an "endogenous" process. In addition, lava flows erupt sporadically and resurface portions of the crater floor.

El aumento de riesgos por inundaciones a lo largo de nuestras costas está causado por el cambio climático, el desarrollo urbano y la pérdida de hábitat.

Coral reefs are important for supporting biodiversity, fisheries, tourism, and coastal protection, but are in decline worldwide, primarily due to extreme heat waves and subsequent coral bleaching, in addition to other stressors.

The complex, three-dimensional reefs built by corals over hundreds to thousands of years provide invaluable ecosystem services to society—contributing billions of dollars per year to the global economy through shoreline protection, tourism, and habitat for biodiversity and fisheries.
