Between January 14-15, 2022, volcanic eruptions destroyed much of Hunga Tonga-Hunga Ha'apai, an uninhabited island in the Tonga archipelago in the southern Pacific Ocean. A plume of ash rising 36 miles into the atmosphere blanketed the neighboring Tongan islands.

Seafloor features such as sulfide mounds and chimneys are prominent evidence of hydrothermal activity. These features, whether active or dormant, are just the tip of the iceberg, so to speak; much of the “plumbing” of hydrothermal systems exists beneath the seafloor surface.

Mississippi leads the U.S. in catfish production. The blue tinted shapes in these Landsat images mark ponds where catfish are raised.

The installation of thousands of rock detention structures in the Turkey Pen Watershed, of the Chiricahua Mountains in SE Arizona, provided a 30-year case study to consider low-tech and low-cost Natural Infrastructure in dryland watersheds.

Critical to scientific operations aboard the Escanaba Trough expedition is the submersible robots Sentry and Jason. Owned and operated by the Woods Hole Oceanographic Institute (WHOI), these robots allow researchers to observe seafloor features and collect data from depths seldom visited by humans.

For scientists aboard the Escanaba Trough expedition, obtaining sediment cores or deep-sea biological and geological samples after a Jason dive is only the beginning.

Ecosystems are transforming under climate change, with substantial shifts in ecological processes (e.g. fire, landscape connectivity) and important ecosystem services (e.g. pollination, water filtration) occurring at unprecedented rates.

Embarking on a three-week deep-sea research expedition requires a lot of preparation. For this expedition to Escanaba Trough, U.S. Geological Survey scientists and partners spend the first few days in port, building their laboratory space aboard the research vessel Thomas G. Thompson.

This monthly video update of activity at Yellowstone Volcano comes to you from Mammoth Hot Springs, in Yellowstone National Park, where the Yellowstone Volcano Observatory consortium had its first face-to-face meeting in four years.

Coastal wetlands are among the most productive and valuable ecosystems in the world—comparable to even rainforests and coral reefs.

This timelapse sequence shows one image per day over the past two months 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.

Lava lake activity continues in Halema‘uma‘u, at the summit of Kīlauea Volcano. A small stream of lava was pouring into a small pond northwest of the main lava lake, near the west vent.

Using Military Remote Sensing Technology to Support Federal Civil Agency Science: Sunk Cost, Well Spent

By Paul M. Young, Director of the USGS National Civil Applications Center

During September 2017, Hurricane Maria triggered >70,000 slope failures throughout the mountainous regions of Puerto Rico (USA). Since then, the USGS has had a multi-faceted team working to understand landslide hazards in Puerto Rico.

An overflight at approximately 10 a.m. on May 10, 2022, provided aerial views of the eruption within Halema‘uma‘u crater. Lava continues to erupt from the west vent area, supplying an active lava pond in the western portion of Halema‘uma‘u within Kīlauea summit caldera.

Building and maintaining a landslide hazards program as a state agency presents many opportunities and challenges.
