Critical to scientific operations aboard the Escanaba Trough expedition are 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.

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.

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.

What is a seismic survey? This video gives a very brief overview of the what goes into conducting a seismic survey in an urban area. The survey depicted in this video was done in San Carlos, California.

A morning overflight of Kīlauea summit on March 2, 2022, provided aerial views of the eruption within Halema‘uma‘u. Lava erupts from the west vent area and pours into the active lava lake area. 

This monthly update from the Yellowstone Volcano Observatory begins with a story.

USGS geologist Dan Dzurisin is near Sisters, in Central Oregon, to set up portable GPS monitoring equipment to track something that's been going on for 25 years and still goes on today. It’s uplift, a subtle rise in the ground’s surface, in an area west of South Sister volcano.

Some people have characterized the seasonal rise and fall of Yellowstone as being like breathing. During the summer there is a little pause in the overall trend of subsidence and sometimes even a short episode of slight uplift. The trend reverses in early winter.

Lava continues to erupt from the west vent in Halema‘uma‘u, and supply the lava lake through a spillway in the spatter cone. On November 12, a small overflow of the perched lava lake levee was visible from the western crater rim. Overflows are an important process for building up perched levees, as they help add height and stability.

Lava continues to erupt from the west vent in Halema‘uma‘u, and supply the lava lake through a spillway in the spatter cone. On November 9, a close-up view of the west vent shows spatter bursting and sloshing within the cone. Spatter was thrown about 6–9 m (20–30 ft) above the pond surface, occasionally depositing spatter onto the rim of the cone. 

The November 2021 YVO Yellowstone Volcano update comes to you from a very snowy Norris Geyser Basin with a story about Porkchop Geyser’s 1989 explosion.

Eruptive activity continues in Halema‘uma‘u, at the summit of Kīlauea. The west vent remains active with low fountaining in a slightly perched pond set within the cone. Lava pours through a short spillway into the lava lake. The base level of the pond fluctuates over the timespan of minutes.

It has been one month since the new eruption began in Halema'uma'u. Over the past year at Kīlauea summit there has been a water lake and two eruptions within Halema'uma'u crater.

Eruptive activity continues in Halema‘uma‘u crater, at the summit of Kīlauea. The west vent remains active with low fountaining in a slightly perched pond set within the cone. Lava pours through a short spillway into the lava lake.

A morning overflight of Kīlauea summit on October 15, 2021, provided aerial views of the eruption within Halema‘uma‘u. Lava erupts from a single vent on the western wall of the crater. The vent has a spatter cone around it, with an opening to the east from which lava flows into the lava lake.

Lava continues to erupt from the western vent in Halema‘uma‘u. On October 12, a short-lived vent (erupting for approximately 10 hours) was present to the north of the main vent (right). Lava fountaining from the main vent was 10–15 meters (30–50 ft) above the lake surface, with larger bursts exceeding the height of the cone (30 meters or 100 ft).
