A USGS Hydrologic Technician is briefly shown calibrating the compass on a remote controlled Qboat. The Qboat is then sent across the Millers River near South Royalston, Massachusetts to collect discharge data. This video shows the Qboat making several passes across the river.

In 2019, the Volcano Alert Level for Mauna Loa was elevated from “NORMAL” to “ADVISORY” due to increased seismicity and deformation at the volcano. This alert level does not mean an eruption is imminent, but it is a fact that Mauna Loa, which has erupted 33 times since 1843 (most recently in 1984), will erupt again. What will you do when it does?

The 2018 Kīlauea eruption produced unprecedented levels of seismicity in the volcano’s instrumented history. The USGS Hawaiian Volcano Observatory documented about 80,000 earthquakes during the three-month-long eruption, starting with the dramatic collapse of the Puʻu ʻŌʻō cone on April 30 and ending with the final Kīlauea summit caldera collapse event on August 5.

The Rise of the USGS in Space Exploration: How the Astrogeology Science Center is integral to the past, present, and future investigation of the Solar System.

In the year since Kīlauea Volcano’s notable 2018 eruption ended, the lower East Rift Zone has been relatively quiet. But USGS Hawaiian Volcano Observatory scientists continue to gain insight into the eruption through ongoing research and monitoring. Some of the many questions asked by island residents include, Why did the fissures erupt along a linear pattern?

This thermal video of the fissure 8 cone shows that small areas of higher temperatures (greater than 100 degrees Celsius, or 212 degrees Fahrenheit) are present on the cone. Those hotter areas likely represent residual heat in the cone and the underlying fissure. USGS video by M. Patrick.

This video clip shows a flyover of fissure 8 on Jan. 21. During the 2018 eruption, lava spilled out from the cone into a channel that extended towards the north. Lava traveled approximately 13 km (8 miles) to reach the ocean at Kapoho Bay. USGS video by M. Patrick.

The 2018 eruption on Kīlauea’s lower East Rift Zone spewed around a billion cubic yards of lava into Puna. From the moment the eruption began, samples of lava were collected and rapidly analyzed by a team of USGS Hawaiian Volcano Observatory and University of Hawaiʻi at Hilo scientists.

Kīlauea Volcano's summit has been in an eruptive pause since the 2018 events ended over a year ago. Nevertheless, it remains a dynamic place. Ongoing inflation and seismicity indicate that the summit magma chamber is gradually recharging.

The Shishaldin Volcano on the eastern edge of Alaska's Aleutian Island chain erupted with activity in January of 2020. The eruption on the island of Unimak sent an ash cloud nearly 5 miles into the sky on January 7th, sparking ash alerts for aviators, mariners, and residents of nearby communities.

It's winter in the northern hemisphere, but in Antarctica, summer has just begun. At Zucchelli Station the summer solstice occurred on December 22nd, 2019 at 5:19pm local time. The high temperature that day was a balmy 34 degrees Fahrenheit. These images from Landsat 8 show the distinct difference in sun angles cause by the change in seasons.

Tens of thousands of earthquakes occur each year in Hawaii, making it one of the most seismically active places in the United States.

2018 and 2019 were years of profound change at Kīlauea Volcano and the USGS Hawaiian Volcano Observatory. Devastation caused by the largest lower East Rift Zone eruption and summit collapse in at least 200 years resulted in many transitions for island residents, including HVO.

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision-making.
