USGS station ID 01075000 Pemigewasset River at Woodstock, New Hampshire. The high-water mark monument was installed in May 2021, and shows the peak for the period of record at this gage was from Tropical Storm Irene. It still remains the highest peak to this day. This gage has reported peaks for 77 years.

The Prime Hook National Wildlife Refuge in Delaware is the site of a $40 million tidal marsh restoration project—one of the largest restoration projects ever in the eastern U.S. With this project, the U.S. Fish and Wildlife Service aims to restore 4,000 acres of highly damaged tidal marsh and barrier beaches to improve the ability of the marshes to withstand future storms

In the Mississippi River Birdfoot Delta, there is intense vegetation loss in marshes farthest away from the river, as indicated by high values of UVVR (shown in pink). In the past, these marshes were naturally replenished by the Mississippi River sediment supply, but human activities have disrupted this natural process—causing these sediments to instead go straight down

Within the busy boroughs of Brooklyn and Queens, New York City, is Jamaica Bay—a complex urban ecosystem almost the size of Manhattan that consists of salt marsh islands, various waterways, meadowlands and two freshwater ponds. This ecosystem is a true natural treasure to New York, providing protection from storms, a haven for migratory and resident bird and fish species,

Everglades National Park in South Florida is the largest subtropical wetland ecosystem in North America, consisting of about 1.5 million acres of mangrove forests and other coastal wetlands. Mangroves are salt-tolerant trees that thrive amidst the harsh growing conditions of the coast. Like other coastal wetlands, the mangroves in the Everglades stabilize the coastline,

View looking to the east of the western part of the now inactive lava lake in Halema‘uma‘u at the summit of Kīlauea Volcano, taken on May 28th. The west vent area is at the bottom. The glowing vent area in the photo taken in the evening on May 24th is visible in the bottom right, with a white rim at the top of the now inactive vent. Part of the main island is visible in

This close-up view of the now-inactive western fissure within Halema‘uma‘u at the summit of Kīlauea was captured on Thursday, May 27, 2021. HVO scientists did not observe any incandescent lava or other signs of eruptive activity during a one-hour visit to the crater rim. The fissure complex was measured to be about 20 m (66 ft) tall at the time; small rockslides have been

Kīlauea Volcano is no longer erupting. Lava supply to the Halemaʻumaʻu lava lake has ceased and sulfur dioxide emissions have decreased to near pre-eruption background levels. Yesterday, the USGS Hawaiian Volcano Observatory (HVO) lowered the Kīlauea Volcano Alert Level for ground based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW. This

A wide view of the now inactive lava lake and west vent from the western rim of Halema‘uma‘u, at Kīlauea summit. The lava lake is entirely crusted over with no red, glowing lava at the surface. Diffuse volcanic gas plumes are still being emitted from the west vent and northern lake margin. This photo was taken in an area of Hawai‘i Volcanoes National Park that remains

An overview of the lava lake within Halema‘uma‘u crater, at Kīlauea Volcano’s summit, taken on May 25. Kīlauea’s summit collapse in 2018 deepened Halema‘uma‘u crater by over 500 meters (1640 feet). The eruption that began the evening of December 20, 2020, has filled approximately 229 m (751 ft) of the base of Halema‘uma‘u crater, which is more than the height of the Space

Though no active surface lava was observed within Halema‘uma‘u on May 25, Kīlauea summit continues to emit volcanic gases. The most recent sulfur dioxide emission rate, measured on May 23, remains slightly elevated at 100 tonnes per day. This photo, taken from the south rim of Halema‘uma‘u, shows an area near the north wall of Halema‘uma‘u crater that has been visibly

During an eruption monitoring shift on May 25, HVO field crews did not observe any active surface lava or incandescent areas within Halema‘uma‘u crater, at the summit of Kīlauea. Since the eruption began on December 20, 2020, over 40 million cubic meters (over 10 billion gallons) of lava has been erupted. This volume is approximately 16 times the volume of the Great

A zoomed-in view of the western lava lake in Halema‘uma‘u, at Kīlauea summit, where two locations of faint incandescence are visible beneath the surface crust (upper right). Eruptive activity has decreased significantly in the past few weeks and the once active lava surface has cooled and crusted over. USGS photo taken by B. Carr at dusk on May 24, 2021.

On the evening of May 24, no active surface lava was observed within Halema‘uma‘u crater, at the summit of Kīlauea Volcano. Small spots of incandescent lava were visible beneath cracks in the lake surface crust (center) and at the west vent (left). This photo was taken from the western rim of Halema‘uma‘u, in an area of Hawai‘i Volcanoes National Park that remains closed

A close-up view of the northeastern rim of the Halema‘uma‘u lava lake, at the summit of Kīlauea. This area of the lava lake has been degassing persistently for the past few months. Several large boulders, which fell from the crater walls, are visible near the perimeter of the northern lava lake crust (center). The top of the inactive northern vent cone is visible in the

A close-up view of the western fissure vent complex and gas plume within Halema‘uma‘u, at the summit of Kīlauea. Gas emissions remain slightly elevated, with the most recent measurements on May 18 at 100 tonnes per day. The lava inlet from the base of the west vent, which no longer appears to be active, is visible on the right. USGS photo from the southern rim of Halema‘

No active surface lava was visible within Halema‘uma‘u, at the summit of Kīlauea, during a field visit yesterday morning. F1cam thermal images from yesterday afternoon show hot surface crust, but no active lava. F1cam thermal images from the morning of May 21 showed at least one small resurfacing event. This image was taken within an area of Hawai‘i Volcanoes National Park

Map and plot showing earthquakes at 20-40 km (12-25 miles) depth beneath the Island of Hawai‘i over the past week. Most of the earthquakes at this depth were clustered beneath the southern edge of the island near the town of Pāhala (blue dots).  USGS graphic.

Active surface lava in Halema‘uma‘u, at the summit of Kīlauea, is now limited to a small lava pond near the western fissure. Normally the lava pond is covered in a stationary crust, as shown by the image on the left. Occasionally, the pond abruptly resurfaces with fluid lava, with foundering of crustal plates and abundant bubbling, shown by the image on the right. The

A groin at Seven Mile Island, New Jersey traps sand and contributes to widening of the barrier beach. This illustrates how human modification and wave processes shape the beach. In May 2021, Andrew Farmer, Chelsea Stalk, and Emily Wei conducted a multibeam bathymetry survey offshore of Seven Mile Island, along the southern coast of New Jersey. A similar bathymetry survey

This comparison of thermal images taken from the south rim of Halema‘uma‘u, at the summit of Kīlauea, show the diminishing area of active lava on the surface over the past month. Today, active lava was limited to a small pond, about 20 meters (yards) long, near the western fissure. USGS images by M. Patrick.

This close-up view of the of the Halema‘uma‘u lava lake at the summit of Kīlauea was captured on Tuesday, May 18. During an approximately one-hour visit to the crater rim, USGS Hawaiian Volcano Observatory scientists' only observation of active lava was the crustal foundering event captured here, which lasted approximately five minutes. All that remains of the active lava

The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active, although surface incandescence (glowing red lava) has become less frequent over the last few days. In this view looking northwest, two elongated lobes oriented west (left) to east (right) with a relatively smooth shiny grey surface are visible in the center of the photo. These two lobes
