Acropora palmata coral-reef framework in the Dry Tortugas National Park, Florida Keys built more than 3000 years ago. That framework, which serves as the foundation for all of the critical ecosystem services reefs provide to society, is now rapidly eroding away.

Relict Holocene coral-reef framework in the Florida Keys. Like many reefs in the western Atlantic, reefs here were just a few coral species: primary Acropora palmata and Orbicella spp. Recent disturbances have led to declines in the populations of those corals and relative increases in the abundance of more weedy taxa.

Source and Use of Water in the United States, 2015

This diagram uses a "cylinder and pipe" layout to show the source (surface water or groundwater) of the Nation's water and for what purposes the water was used in 2015. The data are broken out for each category of use by surface water and groundwater as the source.

Map as of 9:00 a.m. HST, June 18, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Fissure 8 lava fountains obscured by a longer exposure photograph taken early morning on June 18. The incandescent spots along a horizontal line mark the edge of the lava channel.

Fissure 6 (photo center) showed signs of activity overnight, producing small amounts of spatter and feeding short lava flows. Fissure 6 is located about 2.2 km (1.4 mi) downrift from Fissure 8.

Fissure 8 lava flows in an open channel all the way to the ocean. Kapoho Crater is the vegetated hill on the right side of the photograph.

North side of the growing Halema‘uma‘u crater, marked by large cracks and large blocks that have slumped into the crater.

During the helicopter overflight on June 18, crews captured this image of the growing Halema‘uma‘u crater viewed to the southeast.

An overflight of Kīlauea's summit on June 18 showed the continued dramatic slumping and collapse of the Halema‘uma‘u crater area. This photo shows the area north-northwest of Halema‘uma‘u near a GPS station, North Pit. This station has subsided about 60 m (197 ft) in the past week.

This animated GIF shows a sequence of radar amplitude images that were acquired by the Agenzia Spaziale Italiana CosmoSkyMed satellite system. The images illustrate changes to the caldera area of Kīlauea Volcano that occurred between May 5 and June 18 at about 6:00 a.m. HST.

An HVO geologist uses a thermal camera to measure the temperature (about 93 degrees C or 200 degrees F) of a ground crack near fissure 9.

As magma in a shallow reservoir beneath the summit drains into the East Rift Zone, the ground above it sags, cracks and subsides. The Halema‘uma‘u crater has dropped about 400 m (1300 ft) between early May and late June. Inward slumping of the surrounding Kīlauea Crater floor has doubled the diameter of Halema‘uma‘u.
