Aerial view of Excelsior Geyser (in the foreground) and Grand Prismatic Spring in Yellowstone’s Midway Geyser Basin. The colors around the thermal features are locations of different thermophile communities. These thermophiles fix carbon, both from the atmosphere and from the hot water.

This is an oblique, aerial view into the active crater of Anatahan on May 29, 2006, located on the eastern side of the island. Gas plumes were rising form new dome material within the crater where a small crater lake appears with a bright green color.

In this north shore view of Alamagan (Commonwealth of the Northern Mariana Islands) on May 21, 2006, sparse clouds were covering the shoreline. The photo was taken as scientists and volunteers from the Hawaiian Volcano Observatory returned from site visits on Pagan (located approximately 30 miles north of Alamagan).

In this west shore view of Guguan (Commonwealth of the Northern Mariana Islands) on May 21, 2006, cinder cones and lava flows are visible. The photo was taken as scientists and volunteers from the Hawaiian Volcano Observatory returned from site visits on Pagan (located approximately 50 miles north of Guguan).

Lava delta at East Lae‘apuki on the southeast coast of Kīlauea Volcano is about 17 hectares (43 acres). The delta extends about 400 m seaward from the sea cliff and is about 850 m long parallel to the shoreline. The steep sea cliff embayment resulted from collapses of earlier deltas; the collapses undermined and took away parts of the cliff.

Substantial cracks cutting across a lava delta are clear indication that the delta is subsiding as it grows across the unstable pile of interfingering lava flows and fragments built on the steep submarine slope. The larger cracks on this delta are 1-2 m (3-6 ft) wide.

Along the west shore of Pagan Island, this is a view south-southwest to Togari Mountain (third highest peak) and South Volcano to the far right. Fieldwork by USGS Hawaiian Volcano Observatory scientists and volunteers spanned 10 days in the Northern Mariana Islands in May 2006.

This view from Togari Mountain, looking north to the recently active Mount Pagan is a panoramic view from May 10, 2006. A team of Hawaiian Volcano scientists and volunteers assessed volcanic and seismic hazards in collaboration with the Saipan Emergency Management Office.

In this south shore view of Anatahan (Commonwealth of the Northern Mariana Islands) on May 8, 2006, steam plumes were rising from the central crater. This was an early view of the island as scientists and volunteers from the Hawaiian Volcano Observatory prepared for site visits on Pagan (located approximately 116 miles north of Anatahan).

View of the west coast of Saipan, looking at the Tanapag Harbor. Puntan Sabaneta (the area of Banzai Cliff) is at the far left of this photo (north part of the island). The active, subaerial volcanic island of Anatahan is about 70 miles north of Saipan. The active seamounts of Ruby and Esmeralda Bank are within 30 miles of Saipan to the southwest and northwest.

Old Faithful Geyser in eruption. Under Yellowstone Research Permit YELL-SCI-8030, 13 mineralized wood specimens were collected from the geyser mound. The dates of the mineralized wood samples imply that such eruptions did not take place for over a century between the mid-13^th to mid-14^th centuries.

SEM (Scanning electron Microscope) image of a vesicular ash particle erupted by Augustine volcano on January 13, 2006. The ash sample was collected during the ashfall in Homer, Alaska by John Paskievitch, AVO.

Map as of 1:00 p.m. HST, July 11, 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.

Helicopter overflight photo taken this morning - view toward the west directly above Kapoho Crater. The fissure 8 lava channel now bends sharply to the south on the western edge of the crater after being blocked and diverted yesterday.
