Morning overflight view to the south. The Cape Kumukahi Light can be seen in amongst the flows in the lower portion of the photograph. Ocean entry is still present just offshore of Kapoho with a more robust entry to the south (larger steam plume) near Ahalanui Beach Park.

A NOAA image of the bathymetry north of Puerto Rico. Two ancient submarine landslides are visible as head scarps (labeled Loiza and Arecibo Amphitheaters). Seafloor fissures are indicated by black arrows, and dashed lines outline debris flows from past failures. Map annotated by Uri ten Brink, USGS

Tamarisk stem cross-section cut 2.8 m below the ground surface showing how sediment deposition is dated using tree rings.  Following initial burial of 68 cm in 1969, ring-width decreased, vessel size increased, and annual transitions became less distinct. After a second burial by 41 cm in 1972, annual transitions became indistinguishable.

A multibeam bathymetric survey that produced unprecedented high resolution images of the mouth of San Francisco Bay was conducted in 2004 and 2005.

Mount Baker and Bellingham, Washington on Bellingham Bay.

Mount Adams western profile as seen from Mount St. Helens.

Summit of Glacier Peak, Washington, view toward the east.

This lava delta at Lae‘apuki added about 24 hectares (60 acres) of new land to the southeast coast of Kīlauea in 2006, but 6.5 hectares (16 acres) slid into the sea in 2007. White plume marks location of lava entering the sea through a tube whose location is shown by blueish fume in middle right.

View of the church's front entrance, showing the collapsed wall under the eave, framing, and wall above the doors. The pile of building debris shows why taking cover (Drop! Cover! Hold on!) inside a building is safer than trying to run outside or stand in a doorway when the ground shakes.

This is sagebrush burning at Hart Mountain National Antelope Refuge in association with a management project located 65 miles northeast of Lakeview, OR.

Seismic station at Yellow Rock (YEL) with the toe of the west arm of Crater Glacier in the background. This station site was eventually covered by the glacier.

Lava pours over the former sea cliff at East Lae‘apuki onto an active lava delta (left of cliff). The lava broke out from a lava tube just inland of the sea cliff (right of photograph).

Seismic station at Three Sisters volcano in Central Oregon. Seismometer in box on the ground with data transmission antenna mounted on pole.

Columnar joints in horizontal orientation along the Ricksecker lava flow margin. Columns formed as lava cooled against valley filling glaciers leaving flows perched high on Mount Rainier's ridges.

Two prominent, historic lava flows are visible in this aerial photo of West Hawai‘i. Kīholo Bay is flanked by the 1859 Mauna Loa flow (left) and a Hualālai flow that  erupted around 1800 or earlier (right). These lava flows and other volcanic landscapes along Highways 11 and 190 will be the focus of a Volcano Awareness Month talk in Kona on Jan. 22

Photograph of Pingok Island, Alaska, reveals physical features of a changing Arctic: collapsing bluffs, salt-killed tundra (lighter brown near the bluff edge), and drained thermokarst lakes (rust-colored depressions).

An oblique aerial photograph shows the currently active Long Range Radar Site on Barter Island, formerly a DEW Line (Distant Early Warning) station that was deactivated in 1990. The Cold War-era landfill in the foreground of the photograph was at immediate risk from coastal erosion in 2006 and has since been relocated farther inland.

Photograph of barrier islands near the western terminus of Icy Reef located on the Beaufort Sea coast of Alaska, looking south. Egaksrak Lagoon separates the islands from the low-lying mainland coast of the Arctic National Wildlife Refuge and the Brooks Range in the background.
