This view, looking northeast, shows the distal part of the flow, with the flow lobe behind Pahoa Marketplace to the right and the newer north-northeast advancing lobe to the left. The north-northeast lobe is following a drainage that leads to the steepest-descent path that crosses Highway 130 about 1 km (0.6 mi) south of the Maku‘u Farmer's Market.

This large-scale map shows the distal part of Kīlauea's active East Rift Zone lava flow in relation to nearby Puna communities. The area of the flow on December 30 at 2:30 PM is shown in pink, while widening and advancement of the flow as mapped on January 6 at 11:30 AM is shown in red.

This satellite image was captured on Sunday, January 4, by the Advanced Land Imager instrument onboard NASA's Earth Observing 1 satellite. The image is provided courtesy of NASA's Jet Propulsion Laboratory. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see.

Fractures define the perimeter of a new, smaller crater within Pu‘u ‘Ō‘ō. Light-colored areas are parts of the original cinder-and-spatter cone that have not been buried by lava flows. USGS photo.

Locations of the 97 beaches and barrier islands where our partners used the iPlover app to collect and record information on landcover characteristics at piping plover nesting locations during the breeding seasons of 2014-2016.

A peat auger core collected from the back-barrier marsh of Assateague Island, Maryland. An inorganic-rich layer found at the top of the core was delivered to the marsh via Hurricane Sandy. Visual contrast in sediment down-core reveal similar layers as that observed at the top of the core (i.e., Hurricane Sandy layer).

This compares a normal photograph of the active flow front with a thermal image. The photograph has been cropped and rotated to approximate the perspective of the thermal image. The thermal image shows that small breakouts were present immediately behind the leading tip of the flow and farther upslope, indicated by the white and yellowish pixels.
