MODIS Aqua 1 km true color satellite image showing resuspended volcanic ash cloud (arrow) generated from high winds scouring exposed ash on the Pacific side of the Katmai volcanic range. The cloud stretches across the Shelikof Straight and western Kodiak Island. Image ID 2010333 taken November 29, 2010. Courtesy NASA.

This MODIS Aqua 1-km-resolution, true-color satellite image shows a resuspended ash cloud generated from high winds scouring the dry, unvegetated deposits in the Valley of Ten Thousand Smokes. The cloud stretches across Shelikof Strait to western Kodiak Island.

Location: south-central Alaska, from Kodiak to Anchorage

Geologist changing the data card in a time-lapse camera on the western rim of Pu'u 'O 'o. The lack of trade winds allowed for a clear view into the crater.

A similar wide shot of the flow field, incorporating more of the coastline west of the ocean entry. Hilina Pali is the cliff face in the background. Small lava channels enter the ocean along a section of the Puhi-o-Kalaikini lava delta.

This overlay of a photograph, and a thermal image of the same area, highlights several active breakouts on the coastal plain. Comparing today's image to the composite taken on Oct 28, the breakouts are new, but most of the other features are unchanged.

Looking into the Halema'uma'u Overlook vent during a lava high stand. In the lower half of the vent, several glowing cracks in the crusted lava surface can be seen through the diffuse fume. The remaining portion of the Halema'uma'u Overlook fence is at the bottom of the photograph.

Sulfur dioxide gas emissions from the crater of Pu‘u ‘Ō ‘ō on Kīlauea’s east rift zone and the vent within Halema‘uma‘u Crater at Kīlauea’s summit create volcanic pollution that affects the air quality of downwind communities.  Here, a USGS Hawaiian Volcano Observatory gas geochemist measures Pu‘u ‘Ō‘ō gas emissions using an instrument that detects ga

An aerial view of Pu'u 'O 'o, looking toward the southwest. Although the inside of the crater is shrouded in fume, a distinct plume can still be seen coming from the east wall. This vent has once again become the dominant heat source in Pu'u 'O 'o since the cessation of flows in the crater several weeks ago.

Loss of glaciers and snowpack due to climate warming in alpine regions is putting pressure on a rare aquatic insect, the meltwater stonefly, according to a U.S. Geological Survey study.
