Lava Flows from Kilauea Volcano, Hawaii

Kilauea volcano, Hawaii, has been in continuous eruption since 1983. Recently, lava flows from a vent close to the Pu'u O'o cone began cutting through dense vegetation and moving closer to inhabited areas. On September 8, 2014, the Advanced Land Imager (ALI) on NASA's Earth Observing 1 spacecraft obtained this infrared image. Although there are clouds and smoke from burning vegetation, a line of red points delineate the path taken by the new lava flows. As always, the threat posed by these lava flows is being assessed and monitored by scientists at the United States Geological Survey Hawaiian Volcanoes Observatory.

Holuhraun, Iceland Volcanic Lava Flows (6 September 2014)

On the night of September 6, 2014, the Advanced Land Imager (ALI) on NASA's Earth Observing 1 (EO-1) spacecraft observed the ongoing eruption at Holuhraun, Iceland, from an altitude of 438 miles (705 kilometers). Data were collected at a resolution of 98 feet (30 meters) per pixel at different visible and infrared wavelengths.

Although partially covered by clouds, this scene shows the extent of the lava flows that have been erupting from a long fissure over the last week. The front of the lava flows are to the right (east) and extend more than 6.3 miles (10 kilometers) from the vent. The intense radiant energy from the incandescent lava illuminates the clouds and plume from the vent to create this ethereal scene.

The ongoing eruption is being closely monitored by scientists at the Icelandic Meteorological Office and the University of Iceland.

Holuhraun, Iceland Volcanic Eruption

On the night of September 1, 2014, the Advanced Land Imager (ALI) on NASA's Earth Observing 1 (EO-1) spacecraft observed the ongoing eruption at Holuhraun, Iceland, from an altitude of 438 miles (705 kilometers). Data were collected at a resolution of 98 feet (30 meters) per pixel at different infrared wavelengths and were then combined to create this false-color image that emphasizes the hottest areas of the vent and resulting lava flows. The image captured the 0.6-mile (1-kilometer)-long fissure from which lava is erupting, a channeled lava flow, and a broad expanse of lava flows extending 2.2 miles( 3.5 kilometers) from the fissure.

The eruption is being closely monitored by scientists at the Icelandic Meteorological Office and University of Iceland. Because this event took place away from the icecaps of Vatnajökull and Dyngjujökull, this event did not generate a large ash plume like that of the Eyjafjallajöull eruption in Iceland in 2010.
