Satellite view of activity at summit and ERZ

Detailed Description

This image was captured on Friday, August 9, by the Advanced Land Imager sensor aboard NASA's Earth Observing 1 satellite, and shows Kīlauea volcano from the summit down the east rift zone. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures, and show active lava. Two areas are active on Kīlauea. At the summit, a circulating lava lake in Halema‘uma‘u crater produces the bright pixels at the left edge of the image. Along the east rift zone, the ongoing Pu‘u ‘Ō‘ō eruption is now feeding two lava flows. The Peace Day flow has active surface flows on the coastal plain and an active ocean entry, just west of Kalapana village, while the Kahauale‘a 2 flow is active at the forest boundary north of Pu‘u ‘Ō‘ō. Satellite images such as this help fill in observational gaps between field visits.
