The Earth Observing-1 (EO-1) satellite was orbiting at an altitude of about 700 kilometers (400 miles) when it captured our April 11 Image of the Day — a nadir view of Kilauea’s Kahaualeʻa 2 lava flow creeping through forests northeast of Pu’u ’O’o crater. Much closer to the surface, the U.S. Geological Survey monitors the lava flow with helicopter overflights.
The image below shows a portion of the flow as it appeared on March 7, 2014. The smoke near the flow front is caused by lava burning trees and other vegetation in ohia lehua forests. Gases emanating from the vent are visible on the upper left.
