As previewed here (and at Eruptions) yesterday, the NASA Earth Observatory image of the day for 27 March 2010 is the ongoing fissure eruption at Eyjafjallajökull/Fimmvörduháls in south Iceland.
A commenter here asked about the green colour visible within the fissure and the drainage channel in this image. Robert Simmon of NASA answers that question in the Eruptions comments thread: ‘The green along the margin of the lava flow is an artifact of the satellite sensor. The true-color image is the combination of a 30m/pixel RGB image with a 10m/pixel panchromatic image. Each color pixels covers the same area as 9 panchromatic pixels, so you’ll occasionally get odd colors in high contrast areas’.
