Ringkasan
| Keterangan |
English: This image shows both the eruption plume and the heat signature of lava at the volcano’s summit and at nearby Fimmvörduháls, the site of a precursor eruption. The heat signature shows a rough estimate of temperature, with yellow being hottest and red coolest. The signature at Eyjafjallajökull is a concentrated circle without a river of lava, supporting the Icelandic Coast Guard’s observation that lava had not started to flow from the volcano. |

Image captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite. ASTER observed the heat signature by recording thermal infra-red radiation (energy) coming from the volcano. The rest of the image is made up of a combination of visible light and near infra-red light. The red that lines the top of the image is plant-covered land in the Markarfljót river valley. Blue streams of water flow from the Eyjafjallajökull ice cap to the river. Both north and due west of the Eyjafjallajökull volcano, the ice is pristine, but to the east and south, dark ash covers the snow. The white plume rising from the volcano is likely a mixture of steam and ash.
