Eruption at Nabro Volcano
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
The remote Nabro Volcano, along the border between Eritrea and Ethiopia, emitted a thick plume of volcanic gases on June 15, 2011. The Toulousse Volcanic Ash Advisory Center and the Joint Air Force & Army Weather Information Network reported that the plume rose to an altitude of 35,000 feet (11,000 meters), and consisted mainly of sulfur dioxide. The bright white color of the plume suggests it contains a high concentration of water vapor as well.
