Summary[edit]

Description
English: Nabro, a stratovolcano in the northeast African nation of Eritrea, rumbled to life late in the evening on June 12, 2011, following a series of earthquakes. The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite captured this natural-color image the next day.

Initial reports from news agencies and the Volcanic Ash Advisory Center in Toulouse, France, proclaimed the eruption to be occurring at Dubbi, a volcano further south. But later reports from volcanologists, field scientists, and the satellite image above appear to confirm the eruption at Nabro. There are no historical reports of eruptions at Nabro before today.

The volcano is part of a larger complex with several nested calderas nearby. It is part of the East African Rift, where the African continent is slowly pulling apart due to tectonic plate movements.
Deutsch: Nabro, ein Stratovulkan im ostafrikanischen Staat Eritrea, erwachte nach einer Erdbebenserie am Abend des 12. Juni 2011 aus seiner Untätigkeit. Das Moderate Resolution Imaging Spectroradiometer (MODIS) auf dem Aqua-Satellit nahm dieses Echtfarbenfotoam darauffolgenden Tag auf.

Die anfänglichen Berichte der Nachrichtenagenturen und des Volcanic Ash Advisory Center in Toulouse, Frankreich, erklärten die Eruption zunächst zum Dubbi gehörend, einem etwas weiter südlich gelegenen Vulkan. Doch spätere Berichte von Vulkanologen, Wissenschaftlern vor Ort und dieses Satellitenbild ergaben, daß es sich tatsächlich um eine Eruption am Nabro handelte. Es gibt keine historischen Beschreibungen über eines früheren Ausbruch dieses Vulkans.

Der Vulkan ist Teil eines größeren Kompexes mit mehreren benachbarten Calderen. Er ist Teil des Ostafrikanischen Grabensystems, wo der afrikanische Kontinent von tektonischen Plattenbewegungen langsam auseinandergetrennt wird.
