The 2011 Nabro eruption was an eruption of the Nabro stratovolcano in the Southern Red Sea Region of Eritrea, which began on 12 June 2011 after a series of earthquakes. The eruption killed seven〔 and possibly a further 31 people〔 and is estimated to be the highest altitude injection of sulfur dioxide (SO2) ever observed by satellite. The Mount Pinatubo eruption 20 years earlier emitted ten times more SO2.〔(【引用サイトリンク】title=A-train observations of Nabro (Eritrea) eruption )〕 The ash cloud from the eruption reached altitudes which disrupted airline traffic in the region.〔 Until the eruption began, the volcano had no records of historical eruptions.〔 ==Gallery== Image:Nabro Volcano ash cloud 2011-06-13, Eritrea.jpg|Satellite image of Ethiopia/ Eritrea showing the ash plume from Nabro on 13 June 2011.
