Residents woke to find their homes covered with a film of grey black ash, 1mm to 2mm thick. The source is the Debbi volcano, which began erupting on Sunday night for the first time since 1861. The volcano is situated in the remote Southern Red Sea Region of Eritrea, a thinly populated area. But the French weather bureau is predicting that by Tuesday the cloud could spread as far as Egypt, Sudan and even Israel.

居民醒来后发现他们的家里被1到2毫米的灰黑色的火山灰所覆盖。这些火山灰源自杜比火山（Debbi volcano）。杜比火山在周日晚上喷发，这是自1861年以来，首次喷发。该火山位于红海南部偏远的厄立特里亚地区，这里的人口非常的稀少。但是，法国气象局的预测，火山灰将在周二蔓延至埃及，苏丹，甚至以色列。
