A volcano erupts in the Red Sea On Sunday, the Yemeni island of Jabal al-Tair was rocked by an explosion. A column of flame, ash and smoke appeared above the 1200-meter mountain, rising 300 meters, and streams of hot lava rushed down the slopes. In principle, this all looks completely ordinary: an average, not particularly high volcano, not a very strong eruption, and the picture of the natural phenomenon itself is very standard, you could even put it in textbooks.
