Pinpointing Where Volcanic Eruptions Could Strike

Scientists from all over the world gathered and investigated on how to know when volcano’s around the world will erupt. By studying a rare sequence of 13 magmatic events where hot molten rock was intruded into a crack between the African and Arabian plates they found that the location of each intrusion was not random. They showed that they were linked because each event changed the amount of tension in the earth's crust. The information that they found will help them to more accurately predict where and when the volcanos will erupt. The team studied the region around the volcano which erupted in 2005 because a vertical crack which is created when Magma seeps from underground through rifts in the surface of the earth. Magma hot molten rock was injected along the dyke between depths of 2 and 9 km, and altered the tension of the earth. The team was able to watch the 12 smaller dykes that subsequently took place in the same region over a four year period.
