Frequent question: Why are there volcanoes in East Africa?

This process of continental breakup is strongly associated with volcanoes because, as the land splits, molten rock rises into the Earth’s crust. Some of this magma makes it to the surface and forms volcanoes. Most of East Africa’s volcanoes are currently dormant. But they could erupt in the future.

Which volcano erupts the coldest lava on Earth?

Because of its very unusual composition, carbonatite is literally the coolest lava on earth, erupting at 500-600 degrees Centigrade (930-1,100 degrees F), compared with 1,160 degrees C (2,120 degrees F) for lava from Kilauea’s current eruption.
