The molten lava that erupts from volcanoes comes from the mantle, the portion of the Earth that lies between the core in the center and the crust on top. It periodically pumps hot magma into a volcano’s magma chamber, filling it from below. Scientists believed that these pulses of magma mixed together in the chamber before climbing upward -- a process estimated to take several thousands of years. But Columbia University volcanologists found that the eruption...
