WebMar 1, 1998 · An eruption occurs when magma moves upwards and along the segment through a dike or vertical crack, intersects the seafloor, and flows onto the surface through a fissure. We know the characteristics of fissure eruptions on land, and envision that the same processes are at work on the seafloor. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals. It also contains small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur.
