WebIf there is not enough magma or enough pressure to create an explosive eruption, the magma may form a lava dome. Because it is so thick, the lava does not flow far from the vent. (Figure 2). WebIf a magma has low viscosity (it is runny), gas can escape easily, so when the magma erupts at the surface it forms lava flows. These eruptions are (relatively!) gentle, effusive eruptions. If a magma rises very slowly within the conduit. or throat, of the volcano, all the gas can escape. When the magma is viscous (or sticky), it can’t flow ...
