Quizplus · Accepted Answer

The viscosity (how thick or runny the magma is) and gas content (amount of gas dissolved in the magma) are the two main factors that determine whether a volcano eruption will be explosive or non-explosive. High viscosity magma with a high gas content is more likely to produce an explosive eruption, while low viscosity magma with a low gas content is more likely to produce a non-explosive eruption.
