Volcanic activity takes many forms, ranging from quiet lava emissions to extremely violent and explosive bursts, many of which can be related to magma composition as discussed in Chapter 3. The kinds of eruptions can be correlated to volcano shapes and sizes, and in this chapter we explore the connection between pyroclastic systems, eruptive mechanisms

Neurospora following a Volcanic Eruption
Nature, 1952EARLY in 1951, Mount Lamington in New Guinea erupted violently, and the resulting shower of hot ashes which followed the explosion devastated many miles of the countryside, causing severe damage and loss of life. Very soon after the eruption, Mr. G. A.

In recent years, some major volcanic eruptions have been forecast successfully, but others have claimed many lives. In his Perspective, Scarpa charts recent efforts to improve predictions of volcanic eruptions. Broadband seismic studies, such as those of Kumagai et al., are a powerful tool for modeling the magma dynamics.

During explosive volcanic eruptions, up to 1014 kg of volcanic ash may be erupted from a vent forming violent ash flows or towering eruption columns. This massive amount of material is subsequently deposited on the ground, with much of the coarser fraction of the flow being deposited within a few hundred kilometres of the volcanic edifice.
