Seismogenic lavas and explosive eruption forecasting

Nature, 2008
Volcanic dome-building episodes commonly exhibit acceleration in both effusive discharge rate and seismicity before explosive eruptions. This should enable the application of material failure forecasting methods to eruption forecasting. To date, such methods have been based exclusively on the seismicity of the country rock.

Explosive fragmentation of erupting magma

Nature, 1995
The magma responsible for explosive volcanic eruptions has both a volatile and an inert phase. Deep in the conduit of an active volcano, bubbles nucleate as the volatiles exsolve. As the magma rises, the bubbles grow through depressurization and continued exsolution.

Explosive Volcanic Eruptions

1984
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

Airborne Acoustics of Explosive Volcanic Eruptions

Journal of Computational Acoustics, 2001
A recently developed theoretical model of the airborne acoustic field from an explosive volcanic eruption of the Strombolian type is described in this article. The magma column is assumed to be a circular cylinder, which is open to the atmosphere at the top, and which opens into a large magma chamber below.
