Structural stability of andesite volcanoes and lava domes
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2000Slope failures resulting from structural instability of andesitic volcanic edifices can generate mobile debris avalanches that travel long distances down or beyond the flanks of volcanoes. More than 20 major slope failures have occurred worldwide over the past 500 years, a rate exceeding that of caldera collapse.

Causes and consequences of pressurisation in lava dome eruptions
Earth and Planetary Science Letters, 1997Abstract High total and fluid pressures develop in the interior of high-viscosity lava domes and in the uppermost parts of the feeding conduit system as a consequence of degassing. Two effects are recognised and are modelled quantitatively. First, large increases in magma viscosity result from degassing during magma ascent.
