One of the biggest challenges in volcanic hazard assessment is to understand how and why
eruptive style changes within the same eruptive period or even from one eruption to the next …

With the emergence of portable broadband seismic instrumentation, availability of digital
networks with wide dynamic range, and development of new powerful analysis techniques …

Languages, like genes, provide vital clues about human history,. The origin of the Indo-
European language family is “the most intensively studied, yet still most recalcitrant, problem …

The style and evolution of volcanic eruptions are dictated by the fluid mechanics governing
magma ascent. Decompression during ascent causes dissolved volatile species, such as …

Over the past 25 years, our understanding of the physical processes that drive volcanic
eruptions has increased enormously thanks to major advances in computational and …

The fragmentation of magma, containing abundant gas bubbles, is thought to be the defining
characteristic of explosive eruptions,,. When viscous stresses associated with the growth of …

Kimberlite volcanism involves the ascent of low viscosity (0.1 to 1 Pa s) and volatile-rich
(CO2 and H2O) ultrabasic magmas from depths of 150 km or greater. Theoretical models …

Most studies of thermally induced cracking in rocks have focused on the generation of
cracks formed during heating and thermal expansion. Both the nature and the mechanism of …

Rhyolite magma has fuelled some of the Earth's largest explosive volcanic eruptions. Our
understanding of these events is incomplete, however, owing to the previous lack of directly …

Magma fragmentation is the breakup of a continuous volume of molten rock into discrete
pieces, called pyroclasts. Because magma contains bubbles of compressible magmatic …
