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 …

As key flow properties for coalbed methane production, greenhouse gas reduction through
CO 2 storage in coal and gas drainage to improve mining safety, knowledge of gas diffusion …

Most volcanoes erupt both effusively and explosively, with explosive behaviour being
responsible for most human fatalities. Eruption style is thought to be strongly controlled by …

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

Jets, ie collimated streams of matter, occur from the microscale up to the large-scale
structure of the universe. Our focus will be mostly on surface tension effects, which result …

Ignimbrites are vast, landscape-modifying deposits composed mainly of pumice fragments
and ash. They derive from the most. hazardous types of explosive volcanic eruptions and …

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 …

Fragmentation phenomena are reviewed with a particular emphasis on processes that give
rise to drops—in the broad sense, the process of atomization. Various observations are …

Explosive eruptions are the most powerful and destructive type of volcanic activity. These
eruptions are characterized by magma fragmentation, the process through which a bubbly or …

Volcanic eruptions can be either slow outpourings of lava or explosive ejections of
fragmented rock. In his Perspective, Dingwell discusses the physical and chemical …
