Extension fractures in volcanic systems exist on all scales, from microscopic fractures to
large fissures. They play a fundamental role in the movement of fluids and distribution of …

We developed a technique for determining paleoeffusion rates and emplacement times for
submarine lava flows, using observations of flow morphology and estimates of eruption …

The growth of lava domes can be either quiescent or violent, with transitions between styles
of behavior commonly occurring with little warning. Here we propose that the behavior …

Eruption of the Soufrière Hills Volcano on Montserrat allowed the detailed documentation of
a Pélean dome-forming eruption. Dome growth between November 1995 and March 1998 …

Silicic volcanic activity has long been framed as either violently explosive or gently effusive.
However, recent observations demonstrate that explosive and effusive behavior can occur …

Scaling analyses describe the evolution of an extrusion of viscous or plastic fluid in the
presence of surface cooling and solidification, under the assumption that the flows consist of …

The 1986 eruption of B fissure at Izu-Oshima Volcano, Japan, produced, among other
products, one andesite and two basaltic andesite lava flows. Locally the three flows …

The morphologies of ridges and troughs on Earth and the processes involved in their
formation are reviewed for application to sets of subparallel ridges and troughs on outer …

Magmas erupted from Quaternary volcanoes of Southern Andes between 37° and 46° S
latitude are mainly basaltic to andesitic. However, PCCVC (40° S) shows a singular …
