ABSTRACT The climactic June 15, 1991, eruption of Mount Pinatubo injected a minimum of
17 Mt (megatons) of SO 2 into the stratosphere--the largest stratospheric SO 2 cloud ever …

The abundance of volatile compounds, and particularly CO2, in the upper oceanic mantle
affects the style of volcanic eruptions. At mid-ocean ridges, eruptions are generally …

The explosive source mechanism, responsible for the volcanic activity of Stromboli, is
analyzed by seismic and infrasonic measurements in correlation with digitally processed …

During June 1999, we measured the amplitude and rate (number of events per second) at
which gas exited the vent at Stromboli volcano as discrete gas bursts or puffs. This allowed …

Crystal-rich materials (scoriae and lava flows) emitted during the 1985–2000 activity of
Stromboli were taken into consideration for systematic study of bulk rock/matrix glass …

The Etna 122 BC basaltic eruption had two Plinian phases, each preceded and followed by
weak phreatic and phreatomagmatic activity. This study infers changing eruption dynamics …

At Kilauea volcano, Hawaii, the recent long‐lived eruptions of Mauna Ulu and Pu'u O'o have
occurred in two major stages, defining a characteristic eruptive pattern. The first stage …

The character of the vesicle population in lava flows includes several measurable
parameters that may provide important constraints on lava flow dynamics and rheology …

Abstract Persistent activity at Masaya Volcano, Nicaragua, is characterised by cycles of
intense degassing, lava lake development and pit crater formation. It provides a useful site to …

Microtextural characteristics of fresh ejecta from Stromboli volcano were examined from
three periods of differing eruption style and intensity in 2002. Activity shifted from relatively …
