Session Description:
The 1991 eruption of Pinatubo Volcano in the Philippines was one of the
largest volcanic eruptions of the 20th Century and spawned research in
many disciplines.For example, in the 25 years since the eruption,
volcanologists substantially improved understanding of how strain,
magmatic gases, and groundwater produce the distinctive patterns of
unrest that foretold Pinatubo’s eruption.Atmospheric scientists
discovered that winter warming (a forced positive mode of the Arctic
Oscillation) follows large, sulfate-rich tropical explosive eruptions,
that volcanic eruptions increase the probability of an El Niño in the
following year and affect the Atlantic Multidecadal Oscillation, and
they have quantified the effects of volcanic aerosols on ozone
depletion.On its 25th anniversary, we invite papers that emphasize new
insights arising from the Pinatubo eruption and its aftermath, in
volcanology, volcano-seismology, geochemistry, fluvial and watershed
processes, plume transport, effects on ozone, radiative forcing, and
climate response.
