AGU Session V32: Volcanic Dynamics: Temporal Changes of Physical Properties
at Volcanoes With and Without Surficial Activity
From: Martha Savage <Martha.Savage@xxxxxxxxx>
*********************************************************************************************************
Dear Colleagues,
We would like to remind you of the upcoming deadline for abstracts to be
submitted the AGU special session V32: Volcanic Dynamics: Temporal Changes
of Physical Properties at Volcanoes With and Without Surficial Activity to
be held at the 2009 Fall AGU meeting. The abstract deadline for electronic
submission is September 3rd, 2009.
The following invited speakers will give talks with indicative titles below:
Joachim Gottsmann: The forensics of sub-surface processes on island
volcanoes from integrated geodetic observations: results from Tenerife and
Montserrat
Andre Revil: Using geoelectrical signals to monitor ground water flow in
geothermal systems and active volcanoes
Florent Brenguier: Using seismic noise to monitor volcanic activity
Yosuke Aoki: Geophysical monitoring of Mt. Asama, Japan, during the 2008-9
eruptions
Here is a description of the session:
One of the main goals of current volcanological research is the
identification of reliable precursors to the onset of eruptions, or to
changes in an ongoing eruption. While many eruptions are preceded by
increases in the rate or intensity of commonly-monitored signals, sometimes
eruption onsets are not preceded by obvious changes with adequate warning
times (e.g., Ruapehu 1995, Hekla 2000, Okmok 2008). Furthermore, few
reliable precursors to co-eruptive changes (such as an increase in effusion
rate or explosivity) have been identified, and some observed changes at
volcanoes are not associated with eruptions. Thus, new approaches to
detecting and understanding the significance of subtle signals of magma
ascent may provide important additions to the current set of tools for
eruption forecasting. We seek studies that present new observations and/or
models of dynamic processes coincident with or independent of eruptions that
provide insight into volcano behavior, including but not limited to temporal
changes in seismicity patterns or characteristics (e.g., changes in seismic
velocities or source mechanisms), gas emissions, surface deformation,
temperature, microgravity, self-potential, magnetotellurics, and volcano
hydrology. A second goal is to encourage discussion, refinement, and
synthesis of physical and numerical models for the observed changes.
Convenors: Diana Roman, Martha K. Savage, Matthew E. Pritchard, and Matthew
