Dear Colleagues,



Please consider submitting your manuscript to the following special
session to be held at the 2009 Fall AGU meeting.  The abstract deadline
for electronic submission is September 3rd, 2009.



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, finement, and synthesis of
physical and numerical models for the observed changes.
