Fall AGU Session: Potential Field Investigations of Active Volcanic Systems
**********************************************************
From: Michael P Poland <mpoland@xxxxxxxx>
We would like to encourage abstract submissions for the following
session at the Fall AGU meeting focused on potential measurements (e.g.,
gravity, magnetics) at active volcanoes. The abstract deadline is
September 7.
V07: Potential Field Investigations of Active Volcanic Systems
The use of potential field methods (for example, gravity and
electromagnetic surveys) in the monitoring and investigation of active
volcanoes can provide a wealth of information on subsurface magmatic
processes. For example, geodesy alone cannot discriminate between magma
and aqueous fluid intrusion at large quaternary silicic calderas.
Gravity measurements, however, can constrain the mass of the intrusion,
and when combined with surface displacement data, can be used to infer
the density of the intrusive fluids. Potential measurements may also be
used to infer sub-volcanic structure, and are useful in tracking the
evolution of active volcanic system over time.
This session seeks to highlight the broad range of potential field
methods applied to volcanoes, including the joint analysis of potential
field and geodetic data. This includes theoretical, field-based,
technology development, and modeling studies. We hope to stimulate
additional discussion and interest in potential field measurements, and
motivate greater use of these methods in the study of active volcanic
systems.
