Joint seismo-acoustic studies have huge
potential for improved understanding of eruption dynamics. These tools are even more powerful when
combined with other observational tools including: geodetic,
thermal imaging, gas flux monitoring, doppler radar, and
video. A recent field experiment at
Santiaguito Volcano in Guatemala (January 2007) led by UNH was
conducted in an attempt to integrate these diverse monitoring
techniques. Visit this website for more

At
this point an integrated seismo-acoustic-video approach is undertaken to
assess the following;
1)Relation
between pyroclastic emissions and elastic energy radiation. In other words, how
can we use seismic radiation to infer eruption intensity?
2)Fragmentation
location. How deep is an earthquake
occurring beneath the surface.
3)Physical
source mechanisms. What is the source
distribution in space and what physical motions are
responsible for elastic energy radiation.
