- Descr: A preliminary deployment of PASSCAL seismographs at Merapi
in 1998 yielded a remarkable data set of volcanic earthquakes associated
with dome growth, including very long period (VLP) signals superposed
on dome related shallow seismic events. The proposed project aims at
resolving the source mechanisms for these events, via a more comprehensive
PASSCAL deployment of broadband seismographs in 2001 in order to experimentally
test hypotheses developed on the basis of preliminary data. The results
of this study will have important implications in interpreting broadband
signals associated with volcanic processes, and may lead to a fundamentally
new understanding of seismicity associated with hazardous dome growth.
