Kilauea
Deformation: I am studying the time dependent deformation of Hawaiian
volcanoes using mostly GPS and some InSAR. The June 2007 intrusion of
Kilauea was monitored in unprecedented detail by the continuous GPS network
on Kilauea, as well as tiltmeters, and the ALOS and EnviSat radar
satellites.
Kilauea
Volcanic Transient: We studied a volcanic transient following the 1997
intrusion at Napau Crater on Kilauea volcano (See Desmarais(2005) above)
using the Kalman Filter based Extended Network Inversion Filter (ENIF)
(McGuire et al., 2003) to incorporate data as well as a priori information
about the initial state of a system and the shape of the model. The
ENIF is also capable of making forward predictions, which we hope may help
in predicting eruptions.
Mauna
Loa Inflation Models: I am also working on some models of a summit
inflation of Mauna Loa.
Kilauea
Slow Earthquakes: In 2000 there was a slow earthquake on Kilauea volcano in which the south flank moved 6cm
seaward. It's magnitude was equivalent to a M5.7 occurring over 36
hours. Since observing that event, we've recognized three more
similar events (1998, 2000, 2003, 2005) that occur in the same
location. I am working on modeling the time evolution of these
events, and their associated stressing history.
