HIGP Earthquake Seismology Mission To perform
excellent research in the field of earthquake
seismology Include studies relevant to the
State of Hawaii, where there are high earthquake,
tsunami, and volcano hazards and a wealth of
interesting seismological problems Secure
funding, publish papers, train students and
postdocs, teach courses, conduct education and
outreach (such as interviews with the press and
testimony at the legislature after the Mw 6.7
Kiholo Bay earthquake) Develop important
collaborations and interactions the USGS
Hawaiian Volcano Observatory, the Pacific Tsunami
Warning Center, the Hawaii Integrated Seismic
Network, as well as national and international
collaborations

PersonnelCecily J. Wolfe, hired
8/2000Carolina Anchieta (graduate
student)Undergraduate RAs Also collaborations
with scientists at USGS HVO, Carnegie Institution
of Washington, Scripps Institution of
Oceanography, Woods Hole Oceanographic
Institution, Yale, Stanford, U. WisconsinNew
collaborator Takuji Yamada, a research Fellow
at HVO starting May 2008, funded by Japan JSPS
proposal written with help from Cecily Wolfe and
Paul Okubo
3
Funded research projects PLUME a 2.5 million
NSF-funded project (split among several
institutions and ocean bottom seismometer
deployment costs). Cecily Wolfe is the lead PI
on upper mantle body wave tomography and
Hawaiian earthquakes and a collaborator on
surface wave studies, shear-wave splitting, and
receiver function work. Slow earthquakes and
triggered seismicity 50K NSF SGER (split among
2 institutions) and USGS support to conduct a
seismic and geodetic experiment in 2007, which
was successful in recording a dike-triggered slow
earthquake. An NSF grant for analyses with
student or postdoc support is pending. Studies
remaining from expired NSF EAR grant on Hawaiian
earthquakes. Mauna Loa deep long period
earthquake swarm 2,000 long-period earthquakes
at 45 km depth, associated with the 2002-2005
intrusion. Kiholo Bay earthquake aftershocks.

Examples of major new results
Figure from article on the PLUME Experiment,
Nature, 2003
Configuration of 2 PLUME deployments
5
Hawaiian earthquakes, 1861-2005, showing that
some large damaging earthquakes occur outside of
the Big Island, an area that is not well
monitored by the USGS HVO
6
New PLUME results from finite frequency S wave
tomography beneath the Hawaiian Islands1st
PLUME deployment data only 2nd PLUME deployment
data will help extend image deeperThis PLUME
study has already been solicited for submission
by Brooks Hanson, Deputy Editor for Physical
Sciences at Science Magazine
7
PLUME analyses discover new seismically active
fault zones beneath Maui, Molokai, and near Oahu
New earthquakes on PLUME
HVO located earthquakes on PLUME
8
Future directions PLUME follow-on and geodynamics
proposal (PLUME PIs, Garrett Ito/Dave
Bercovici) Ocean observing with PLUME data USGS
Earthquake Hazards external grant program (but
only funds small grants, typically 1 year at
60K) HVO/UH Manoa cooperative agreement
