Kinematic GPS at Kilauea Volcano
Kilauea Volcano, on the island of Hawaii,
presents a major seismic as well as volcanic hazard.
Hawaiian volcanoes have also generated
mega-landslides and tsunamis in
the geologic past, and Kilauea's south flank is
considered the most likely site of such
a catastrophe in the future. Frequent deformation
monitoring is needed to understand south flank instability
and to provide short term hazard assessments. Stanford University,
in collaboration with the USGS Hawaiian Volcano Observatory
(HVO), has installed a continuously operating GPS network
on Kilauea for this purpose. This
network has generally estimated daily position estimates
from 2-10 days after the data are collected.
In the past two years we have worked to extend this network
into a real-time deformation system. The paper listed below describes
filtering techniques that will be used in the network analysis.
Future work will discuss event detection and real-time modeling.
