Setting up GPS receivers on the 1970's lava flows near Kilauea Volcano.
Hawaii Volcanoes National Park is best known for its beautiful volcanic landscapes, but it is also the site of several major faults that have produced large earthquakes in the past, including the 1975 Kalapana earthquake. Earthquakes like this could pose a significant tsunami hazard in both hawaii and beyond. Detecting future motion of the Hilina faults will be difficult due to few permanent GPS stations in the area. We have installed a network of 18 new monuments in the area to assist with future surveys of fault slip associated with the Hilina fault system. By surveying this network every few years, we will be able to 1) determine if the Hilina faults are inactive as Delaney et al. (1998) conclude, and 2) survey the network immediately after a slip event to determine displacement along and across the Hilina fault system. We hope that the
displacements will help us better understand the fault geometry, slip patterns, and seismic hazards associated with the Hilina fault system.
