A Kknematic model for ground deformation at Kilauea volcano during 1992-2005

Kilauea volcano is actively deforming at rates of up to 10 cm/yr. Existing models for Kilauea well explain the ground deformation of the east rift zone and along the southflank. InSAR data for the 1992-2005 period (derived from Jers and Radarsat satellites) clearly show significant subsidence at rates of 5 cm/yr and more in the southwest rift zone. We present a kinematic model to explain the observed deformation consisting of deep rift intrusion and gravitationally-driven normal faulting in the southwest rift zone area.
