Benjamin A. Brooks, James Foster, David Sandwell, Cecily J. Wolfe, Paul G. Okubo, Michael P. Poland, David Myer
2008, Science (321) 1177
We demonstrate that a recent dike intrusion probably triggered a slow fault-slip event (SSE) on Kilauea volcano's mobile south flank. Our analysis combined models of Advanced Land Observing Satellite interferometric dike-intrusion displacement maps with continuous Global Positioning System (GPS) displacement vectors to show that deformation nearly identical to four previous...
