Where is the fault line for Hawaii located?
Koa'e Fault Zone
Fault Scarpes in the Koa’e Fault Zone create a Horst and Graben type of terrain. Some of the scarpes (called “pali” in native Hawaiian) face northwards, towards the summit of Kilauea Volcano and Halemaumau Crater. This is unusual because the scarpes usually face in the direction of flow. Monitoring data of the fault zone has revealed that at the Pacific Ocean, the land mass is moving at a rate of 2.5 centimeters per year. In the upper regions of the fault zone, the crust is moving at a rate of 8cm annually. This vast difference in movement rates has over time created numerous antiforms in the region.
