Aerial view of Hilina fault system, Kilauea Volcano, Hawai`i

Aerial view of the southern coastline and part of the Hilina fault system of Kilauea Volcano between Keauhou Landing and Halape. Fortuitously, a detailed surveying network was installed from Mauna Loa to Kilauea's south flank in 1970 and reoccupied in the fall of 1974. With new measurements completed in the spring of 1976, scientists were able to calculate the horizontal movement that occurred in this area as a consequence of the earthquake on November 29, 1975. See map showing the interpretation of the horizontal displacements on Kilauea.

Much of Kilauea Volcano moved seaward (southeastward) during the earthquake. Between the caldera and southern shore, the pattern of movement generally increases seaward and converges toward the area of maximum subsidence between Halape and Keauhou Landing (shoreline in upper right).
