| Synopsis | General: Kilauea Volcano is the youngest subaerial volcano in Hawai'i. Kilauea's extensional structures include Kilauea's caldera [2608a], the east rift zone [2608b], and the southwest rift zone [2608c]. Two additional fault systems are located to the southeast of Kilauea's caldera: the Koa'e fault system [2609], and the Hilina fault system [2610]. The Koa'e and Hilina fault systems are assigned their own fault numbers rather than grouping these faults into a single extensional feature for Kilauea. Another categorization scheme by Delaney and others (1998 #6939) subdivides Kilauea Volcano into four geographic regions: (1) western south flank and lower southwest rift zone, (2) summit and upper rift zones, (3) middle east rift zone, and (4) central and eastern south flank.
Along the coast and offshore of Kilauea's south flank to the southeast, the Hilina fault system [2610] may define the headscarps to the submarine Hilina slump and subsequent Papa'u sand-rubble flow (see Moore and others, 1989 #6961; Moore and Chadwick, 1995 #6959). Sections: This fault has 3 sections. The sections designated for Kilauea Volcano are Kilauea's caldera [2608a], the east rift zone [2608b], and the southwest rift zone [2608c]. |
