| Synopsis | General: Hualalai Volcano, the oldest of the three active volcanoes on Hawai'i, has three poorly defined volcanic lineaments inferred along broad topographic ridges, the northwest [2602a], north [2602b], and south-southeast [2602c] volcanic lineaments. Other researchers, including Moore and others (1987 #6962) and Kauahikaua and others (2002 #6947), use the term "rift zone" rather than "volcanic lineament." The rift zones in Moore and others (1987 #6962) appear to radiate from a central point approximately 5 km east of the summit of Hainoa Crater. Holcomb and others (2000 #6945) offer alternative rift zone models. Offshore, the North Kona slump is located on the western flanks of Hualalai and Mauna Loa Volcanoes (Moore and Chadwick, 1995 #6959). The landslide head may correspond with the northwest rift zone on Hualalai (Moore and Chadwick, 1995 #6959). Sections: This fault has 3 sections. The sections are the northwest [2602a], north [2602b], and south-southeast [2602c] volcanic lineaments. |
