Limestone-bearing gravel, the newly named Hulopoe Gravel, blankets the coastal slopes on Lanai. The deposit, which reaches a maximum altitude of 326 meters, formerly was believed to have been deposited along several different ancient marine strandlines, but dated submerged coral reefs and tide-gauge measurements indicate that the southeastern Hawaiian Islands sink so fast that former worldwide high stands of the sea now lie beneath local sea level. Evidence indicates that the Hulopoe Gravel and… Expand
Megatsunami deposits on Kohala volcano, Hawaii, from flank collapse of Mauna Loa
The origin of coastal and high-elevation marine gravels on the Hawaiian islands of Lanai and Molokai is controversial, because the vertical tectonics of these islands is poorly constrained. TheExpand
Competing mechanisms for boulder deposition on the southeast Australian coast
This study investigates the role of late Holocene sea-level change, large storms and possible pre-historic tsunami in the deposition of boulder features on an exposed headland and sheltered rockExpand
Uplift caused by lithospheric flexure in the Hawaiian Archipelago as revealed by elevated coral deposits
The presence of definitive indicators of sea level such as corals found in growth position, coralline beach deposits, wave-cut notches and wave-eroded terraces, all at elevations above known levelsExpand
Catastrophic collapse of the volcanic island of Hierro 15 ka ago and the history of landslides in the Canary Islands
Landslides play an important role in the evolution of many volcanic islands, producing huge fields of blocky volcanic debris on their submarine slopes. Sidescan sonar images presented in this paperExpand
Boulder Deposits from Large Waves during the Last Interglaciation on North Eleuthera Island, Bahamas
Abstract Seven boulders measuring 100 to 1000 m 3 are scattered along the coastal ridge of north Eleuthera. Some are situated on ridge crests up to 20 m above present sea level. The boulders wereExpand
Support for the Giant Wave Hypothesis: evidence from submerged terraces off Lanai, Hawaii
The origin of subaerial coral conglomerate deposits on the Hawaiian islands of Lanai and Molokai is controversial, primarily because these deposits are difficult to interpret and the vertical motionExpand
The ancient shorelines of Lanai, Hawaii, revisited
Abstract Three ancient shorelines (the Mahana, Kaluakapo and Manele) have been described at elevations of 365, 190 and 170 m in the Kaluakapo Crater, Lanai, Hawaii [Bernice P. Bishop Mus. Bull. 237Expand
Giant landslides, mega-tsunamis, and paleo-sea level in the Hawaiian Islands
Abstract Landslide tsunami simulations have advanced to the point where the tsunamigenic potential of giant submarine landslides (GSL) can be affirmed, while the subsidence history of differentExpand
Flank collapse and large-scale landsliding in the Cape Verde Islands, off West Africa
Large-scale landslides occur on the flanks of many volcanic oceanic islands worldwide. None have taken place in historical time, but their geohazard potential, especially their ability to generateExpand
Fossiliferous Lana'i deposits formed by multiple events rather than a single giant tsunami
It is shown that the Hulopoe gravel was formed by multiple depositional events, separated by considerable periods of time, thus invalidating the main premise of the ‘giant wave’ hypothesis. Expand


Ancient shore lines on the Island of Lanai, Hawaii
INTRODUCTION The island of Lanai, Hawaii, lies 59 miles southeast of Honolulu, Oahu, and 9 miles west of Lahaina, Maui. Its maximum north-south length is l3¼ miles, its east-west length 13 miles, andExpand
A contribution to the geochronology and petrology of the island of Lanai, Hawaii
Chemical analyses of four lava flows from Lanai, Hawaii confirm petrographic observations that the flows of Lanai are typical Hawaiian tholeiites, somewhat more similar in composition to those ofExpand
Drowned Reefs as Indicators of the Rate of Subsidence of the Island of Hawaii
A major submerged terrace whose seaward edge is at about 150 m depth was investigated in 1983 during 10 dives with the Hawaii Undersea Research Laboratory (HURL) submersible Makali'i off KealakekuaExpand
Potassium-Argon Ages of Lavas from the Hawi and Pololu Volcanic Series, Kohala Volcano, Hawaii
Kohala is regarded as the oldest major shield volcano on the island of Hawaii. Potassium-argon ages of nine lava flows from the predominantly tholeiitic Pololu Volcanic Series of Kohala Volcano rangeExpand
