“…Previous studies have shown that there are also submerged reefs in many tropical island surroundings and continental shelves, such as the Caribbean Sea (Macintyre,1972;Lighty et al, 1978;Fairbanks, 1989;Hubbard et al, 1990;Blanchon et al, 2002;Jarrett et al, 2005), the Seychelles Islands (Stoddart, 1971), Madagascar (Pichon, 1977;Guilcher, 1988), the Bahamas Islands (Hine and Steinmetz, 1984), the edge of the western Indian continental shelf (Wagle et al, 1994;Colonna et al, 1996;Vora et al, 1996;Dullo et al, 1998;Rao et al, 2003) in the Indian Ocean, Papua New Guinea (Guilcher, 1988;Galewsky et al, 1996), the Fiji Islands (Guilcher, 1988), the Hawaiian Islands (Veeh, 1966;Ku et al, 1974;Szabo et al, 1994;Muhs and Szabo, 1994;Muhs, 2002;Webster et al, 2004Webster et al, , 2010Hearty et al, 2007), the outer edge of the Florida continental shelf (Lighty, 1977), and the Gulf of Carpentaria (Harris et al, 2004) and the outer edge of the Great Barrier Reef (GBR) (Veeh and Veevers, 1970;Harris and Davies, 1989) in Australia in the Pacific Ocean. These submerged reefs in the continental shelves, such as the 1300 km-long submerged reefs distributed on the outer edge of the western Indian continental shelf (Vora et al, 1996), were mainly formed during the last glacial period, whereas the submerged reefs around oceanic volcanic islands, such as the Hawaiian Island of Lanai (Webster et al, 2010), have longer formation histories Compared with modern coral reefs, submerged coral reefs not only reflect the shelf ...…”

“… Faichney et al [2009] examined regional and high‐resolution bathymetry data of the central MNC to map the terrace distribution and morphology around the Lanai region of the MNC. Many of these terraces have been sampled and observed and are drowned reefs [ Faichney et al , 2009; Webster et al , 2006, 2010; I. D. E. Faichney et al, The impact of the Mid‐Pleistocene Transition on the composition of submerged reefs of the Maui‐Nui Complex, Hawaii, submitted to Palaeogeography , Palaeclimatology , Palaeoecology , 2010]. For the purposes of this study we assume that all the terraces are submerged reefs that grew horizontally at sea level, however as some may be lava shorelines or associated with landslide morphologies, we will refer to them all as terraces.…”

“…For the purposes of this study we assume that all the terraces are submerged reefs that grew horizontally at sea level, however as some may be lava shorelines or associated with landslide morphologies, we will refer to them all as terraces. We use the bathymetric data set described by Faichney et al [2009] and Webster et al [2010] but also present and analyze a newly compiled data set from the entire MNC, including Oahu (Figure 1). The integrated data set was gridded at 30 m resolution and these grids were imported into both ArcGIS 9.2 and Fledermaus 6.7 to map and correlate the distribution of the terraces.…”

“… Campbell [1986] identified submerged terraces off Lanai and calculated a subsidence of 1.9 m/kyr for Lanai and 2.4 m/kyr for Hawaii. Campbell also incorrectly correlated by depth the submerged terraces off Lanai with those off Hawaii [ Webster et al , 2010] and suggested that the difference in subsidence rates was due to volcanic loading of Hawaii. Moore and Campbell [1987] projected the breaks in slope of the Lanai and Hawaii terraces onto a northwest‐southeast plane and calculated the angle of tilt of the terraces to be 4 to 6 m/km or ∼0.3°.…”

“…Building on Campbell [1986] and Moore and Campbell 's [1987] earlier work, Faichney et al [2009] used recent high‐resolution multibeam bathymetry and dive video to identify and map the morphology of 12 submerged terraces off Lanai to a depth of 1200 m. Webster et al [2010] identified these terraces as reefs and presented 87 Sr/ 86 Sr isotopic age data that show they are older than their counterparts off the flanks of Hawaii. We have compiled and analyzed all existing and new high‐resolution multibeam bathymetry, dive observations, and chronologic data to investigate the tipping of the submerged terraces offshore the MNC and Oahu and to establish new constraints on lithospheric flexure associated with volcanic loading.…”

[1] There is considerable uncertainty concerning the history of lithospheric flexure of Oahu and the MauiNui Complex associated with the Hawaiian hot spot. Previous reconstructions based on models and sparse observational data place the zone of maximum uplift (forebulge) either under Oahu or between Oahu and Molokai. To address this issue we have compiled and analyzed all existing and new high-resolution multibeam bathymetry, dive observations, and chronologic data from submerged terraces in the region. We have identified 89 separate submarine terraces and mapped their distribution across the volcanic flanks of Oahu and the Maui-Nui Complex. These data are used to systematically measure the direction and amplitude of terrace tilting within the Maui-Nui Complex and to provide new constraints on lithospheric flexure associated with volcanic loading at the hot spot. The terraces are divided into six separate geographic regions (Oahu, Molokai, Penguin Bank, Lanai, Maui, and East Maui) defined by significant discontinuities in either terrace morphology or depth. Following the sequential development of new substrate as the new volcanoes formed throughout the development of the MNC, 18 new and 51 published 87 Sr/ 86 Sr isotopic ages show that the terraces in these regions were also initiated at different times, and the tilting data show that they also responded to lithospheric flexure independently. The general pattern of terrace tilting records the plate's response to lithospheric flexure with each region continually tilting toward the zone of maximum subsidence since their formation. Our individual tilt calculations are based on the most complete and highest-resolution bathymetric data available, and they show that plate response to volcanic loading is a gradual process. Finally, we demonstrate that the shallowest terraces we identified in the Oahu and Molokai regions tilt toward the north, away from the current zone of maximum subsidence, indicating that these regions have recently passed the zone of maximum uplift. We compare our results with two separate published numerical models and differentiate between these, resolving a long-standing uncertainty in the position of the forebulge.

Volcanic ocean islands and shield volcanoes form superb natural experiments for investigating changes in topography and hydrology over geologic time. As volcanoes age, their surfaces evolve from un-dissected, highpermeability landscapes into deeply dissected, low-permeability terrain. Here we review the tight links and co-evolution of topographic and hydrologic processes in volcanic landscapes. We discuss a number of factors that affect rates and patterns of hydrological and topographic co-evolution, including soil development, spatial and temporal variability of water availability, flank collapses, geologic architecture, and the tectonic history of subsidence or uplift. To illustrate the effects of climate on volcanic dissection, we compile a global dataset of volcanic landscapes and ages that suggests that substantial dissection begins between 0.5 and 2 million years after construction, with volcanoes in high-precipitation regions tending to become dissected more quickly than those in drier regions. Obtaining a deeper understanding of volcanic landscape evolution will require further research on several topics, such as the sensitivity of river incision to fluctuations in precipitation, the hydrologic responses of soil to chemical weathering and dust deposition, the evolution of chemical and physical erosion rates over a volcano's lifetime, the role of hydrology in triggering of flank collapses, and the extent to which the long-term evolution of an island is determined by the initial and boundary conditions set by geologic structure and regional tectonics.
