“…For example, islands located on plates that are stationary with respect to their melting source, such as the Cape Verdes, are prone to long term uplift movements (up to 400-450 m at 0.4 mm/yr) possibly driven by basal intrusions and by hotspot swell growth Ramalho et al, 2010a,b,c;Ramalho, 2011). Cumulative far field effects of surface loading by other islands in the vicinity may also cause uplift, as is inferred for O'ahu (0.02-0.07 mm/yr), Moloka'i (0.04-0.19 mm/yr), and Lana'i (0.15-0.29 mm/yr) in Hawai'i, and for other Pacific uplifted atolls in the Cook-Society island region (McNutt and Menard, 1978;Grigg and Jones, 1997;Rubin et al, 2000;McMurtry et al, 2010). Likewise, islands located near active plate margins may experience uplift as a result of dynamic topography (near divergent plate margins) or plate flexure/buckling associated with outer trench rise (near convergent plate margins) (Karig et al, 1976;Melosh, 1978).…”

“…The role of flexural rebound associated with mass wasting and erosional unloading may also add a modest contribution to uplift, as has been suggested to some of the Hawaiian and the Canary Islands (Smith and Wessel, 2000;Menendez et al, 2008). A detailed appraisal of oceanic island uplift mechanisms, magnitudes and rates is outside the scope of this paper; for that we recommend the reader to works such as Smith and Wessel (2000); Zhong and Watts (2002); Ali et al (2003); Klügel et al (2005a); Ramalho et al (2010a,b); Madeira et al (2010);McMurtry et al (2010);Ramalho (2011).…”

“…In a similar fashion, accretion rates may differ according to environmental and oceanographic conditions and will have a profound effect on reef morphology. Local uplift -whose origins are still poorly understood or are the focus of hot debate (see Scott and Rotondo, 1983;McNutt and Menard, 1978;McMurtry et al, 2010;Ramalho et al, 2010b) -may further contribute to the variability in reef morphology. It is now perceived that the diversity of modern reef morphology essentially arises from the combined effects of island subsidence (or sometimes uplift), coral accretion rates, and Pleistocene glacioeustatic cycles (Woodroffe et al, 1999;Toomey et al, 2013).…”

The growth and decay of oceanic hotspot volcanoes are intrinsically related to a competition between volcanic construction and erosive destruction, and coastlines are at the forefront of such confrontation. In this paper, we review the several mechanisms that interact and contribute to the development of coastlines on oceanic island volcanoes, and how these processes evolve throughout the islands' lifetime. Volcanic constructional processes dominate during the emergent island and subaerial shield-building stages. During the emergent island stage, surtseyan activity prevails and hydroclastic and pyroclastic structures form; these structures are generally ephemeral because they can be rapidly obliterated by marine erosion. With the onset of the subaerial shield-building stage, coastal evolution is essentially characterized by rapid but intermittent lateral growth through the formation of lava deltas, largely expanding the coastlines until they, typically, reach their maximum extension. With the post-shield quiescence in volcanic activity, destructive processes gradually take over and coastlines retreat, adopting a more prominent profile; mass wasting and marine and fluvial erosion reshape the landscape and, if conditions are favorable, biogenic processes assume a prominent role. Posterosional volcanic activity may temporarily reverse the balance by renewing coastline expansion, but islands inexorably enter in a long battle for survival above sea level. Reef growth and/or uplift may also prolong the island's lifetime above the waves. The ultimate fate of most islands, however, is to be drowned through subsidence and/or truncation by marine erosion.Keywords complex, interplay, between, volcanism, erosion, sedimentation, sea, level, islands, change, coastal, biogenic, production, oceanic, evolution, volcanic, GeoQuest Disciplines Medicine and Health Sciences | Social and Behavioral Sciences Publication DetailsRamalho, R.

“…dance of dated paleoshoreline markers (Jones, 1993b;McMurtry et al, 2010), the Hawaiian Islands provide a unique opportunity to study coupled lithosphere and mantle dynamics. Here we examine the contributions of volcanic loading and mantle buoyancy to observed rates of Hawaiian island vertical motion.…”
