“…(2) The presence of an underplated layer beneath Santa Maria may explain the uplift trend of this island over the last 3.5 Ma years (Ramalho et al 2017). Similar arguments have been made to explain the uplift and evolved volcanism of some of the Canary Islands under which magmatic underplating is seismically observed (Schmincke et al 1997;Klügel et al 2005;Lodge et al 2012). The islands São Miguel and Santa Maria lie on the oldest lithosphere of the Azores Plateau, which could be a factor for accumulation of an underplated layer.…”

“…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).…”

“…However, the geological record of many eroded islands (e.g. Madeira Island in the Madeira Archipelago, La Palma in the Canaries, and Santiago in Cape Verde) does not exhibit evidence for an emergent surtseyan phase Schmincke, 2000, 2002), but rather an erosive unconformity between the seamount series and the subaerial products (see Serralheiro, 1976;Klügel et al, 2005a;Brum da Silveira et al, 2010;Ramalho, 2011). This probably means that the transition between seamount and emersed island may take place through mechanisms other than summit volcanism.…”

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.

“…This is clearly indicated by the petrology and geochemistry of magmas from monogenetic eruptions, which evidence certain degree of differentiation in most cases and occasional assimilation of crustal rocks that occurred at different depths (Thirlwall et al, 2000;Klügel et al, 2005;Stroncik et al, 2009;Valentine and Hirano, 2010;Brenna et al, 2011;Rowe et al, 2011;Hernando et al, 2014;Albert et al, 2015Albert et al, , 2016Klugel et al, 2015). These intermediate reservoir zones, which will normally be located at rheological or structural discontinuities inside the lithosphere, do not need to be stable or permanent along the whole history of the volcanic field.…”

The factors controlling the preparation of volcanic eruptions in monogenetic fields are still poorly understood. The fact that in monogenetic volcanism each eruption has a different vent suggests that volcanic susceptibility has a high degree of randomness, so that accurate forecasting is subjected to a very high uncertainty. Recent studies on monogenetic volcanism reveal how sensitive magma migration is to the existence of changes in the stress field caused by regional and/or local tectonics or rheological contrasts (stratigraphic discontinuities). These stress variations may induce changes in the pattern of further movements of magma, thus conditioning the location of future eruptions. This implies that a precise knowledge of the stress configuration and distribution of rheological and structural discontinuities at crustal level of such volcanic systems would aid in forecasting monogenetic volcanism. This contribution reviews several basic concepts relative to the stress controls of magma transport into the brittle lithosphere, and uses this information to explain how magma migrates inside monogenetic volcanic systems and how it prepares to trigger a new eruption.
