Revisiting the role of high-energy Pacific events on the environmental and cultural history of Easter Island (Rapa Nui)

Pacific islands are spread over thousands of kilometers of the Oceanic Basin and are characterized by similar ecological features but very diverse geologic origins, from steep volcanoes to flat coral atolls. Several climatic phases have been shared among the region within the last 1000 years. Numero...

Several climatic phases have been shared among the region within the last 1000 years. Numerous and abrupt societal and cultural changes during the same period have been described for islands separated by thousands of kilometers. Conspicuous societal changes have been exclusively attributed to the main climatic patterns (changes in precipitation and temperature).

For example, the extreme Samalas eruption in AD1257 may have been an indirect driver of the sudden population decline, land degradation and decreased food resources on many Pacific islands between AD1250 and 1300, and the Kuwae eruption in AD1450 may have triggered the synchronous end of long voyaging expeditions across the Pacific. Important paleotsunamis have had unquestionable impacts on coastal and seafaring societies. A direct effect of the main eruptions of the last millennia (AD1257 and 1453) on Easter Island has not yet been identified by any record, but we have calculated, the likelihood of destructive tsunamis with an estimated period of recurrence for large events of less than a century.This insight is new and needs to be taken into account to complement what we already know about Easter Island cultural history and archeological sites, especially those in vulnerable coastal locations.Wiley2018info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersionapplication/pdfhttps://hdl.handle.net/2445/124463Articles publicats en revistes (Dinàmica de la Terra i l'Oceà)reponame:Dipòsit Digital de la UBinstname:Universidad de BarcelonaInglésVersió postprint del document publicat a: https://doi.org/10.1111/geoj.12253Geographical Journal, 2018, vol. 184, num. 3, p. 310-322https://doi.org/10.1111/geoj.12253(c) The Royal Geographical Society, 2018info:eu-repo/semantics/openAccessoai:diposit.ub.edu:2445/1244632026-05-27T06:46:51Z
