dc.description.abstractThe study and preservation of tsunami deposits have being challenging in humid tropical environments. While tsunami deposits have been widely studied at temperate latitudes, few studies assess this problem in tropical environments due to the difficulties intrinsic to these places (e.g. tsunami deposit preservation, post-burial changes in a tropical environment, mangrove vegetation, difficult access, wildlife, among others). Here we assess the problem of tsunami-deposits preservation on the Jalisco-Colima tropical coast of Mexico, which parallels the more than 1000-km long Mexican subduction, where historical accounts indicate the occurrence of two significant tsunamis on June 3 and 22, 1932 (Corona and Ramírez-Herrera, 2012a, Valdivia et al., 2012). However, up to date, no geological evidence of these events has been reported. We present geological evidence of two large tsunamis related to the June 3, M 8.2 earthquake, and the June 22, Ms 6.9 landslide-triggering event of 1932 (Corona and Ramírez-Herrera, 2012a, b). A multiproxy approach was applied to unravel the nature of anomalous sand units and sharp basal contacts in the stratigraphy of a number of sites at Palo Verde estuary, El Tecuán swales and marsh, and La Manzanilla swales, on the Jalisco-Colima coast. Lines of evidence including historical, geomorphological, stratigraphic, grain size, organic matter content, microfossils (diatoms and foraminifera), geochemical content, magnetic susceptibility and AMS analyses, together with dating (210Pb and 14C), and modeling, corroborate the presence of tsunami deposits of both the 3 June 1932 tsunami at El Tecuán and La Manzanilla, and the 22 June 1932 tsunami at Palo Verde. Further evidence of earlier tsunamis, at least four events, is also evident in the stratigraphy. Work in progress should reveal the chronology of the earliest tsunamis and their origin.
