<p>The coastal deposits of Bonaire, Leeward Antilles, are among the most studied archives for extreme-wave events (EWEs) in the
Caribbean. Here we present more than 400 electron spin resonance (ESR) and radiocarbon data on coarse-clast deposits from
Bonaire’s eastern and western coasts. The chronological data are compared to the occurrence and age of fine-grained extreme-wave
deposits detected in lagoons and floodplains. Both approaches are aimed at the identification of EWEs, the differentiation
between extraordinary storms and tsunamis, improving reconstructions of the coastal evolution, and establishing a geochronological
framework for the events. Although the combination of different methods and archives contributes to a better understanding
of the interplay of coastal and archive-related processes, insufficient separation, superimposition or burying of coarse-clast
deposits and restricted dating accuracy limit the use of both fine-grained and coarse-clast geoarchives to unravel decadal-
to centennial-scale events. At several locations, distinct landforms are attributed to different coastal flooding events interpreted
to be of tsunamigenic origin. Coastal landforms on the western coast have significantly been influenced by (sub)-recent hurricanes,
indicating that formation of the coarse-clast deposits on the eastern coast is likely to be related to past events of higher
energy.
