Mapping and Reconstructing the Paleotsunami Record in Queule, South-Central Chile
… sea level fall after the deposition of the two paleotsunami sand deposits that changed the geomorphology of the coast and limited the accommodation space necessary to preserve additional overwash sediments could explain the 5000-year hiatus with no evidence of earthquakes or tsunamis. Further …

Assessing the Use of Tsunami Simulations as a Tool to Predict Source Magnitudes and Locations of Paleoearthquakes in Chile
A long-term goal of paleotsunami studies is the ability to predict paleoearthquake parameters based on tsunami deposits found on land. Chile provides an exemplary location for testing methods of making these predictions because the historical record includes 41 major earthquakes as far back as 1562 …

Geomorphology of Deposits from the 2004 Indian Ocean Tsunami, Tamil Nadu, Southeastern India
… in future attempts to discover and identify paleotsunami deposits in the geological record from India, and elsewhere.</p>

Mapping and Modeling the Seattle Fault Tsunami Inundation in Puget Sound
… Deer Lagoon and Doe-Kag-Wats, for evidence of a paleotsunami record to combine with tsunami modeling, in order to predict how future events could inundate Puget Sound. A deposit, interpreted as a paleotsunami, is traceable thought the marsh stratigraphy near the modern day tidal inlet of Deer …

Sediment Provenance of Tsunami Deposits: Implications for Assessing the Relative Intensity of Paleotsunamis from the Sendai Coastline of Japan
… of past tsunamis remains unclear. To understand paleotsunami intensity, it is important to document characteristics of modern analogues like the 2011 event. This study utilizes surface distributions of foraminifera from coastal and offshore locations within Sendai Bay to determine the provenance …

Investigating Taphonomic Changes of Deposits and Modeling of the 2010 Earthquake and Tsunami in South-Central Chile
… that GeoClaw modeling based on preserved paleotsunami deposits could provide useful estimates of tsunami-generating earthquake characteristics in south-central Chile, provided better resolution bathymetry and topography are available.

Refining tsunami inundation limits for the 1700 CE Cascadia earthquake: detailed mapping of fine-grained deposits and diatom biostratigraphy at the Salmon River estuary, central Oregon
… approach to additional CSZ sites will improve paleotsunami reconstructions, providing more accurate constraints on earthquake and tsunami source models and enhancing future hazard assessments that are critical for improving community resilience.

Assessing the Rates of Post-Depositional Change Within 2004 Indian Ocean Sediments: Implications for Long-Term Records of Paleotsunamis
<p>Foraminifera are commonly used to examine patterns of tsunami inundation occurring over centennial to millennial timescales, but the impacts of post-depositional change on geologic reconstructions are unknown. In Sumatra, the taphonomic character (i.e., test surface condition) of a foraminifer …

Catastrophic Tsunamis In the Indonesian Archipelago
… on seismotectonic assessment, historical record, paleotsunami deposits and micro-atoll studies, as well as volcanic type and activities. Most of the volcanogenic tsunamis sources are located in the eastern archipelago around the Banda Arc and the Molluca Sea. Tsunamis from volcanic sources had …
