Abstract The devastating 2004 Indian Ocean tsunami caught millions of coastal residents and the scientific community off-guard. Subsequent research in basin has identified prehistoric tsunamis, but timing recurrence intervals such events are uncertain. Here we present an extraordinary 7,400 year stratigraphic sequence deposits from a cave Aceh, Indonesia. This record demonstrates that at least 11 tsunamis struck Aceh coast between 2,900 years ago. average time period is about 450 with...
Abstract We present stratigraphic, archeological and historical evidence for two closely timed predecessors of the giant 2004 tsunami on northern coast Aceh, Sumatra. This is first direct that a played role in fifteenth century cultural hiatus along Sumatran portion maritime silk route. One seacliff exposure eastern side Lambaro headlands reveals beds tsunamigenic coral rubble within small alluvial fan. Radiocarbon Uranium‐Thorium disequilibrium dates indicate emplacement after 1344 ± 3 C.E....
Marine inundation associated with the 5 to 8 m storm surge of Typhoon Haiyan in 2013 left overwash sediments inland on coastal plains northwestern shores Leyte Gulf, Philippines. The deposit provides a modern sedimentary record deposition from Category landfalling typhoon. We studied at two locations that experienced similar conditions but represent contrasting sedimentological regimes, namely siliciclastic coast and mixed siliciclastic-carbonate coast. local geology is significantly...
Brown, A.L.; Reinhardt, E.G.; van Hengstum, P.J., and Pilarczyk, J.E., 2014. A coastal Yucatan sinkhole records intense hurricane events.The potential of tropical sinkholes as archives for historical events has yet to be fully explored. This study uses high-resolution (1-cm interval) particle-size analysis examine two sediment push cores from Laguna Chumkopó, located on the Peninsula, Mexico. Core CKC1 (62 cm) was collected base a deep in Chumkopó at −79.9 m (msl), while second core, CKC2...
Wave set-up steepened and accentuated the storm surge during Typhoon Haiyan in November 2013 resulting bore-like flooding with heights of 7 m flow velocities reaching 5 s− 1 on open-sea coastal plain near Hernani. This study investigates two distinct sediment assemblages left behind by associated this surge. The first assemblage consists numerous boulders that now occupy reef flat, second pertains to a laterally extensive sand sheet blanketed up ~ 300 inland. majority has b axes between 2 m,...

Abstract Erosional and sedimentary features associated with flooding have been documented in both modern past cases. However, only a few studies demonstrated the relationship between these corresponding hydraulic conditions that produced them, making it difficult to evaluate magnitude of paleo-flooding. This study describes characteristics inundation depth flow direction, as well erosional resulting from disastrous Kinu River, central Japan, September 2015. Water levels rose rapidly due...
Abstract Hurricane Irma (September 2017) was one of the most devastating hurricanes in recent times. In January 2018, a post‐hurricane field survey conducted on Anegada (British Virgin Islands) to report erosional and depositional evidence caused by Irma's storm surge waves. We document type extent hurricane‐induced geomorphological changes, allowing for an improved risk assessment hurricane‐related inundation low‐lying islands carbonate platforms. Anegada's north shore impacted Irma. The...
Abstract Tsunami deposits preserved in the geological record provide a more comprehensive understanding of their patterns frequency and intensity over longer timescales; but recognizing tsunami can prove challenging due to post‐depositional changes, lack contrast between surrounding sedimentary layers, differentiating storm deposition. Modern baseline studies address these challenges by providing insight into modern spatial distributions that be compared with palaeotsunami deposits. This...
On September 16, 2015, a Mw 8.3 earthquake struck the north-central Chile coast, triggering tsunami observed along 500 km of coastline, between Huasco (28.5°S) and San Antonio (33.5°S). This provided unique opportunity to examine nature deposits in semi-arid, siliciclastic environment where stratigraphic sedimentological records past tsunamis are difficult distinguish. To improve our ability identify such evidence, we targeted one few low-energy, organic-rich depositional environments Chile:...
