The orphan Sanriku tsunami of 1586: new evidence from coral dating on Kaua‘i

We have re-examined the historical evidence in the circum-Pacific for the origin of the 1586 orphan tsunami of Sanriku, Japan, previously attributed to a Lima, Peru, earthquake and tsunami in 1586. New evidence comes from corals found in a unique paleotsunami deposit on Kaua‘i. Dated by 230Th-238U geochronology these corals determine an absolute age in high precision of a Pacific tsunami event that was previously dated to approximately the sixteenth century by 14C methodology. Detrital…

History and features of trans-oceanic tsunamis and implications for paleo-tsunami studies
Abstract Far-field tsunamis and their features, as well as methods to quantify trans-oceanic tsunamis are reviewed, with examples of instrumental and historical data. Tsunamis from the 1854 Nankai
Tephra in caves: Distal deposits of the Minoan Santorini eruption and the Campanian super-eruption
Abstract Tephra deposits in caves are not only significant as stratigraphic markers. The comparatively sheltered position of cave environments, protected from rainfall, may preserve original distal
Dating tsunami deposits: Present knowledge and challenges
Abstract Dating approaches for fine sediment tsunami deposits can be divided into two categories: (1) dating directly using materials from within a tsunami deposit, and (2) dating indirectly using
Palaeotsunamis in the Sino-Pacific region
ABSTRACT Palaeotsunami research in the Sino-Pacific region has increased markedly following the 2011 Tōhoku-oki tsunami. Recent studies encompass a variety of potential sources and cover a full range

A millennial-scale record of Holocene tsunamis on the Kronotskiy Bay coast, Kamchatka, Russia
Abstract Deposits from as many as 50 large tsunamis during the last 7000 years are preserved on the Pacific coast of the Kamchatka Peninsula near the mouth of the Zhupanova River, southern Kronotskiy
New Evidence from the East Polynesian Gateway: Substantive and Methodological Results from Aitutaki, Southern Cook Islands
East Polynesia was the geographic terminus of prehistoric human expansion across the globe and the southern Cook Islands, the first archipelago west of Samoa, a gateway to this region. Fourteen new
Paleotsunami evidence on Kaua‘i and numerical modeling of a great Aleutian tsunami
The Hawaiian Islands' location in the middle of the Pacific Ocean is threatened by tsunamis from great earthquakes in nearly all directions. Historical great earthquakes Mw > 8.5 in the last 100
Historical and paleo-tsunami deposits on Kamchatka, Russia: long-term chronologies and long-distance correlations
Abstract. Along the eastern coast of Kamchatka, at a number of localities, we have identified and attempted to assign ages to deposits of both historic and prehistoric (paleo-) tsunamis. These
Fossiliferous Lana'i deposits formed by multiple events rather than a single giant tsunami
It is shown that the Hulopoe gravel was formed by multiple depositional events, separated by considerable periods of time, thus invalidating the main premise of the ‘giant wave’ hypothesis.
A Millennium of Human Activity at Makauwahi Cave, Māhāūulepū, Kauaūi
Old maps, an 1824 sketch, records of the Land Court Awards, and old photographs confirm stratigraphic inferences and oral accounts concerning demographic and ecological conditions of the early historical period.
Marine incursions of the past 1500 years and evidence of tsunamis at Suijin-numa, a coastal lake facing the Japan Trench
Sandy deposits of marine origin underlie the floor of Suijin-numa, a coastal lake midway along the subduction zone marked by the Japan Trench. The deposits form three units that are interbedded with
It is confirmed that the prehuman lowlands of dry leeward Kaua’i included plants and animals previously known only in wetter and cooler habitats, and efforts to restore lowland areas in the Hawaiian Islands must take into account the evidence from this study.
Late Holocene great earthquakes in the eastern part of the Aleutian megathrust
Abstract The great earthquake, Mw 9.2, of AD 1964 may not be typical of other megathrust earthquakes in the region during the last 4000 years. We present new field data from three sites: Copper River
Palaeotsunamis in the Pacific Islands
The recent 29 September 2009 South Pacific and 27 February 2010 Chilean events are a graphic reminder that the tsunami hazard and risk for the Pacific Ocean region should not be forgotten. Pacific
