“…With respect to discussing possible earthquake scenarios for prehistoric earthquakes, our spatio-temporal event stratigraphy for the area south of 39.0 • N reveals the most promising data from the deep subsurface of the basins JTS01, JTS15, and JTC07-JTC11. The 2.3 (+0.4/-0.2) ka event deposit identified in the basin JTS15 is probably related to the 2.4-2.6 ka earthquake that has been inferred from a tsunami deposit reported along the coast between the northern Fukushima and southern Miyagi Prefectures (e.g., Kusumoto et al, 2018). Yet, interpretation of an earthquake trigger for this event deposit may not be unique, because the correlation of the event deposit with a wide possible age range cannot be constrained by our basin-to-basin correlation.…”

Kioka et al. Japan Trench Event Stratigraphy historic large earthquakes are highly variable. We conclude that at least 7 Tg (10 12 g) of organic carbon remobilized from surficial slope sediments is exported to the hadal axis of Japan Trench in the last 2,000 years by giant earthquakes. These findings highlight the significance of seismo-tectonic events for the long-term carbon cycle in hadal trenches and societal implications.

“…Hurricane and tsunami deposits mostly result from onshore transport of near-shore sediment and exhibit a number of similar characteristics (e.g., Morton et al, 2007). Many criteria have already been defined to distinguish tsunami from storm deposits (e.g., Goff et al, 2004 ;Morton et al, 2007 ;Engel et al, 2016 ;Kusumoto et al, 2018), however, these criteria are most of the time site-dependent. Among the 25 F3 deposits, two deposits display specific criteria which may contribute to their identification as tsunami records.…”

The Lesser Antilles are a densely populated and a very touristic region exposed to many short-term hazards such as hurricanes and tsunamis. However, the historical catalog of these events is too short to allow risk assessment and return period estimations, and it needs to be completed with long-term geological records. Two sediment cores were sampled in March 2018 in a small coastal lagoon on Scrub Island (north eastern Caribbean). Here, we present sedimentological, geochemical, microfaunal and chronological analyses that enabled us to identify 25 sandy layers resulting from high energy marine floods. Two of these layers were interpreted as tsunami deposits based on sedimentological and geochemical evidence. The most recent deposit is associated with the transatlantic tsunami triggered by the 1755 AD Lisbon earthquake. The older is the thickest sandy layer recorded in the lagoon and is dated at 1415 cal. AD (1364-1469 cal. AD). This event was recorded in both the northern and the southern part of the Caribbean, with its large extent supporting a tsunamigenic origin. The 23 remaining sandy This is a non-peer reviewed preprint submitted to EarthArXiv The manuscript is under review at Sedimentary Geology 2 layers were interpreted as resulting from hurricanes, with the three most recent layers being associated with historical hurricanes. This new 1600 year-long reconstructed chronicle, has been compared to other published hurricane chronicles from the region. Scrub chronicle is the most eastern site and displays similarities with that of the Bahamas, while it is in antiphase with that of the north eastern US coast. This regional comparison may provide evidence of a latitudinal forcing for the hurricane tracks through time in relation to climate fluctuations.

“…The confirmation of tsunami needs further studies on land, as the differentiation criteria (e.g. depositional thickness) were established based on the comparison of the modern typhoon and tsunami-induced deposits in the coastal lagoon and marsh (Kitamura et al, 2020; Kusumoto et al, 2018; Moreira et al, 2017; Morton et al, 2007). For the YJ core in the northern SCS (Figure 1b), there is also a reverse 14 C age in the core depths at 79 cm (2999 cal yr BP) and 99 cm (2750 cal yr BP) (Huang et al, 2018), which further indicates that the huge storm tides occurred in South China.…”

Typhoon is an important meteorological phenomenon that affects the living and development of human beings on the southern China coast. However, there is still lack of clarity in the paleo-typhoon history and its influence on the evolution of the ancient human settlement environment since the mid-Holocene. Here, we identify six typhoon-like deposits from a core retrieved from the northern South China Sea shelf, close to the Pearl River Estuary, based on accelerated mass spectrometry 14C dating, grain size, and geochemistry. The sand fractions, CaO, Sr, SiO2/TiO2, and SiO2/Al2O3 were used to indicate the typhoon-like deposits. Results show that the ages with high-frequency typhoons are present ~200–300 cal yr BP, ~800–1000 cal yr BP, ~1500–1700 cal yr BP, ~2000–2100 cal yr BP, ~2400–2500 cal yr BP, and ~2700–3000 cal yr BP. Our results are comparable to the records from adjacent regions. Significantly, the vast tides occurred in the duration of ~2700–3000 cal yr BP in southern China, which probably caused the ancestors’ migration to the inland. Further studies are needed to deeply study the paleo-typhoon history in the southern China coast to verify our results.
