Tsu nami de pos its have not pre vi ously been re corded along the south ern coast of the Bal tic Sea. The re sults of pres ent research pro vide ev i dence of high-en ergy event lay ers that oc cur on the bot tom of two hemi spher i cal hol lows cut into glaciolimnic silt and glaciofluvial sand and gravel of Late Weichselian age. The event de pos its are rep re sented by poorly sorted ma rine sand with ad mix tures of peb bles and allochthonous biogenic de tri tus: ma rine, brack ish and oc ca sion ally fresh wa ter shells and shell de bris of bi valves and snails, plant macrofossils from the nearshore zone, shreds and lumps of peaty ma te rial, gyttja and organogenic silt, lumps of char coal, wood pieces and tree branches and trunks. All these fea tures are com monly con sid ered in dic a tive of tsu na mis. The age of the biogenic de tri tus found in the tsu nami layer ranges from 6,630 to 10,390 cal. yr BP, whereas the old est gyttja cov er ing the event lay ers is 6,600 cal. yr BP old. This means that the tsunami oc curred be tween 6,600 and 6,630 cal. yr BP. Var i ous causes of the tsu nami event are con sid ered, in clud ing the impact of me te or ites within the coastal plain and the lit to ral zone of the south ern Bal tic Sea.

“…Sediment layers from Saliña Tam and Klein Bonaire interpreted as extreme wave deposits fulfill several criteria commonly associated with tsunami and/or storm wave impacts, such as a basal unconformity, reworked underlying material, graded bedding, increased mean grain size, peaks in marine indicator ions (Ca, Sr), increased CaCO 3 content as well as marine microfossils showing signs of reworking (Switzer and Jones, 2008;Mamo et al, 2009;Peters and Jaffe, 2010). However, in the sedimentary record, differentiating between deposits of tsunamis and waves generated by extraordinary storms is challenging (Bridge, 2008) since most onshore sedimentary features attributed to either one may be generated by both hydrodynamic processes (Sugawara et al, 2008).…”

Shoreline changes and high-energy wave impacts at the leeward coast of Bonaire (Netherlands Antilles)

Supralittoral coarse-clast deposits along the shores of Bonaire (Netherlands Antilles) as well as increased hurricane frequency during the past decade testify to the major hazard of high-energy wave impacts in the southern Caribbean. Since deducing certain events from the subaerial coarse-clast record involves major uncertainties and historical reports are restricted to the past 500 years, we use a new set of vibracore and push core data (i) to contribute to a more reliable Holocene history of regional extreme-wave events and (ii) to evaluate their impact on shoreline evolution. Multi-proxy palaeoenvironmental analyses (XRF, XRD, grain size distribution, carbonate, LOI, microfossils) were carried out using nearshore sedimentary archives from the sheltered western (leeward) side of Bonaire and its small neighbour Klein Bonaire. In combination with 14 C-AMS age estimates the stratigraphy reflects a long-term coastal evolution controlled by relative sea level rise, longshore sediment transport, and short-term morphodynamic impulses by extreme wave action, all three of which may have significantly influenced the development of polyhaline lagoons and the demise of mangrove populations. Extreme wave events may be categorized into major episodic incidents (c. 3.6 ka [?] BP; 3.2-3.0 ka BP; 2.0-1.8 ka BP; post-1.3 ka [?] BP), which may correspond to tsunamis and periodic events recurring on the order of decades to centuries, which we interpret as severe tropical cyclones. Extreme wave events seem to control to a certain extent the formation of coastal ridges on Bonaire and, thus, to cause abrupt shifts in the long-term morphodynamic and ecological boundary conditions of the circumlittoral inland bays.

“…Even if foraminifera, as a group have a cosmopolitan distribution and inhabit the entire marine realm, some individual taxa are well known to be restricted to specific environmental niches (for instance, marsh and brackish environments). This characteristic represents a useful instrument for palaeogeographic analysis and palaeoenvironmental reconstruction (e.g., Mamo et al, 2009). Moreover, due to their small size (between ∼100 µm and 2 cm), foraminifera possess both a high preservation potential within the sedimentary record after death and distinct diagnostic test shape.…”

Abstract. Analysis of tsunami deposits from the Pantano Morghella area provided geological evidence for two inundations occurred along the south-eastern Ionian coast of Sicily. Pantano Morghella is a large pond characterised by a finegrained sedimentation indicating a low-energy depositional environment. Two anomalous yellow sandy layers found at different depths indicate the occurrence of high-energy marine inundations. We studied sedimentological and paleontological features of the anomalous deposits as well as their spatial distribution observing the following properties: different facies with respect to the local stratigraphic sequence; erosive bases, rip-up clasts and broken elements testifying violent deposition mechanisms; macro and micro fauna of marine environment; relatively constant thickness throughout most of the depositional zone with thinning at the distal end; large sand sheets that extend inland. These observations, jointly with their infrequency in the sedimentary record and the age indicating a fast deposition, provided strong evidence for tsunami inundations. Correlations between anomalous layers and historical tsunamis are supported by radiocarbon and OSL dating results. The younger deposit is likely due to the 1908 near-source tsunami, whereas the flooding of the oldest event is most likely associated with a far and large source, the Crete 365 AD earthquake.
