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 deposits are dated and correlated using tephrochronology from Holocene marker tephra and local volcanic ash layers. Because the historical record of earthquakes and tsunamis on Kamchatka is so short, these investigations can make important contributions to evaluating tsunami hazards. Moreover, because even the historical record is spotty, our work helps add to and evaluate tsunami catalogues for Kamchatka. Furthermore, tsunami deposits provide a proxy record for large earthquakes and thus are important paleoseismological tools. The combined, preserved record of tsunami deposits and of numerous marker tephra on Kamchatka offers an unprecedented opportunity to study tsunami frequency. Using combined stratigraphic sections, we can examine both the average frequency of events for each locality, and also changes in frequency through time. Moreover, using key marker tephra as time lines, we can compare tsunami frequency and intensity records along the Kamchatka subduction zone. Preliminary results suggest real variations in frequency on a millennial time scale, with the period from about 0 to 1000 A.D. being particularly active at some localities.

“…We (1) outline the types of turbidite systems found along the Cascadia margin and analyze the channel pathways where the best turbidite event records are preserved; (2) describe the turbidite sequences found in each system; (3) present the radiocarbon, X-ray, computed tomography (CT), visible image, and physical-property data from the core sites; (4) examine the evidence for triggering mechanisms of the Holocene Cascadia turbidites for synchroneity and for stratigraphic correlation of individual events over large distances; (5) present evaluation of the turbidite record as a paleoseismic record for the Cascadia subduction zone; (6) assess the combined onshore and offshore paleoseismic record and propose recurrence intervals and rupture lengths for Holocene great earthquakes in Cascadia; (7) discuss earthquake probabilities and possible recurrence models; and (8) discuss implications of the correlation records for the potential recording of paleoearthquake-source information.…”

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.
