Historical and paleo-tsunami deposits on Kamchatka, Russia: long-term chronologies and long-distance correlations
International audience 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...
