Abstract |
Seven recent case studies on volcanism-induced tsunami deposits are reviewed. These regard the tsunamis related to the Managua, Santorini, Aniakchak, Komagatake, Kurakatau, Rabaul and Karymskoye eruptions. The most distinct feature of these tsunami deposits is a 'pumiceous sand' layer. This is a mixture of pumice and beach sand; both are transported and deposited inland by a tsunami. The possible origin of the pumice in the layer is drift pumice, reworked pumice and primary pumice fallout during the tsunami run-up. This unique sediment layer is often observed in near-source tsunami deposits of volcanic origin. Chronological correlation of tephra and tsunami deposits provides a rare opportunity to study the tsunami-generating process during the eruption. Volcanism-induced tsunami deposits are informative, especially for studies of eruptionrelated tsunamis that occurred in the prehistory. |
