HOLOCENE VERTICAL MOVEMENTS OF THE KAMCHATKA PACIFIC COAST: GEOMORPHOLOGIC RECONSTRUCTION AND RELATION TO SEISMOTECTONIC PROCESSES
Since 1995 we have been conducting detailed field studies of the Holocene evolution and seismotectonic regime of selected areas on the eastern coast of the Kamchatka Peninsula (Fig.1). Specific methods of these investigations include: 1) application of tephrochronology and tephrostratigraphy [1] for...

| Summary: | Since 1995 we have been conducting detailed field studies of the Holocene evolution and seismotectonic regime of selected areas on the eastern coast of the Kamchatka Peninsula (Fig.1). Specific methods of these investigations include: 1) application of tephrochronology and tephrostratigraphy [1] for dating and correlation of various types of coastal deposits and landforms; 2) study of paleotsunami deposits [4,5,6] in order to determine their ages and recurrence rate and to estimate the magnitude of large tsunami and tsunamigenic earthquakes along the Kurile-Kamchatka subduction zone and north of the latter during Holocene time (last 10,000 years); 3) analysis of the geologic structure, age, and modern and paleo-topography of marine |
