The first continuous late Pleistocene tephra record from Kamchatka Peninsula (NW Pacific) and its volcanological and paleogeographic implications
Highlights • First continuous MIS 2 explosive eruptions record from the Kamchatka volcanic arc. • 25 major tephra markers with a potential for regional and hemispheric correlations. • The largest (M ≥ 6.5) eruption originated from the Gorely eruptive center ∼28 ka BP. • The high quality geochemical...
