Volcanic edifices consist of diverse suites of pyroclastic successions, originated from primary (e.g. tephra fall, lava flow) and reworking processes (e.g. alluvial activity). The volcanoclastic sediments have witnessed the magma fragmentation and subsequent transportation mechanism as flow, turbulent current or tephra fall. Such pyroclastic deposits therefore hold key evidence to understand volcano-stratigraphy, eruption re-occurrence rates, and dominant transportation modes. This session aims to discuss sedimentary and volcanological aspects of volcanoclastic deposits. We invite presentations covering (1) field-based description and interpretation of volcanoclastic sediments, (2) reconstruction of eruptive and sediment transport processes, (3) experimental and numerical simulation of volcano-related sediment transport, and (4) development of new methodologies to understand the formation of volcanoclastic sediments. These topics are critical to understand volcanic phenomena and to improve upon existing volcanic monitoring efforts, and to forecast volcanic hazards in the future.
