Volcanism is one of the main mechanisms transferring mass and energy between the
interior of the Earth and the Earth's surface. However, the global mass flux of lava, volcanic …

The breaking apart of magma into fragments is intimately related to the eruptive style and
thus the nature and footprint of volcanic hazards. The size and shape distributions of the …

Atmospheric CO 2 exerts a robust and well-documented control on Earth's climate, but the
timing of glaciation during the late Paleozoic Ice Age (LPIA; ca. 360–260 Ma) is inconsistent …

Juvenile pyroclasts, especially in the ash size range, provide important information on
primary fragmentation processes, ie, initial explosive magma fragmentation, and on the state …

To quantify the size of tephra, two practical challenges must be addressed: the wide range of
particle sizes (10− 8-10 1 m) and the diversity of particle shape, density and optical …

Pyroclastic density currents (PDCs) are hazardous and destructive phenomena that pose a
significant threat to communities living in the proximity of active volcanoes. PDCs are ground …

This study aims to conduct a spatiotemporal analysis of the long-range transportation of
volcanic ashes that originates from the eruption of the Sangay volcano and reached …

Several powerful explosive eruptions have taken place in the populated lower East Rift Zone
of Kīlauea within the past∼ 750 years. These have created distinctive landforms, including a …

Volcanic tephra fall deposits, which form during explosive eruptions, are commonly
characterized in terms of their thickness and grainsize. While significant efforts have been …

Reliable reconstructions of tephrostratigraphy and emplacement mechanisms of Early to
Middle Miocene volcaniclastic deposits across the Alpine-Mediterranean region may yield …
