A general term for pyroclastic material ejected from a volcano. It includes ash, dust, bombs, and other types of fragments.
volcanic ash. In the Mediterranean, for example, deep-sea coring produced evidence for the ash fall from the eruption of Theta, and its stratigraphic position provided important information in the construction of a relative chronology.
The name given to pyroclastic materials of all shapes and sizes.
Collectively, all fragmental rock material ejected during a volcanic explosion or eruption
fragmented or molten volcanic rock material blown from a volcanic vent and transported through the air.
Unconsolidated accumulations of pyroclastic grains.
Any type of rock fragment that is forcibly ejected from the volcano during an eruption.
all sizes of solid igneous rock particles blown out from a volcanic vent
General term for all sizes of particles ejected into the air during volcanic eruption. Includes particles as tiny as volcanic ash and as large as bomb and blocks (= pyroclastic).
a general term covering all fragmental material expelled from a volcano (ash, bombs, cinders, etc.)
Collective noun for all sorts of volcanic material that are erupted from a crater or vent.
particles of either molten or rock erupted from a vent into the air above a volcano.
loose material, e.g., ash and pumice, deposited by volcanic eruptions; mantles extensive areas of the central North Island. Terrace: flat to gently sloping alluvial surface, elevated above floodplain level.
The general term used by volcanologists for fragments of volcanic rock and lava of any size expelled from a volcano.
Fragmented volcanic rock that has been transported through the air. Some is formed from lavas that have been blown from a vent and solidified as they fell, whereas others are formed from solid rocks that have been shattered and thrown into the air by explosions.
Materials of all types and sizes that are erupted from a crater or volcanic vent and deposited from the air.
Pyroclastic materials that fly from an erupting volcano through the air before cooling, and range in size from fine dust to massive blocks.
Material ejected into the air during a volcanic eruption. The particles can be as small as volcanic ash or as large as boulders and blocks, tens of feet in diameter
General term for all sizes of particles ejected into the air during volcanic eruptions. Includes particles as tiny as volcanic ash and as large as bombs and blocks (= pyroclastics). more details...
A general term used to describe any type of pyroclastic rock.
Solid material of all sizes explosively ejected from a volcano into the atmosphere.
fragments thrown into the air by a volcanic eruption
Airfall deposit from a volcanic eruption. Usually consists of distinctive, light-colored, well-sorted, gritty particles of ash.
All solid particles formed from material erupted into the atmosphere during volcanic eruptions.
A general term for all fragmented volcanic materials, including blocks of rock, pumice and volcanic ash.
A collective term for all unconsolidated volcanic material erupted explosively. Includes volcanic ash, pumice, scoria, volcanic bombs, some pyroclastic flows, etc.
Fragmented rock material ejected by a volcanic explosion. Also called pyroclastic material.
Material ejected during a volcanic eruption and carried through the air before being deposited; tephra deposits may range in size from volcanic bombs and blocks (64 mm), through lapilli (64-2 mm) to ash (2 mm).
Tephra is volcanic material that is airborne, like lava bombs, lapilli, and ash.
Tephra is air-fall material produced by a volcanic eruption regardless of composition or fragment size. Tephra is typically rhyolitic in composition as most explosive volcanoes are the product of the more viscous felsic or high silica magmas.
