classification morphology

Shield Volcanoes

A volcano produced by the accumulation of fluid basaltic lavas and exhibit the shape of a broad, slightly domed structured that resembles a warrior's shield, with gently sloping flanks, 15° or less

Stratovolcano

Also called Composite volcanoes, built from interlayered tephra and _ lava flows, generally products of gas-rich andesitic magma. It is gradually sloping, 10° to 30°, and considered as most dangerous and eruptive.

Pyroclastic Cones

A volcano composed mostly of loose ejected ash, and some lava, appearing relatively symmetrical and steeply built, with large, deep craters, with most being produced by a single eruptive event.

Scoria Cones

A volcano that is dominantly composed of vesicular, basaltic material.

Cinder Cones

A volcano composed of various composition

Caldera

A large depression, >1km in diameter, typically caused by collapse of the summit area of a volcano following a violent eruption, or due to depletion of the magma chamber following the collapse of the overlying material due to the absence of supporting underlying material.

Super volcano

A volcano that had an eruptive history that reached VEI 8

Yellow stone Volcano

A massive caldera complex in Wyoming, USA, famous for its super volcano eruptions primarily due to It being hotspot that produces acidic magma and lava.

Active Volcano

A classification of Volcanoes according to PHILVOLCS that Had a recorded eruption for the past 600 years, and has datable material for 10,000 years ago

Potentially Active Volcano

A classification of Volcanoes according to PHILVOLCS that is Geomorphologically young volcano that Is currently not erupting, but is supposed to erupt again

Inactive Volcano

A classification of Volcanoes according to PHILVOLCS that Has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.

Active Volcano

A classification of volcanoes according to USGS that Had at least one eruption during the past 10,000 years.

Dormant Volcano

A classification of volcanoes according to USGS that Had No historically recorded eruption or had not erupted in thousands of years but is likely to erupt in the future.

Extinct Volcano

A classification of volcanoes according to USGS that Had not erupted within recorded history and is not likely to erupt again, and shows no manifestations of any volcanic activity

Volcano Explositivity Index

A systematic classification of volcanic eruptions based on observations during an eruption

Tephra, Column Height, Eruption Style, Description, and Duration

Classification of VEI
