Volcanic Eruption Flashcards
Taal Volcano is located in?
Tagaytay
Mayon Volcano is located in
Albay
- It is a vent on the earth’s surface that opens downward to aa pool of molten rocks, debris and gases.
- formation involves the process of subduction
- subduction takes place when two plates converge
- subduction zone is the place where two plates converge

3 classification of volcanoes:
- active volcano
- potentially active volcano
- inactive volcano
One of classification of volcanoes that is currently erupting or is showing signs of volcanic eruption.
Active volcano
One of classification of volcanoes which has erupted and then entered a long period of inactivity
Ex: Mt. Pinatubo
Potentially Active Volcano
One of classification of volcano that has not shown any sign of activity for a long period.
Ex: Mt. Cabalian in Leyte
Inactive Volcano
Volcanic Eruption Hazards:
- lava flows
- pyroclastic flows
- pyroclastic surges
- tephra falls
- ballistic projectiles
- volcanic gas
- lahar
One of the volcanic eruption hazards which is a mass of magma that flows down the slope of the volcano.
Lava flow
One of the volcanic eruption hazards that refers to hot dry masses of fragmented volcanic materials that move along the slope and in contact with ground surface at a speed greater than 60 kilometers per hour.
Pyroclastic flow
One of the volcanic eruption hazards that are turbulent low-concentration density currents of gases, rock debris, and in some cases, water, that move above the ground surface at high velocities
Pyroclastic Surges
One of the volcanic eruption hazards that showers of fine corase-grained volcanic materials
Tephra Falls
One of the volcanic eruption hazards that rocks are released into the air by an errupting volcano.
Ballistic Projectiles
