Flashcards
Active Volcanoes
Active Volcanoes
Volcanoes that have erupted recently or are currently erupting.
Inactive Volcanoes
Inactive Volcanoes
Volcanoes that haven't erupted in recorded history. They are still potentially active but are considered 'sleeping'.
Potentially Active Volcanoes
Potentially Active Volcanoes
Volcanoes that are classified as active but have not erupted in a long time. They are considered 'asleep' but could potentially erupt again.

Study Notes
Volcanoes - Types and Activity
- Learning Objectives: Differentiate volcanic architectures, explain their formation, describe volcano parts, compare active and inactive volcanoes, and explain different eruption types.
Types of Volcanoes by Activity
-
Active Volcanoes: These volcanoes have eruptive histories, meaning a recorded eruption in historical times. Examples include: Mt. Kilauea, Mt. Mayon, Mt. Taal, Mt. Etna, Mt. St. Helens.
- Currently, 23 active volcanoes are being monitored by PHIVOLCS.
- Dateable erupted materials confirm eruptions within the last 10,000 years. Mt. Vesuvius (79 AD) is considered a historically dangerous eruption.
- Four most active in the Philippines: Mt. Mayon (52 eruptions), Mt. Taal (34 eruptions), Mt. Kanlaon (30 eruptions), Mt. Bulusan (18 eruptions).
- Mt. Mayon's "perfect cone" structure signifies it's a stratovolcano.
- Mt. Taal last erupted in 2020
- Mt. Kanlaon last erupted in 2016
- Mt. Bulusan last erupted in 2017.
-
Inactive Volcanoes: These volcanoes have no eruptive history, are heavily weathered, and will not erupt again. Examples include Mt. Arayat and the Seven Lakes of San Pablo.
- PHIVOLCS lists 335 inactive volcanoes, some unnamed.
-
Potentially Active Volcanoes (Dormant): These volcanoes have no recorded eruptive history and no recent dateable materials. Still, some show signs of activity or residual heat. Examples include Mt. Apo, Mt. Talinis, and Mt. Isarog.
- PHIVOLCS lists 26 potentially active volcanoes.
Key Points
- PHIVOLCS classifies Philippine volcanoes based on their activity.
- Active volcanoes have erupted historically.
- Potentially active volcanoes lack historical eruption records but may show morphological signs of recent activity.
- Inactive volcanoes have never erupted and are heavily weathered.
- The Philippines' location in the Ring of Fire leads to considerable volcanic activity.
