MAGMA

are sign that a volcano is/ might erupt. have toxic gases

Funes

are dangerous because rock fragments are sharp

pyroclastic materials

Classification of Volcano

Duration/Frequency Shape

Duration / frequency of Activities

ACTIVE, DORMANT, EXTINCT

currently erupting / showing signs

ACTIVE

has not erupted for 2kyrs, possible in future

DORMANT

period of dormancy exceded 10k yrs. lava supply cut off

EXTINCT

SHAPE

SHIELD, CINDER, COMPOSITE

broad, gently sloping land form basaltic lava

SHIELD

steep conical hill

CINDER

larger than cinder, can go bigger due to resistance erosion

COMPOSITE

most striking part of volcano

Cone

opening where molten nock escapes

Vent

large underground pool liquid rock beneath crust

Magma chamber-

basin like depression over a vent at the summit of a cone

CVMCC LMCS Cone Vent Magma chamber Crater Caldera Lava Magma Conduit Summit

3 stages of volcano's life

IBE Invasion of Magma Building Pressure Eruption

because of extreme temperature, magma rises through weak spots

Invasion of magma

due to the release of gases and water dissolved in molten rocks

Building pressure-

magma can no longer contained below earth's surface

eruption

95% volcanoes located near — 50% with

boundaries of tectonic plates mountains, plumes, and hotspots

discovered plumes & hotspot

John Tuzo Wilson

Theory states volcanic chains result —.

slow movements

areas or column where magma in mantle towards Earth's surface.

Mantle plumes

Located underneath continental oceanic crust or along plate boundaries

Mantle Plumes

are location on Earth's surface that have experienced active volcano activities.

Hotspots

—— how many identified hotspot in world.

40-50

Active sites of Volcanoes

DCCH - along divergent plate boundaries (spreading) - convergent - continental extension (underlying mantle is rising) - hotspots

refers to process & phenomena associated w/ surficial discharge of molten rock and other materials into surface of Earth.

Volcanism

Philippines is prone to volcanic eruptions. - because it is located in it can trigger another volcano eruption
