occurs when magma is expelled from a volcanic vent

molten rock that erupts form a volcano and solidifies as it cools

molten rock beneath the earth’s surface

areas near volcanoes which usually surrounded by hot springs and boiling mud pool

carbon dioxide, sulfur dioxide are some gases

meaning of PHIVOLCS

highest point of a volcano

small cone shaped volcano

also called lahar, violent, fast moving suspention of water,ash, and rocks

largest and most violent type

recently erupted within 10,000 years

lava quiently and steadily flow out of a volcano

side of a volcano

solid materials that are thrown out during volcanic eruption

red hot with a very high temperature

underground passage magma travel through

are described to produced the largest eruptions

contains larger amount of gases and are faster that pyroclastic flows

thick and mostly flattened layer of cooled lava

mouth of a volcano

a cloud of ash

fast moving current of hot gases and rock

simplest type of volcano

use the heat beneath the earth’s surface

are giant ocean waves created by underwater earthquakes

also known as composite volcano

lava is thrown into the air in jets

are chunks of lava blasted into the air

also known as mud flows

an opening, gap or crack on earth’s surface

created when magma erupts in underwater

hydromagmatic eruption where lava interact explosively with water

formed from a nonexplosive eruption of lava

has not erupted thousands of years ago and there is no possibility of eruption

build by slow eruption of high viscous lava

smallest type is explositions which consists of intermittent

entrance of a volcano

fragments material that consists of pumice,scoria,lithic

an opening in an earth’s surface through volcanic materials escape

large bowl shaped depression

a flat piece of rock formed when magma hardens

lava violently explodes out of a vent

violent type of eruption which accompanied by violent gun shots

fragments of lava rocks that are blasted into the air

has not erupted in long time but there is a possibility that it can erupt in the future
