Such magma is often shattered into pyroclastic fragments by explosive gas expansion during an eruption. Volcanic eruptions may fall into six major types:
Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian

What is volcano and its types?
There are three main types of volcano –
composite or strato, shield and dome
. Composite Volcanoes. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.
What are the 7 types of volcanoes?
The result is the classic cone shape of composite volcanoes. A cross section of a composite volcano reveals alternating layers of rock and ash: (1) magma chamber, (2) bedrock, (3) pipe, (4) ash layers, (5) lava layers, (6) lava flow,
(7) vent, (8) lava, (9) ash cloud
.
What type of lava erupts from a shield volcano?
Most shield volcanoes are formed from fluid,
basaltic lava flows
.
What is the largest volcano type?
The world's largest volcano, Mauna Loa in Hawaii, is
a shield volcano
, according to the U.S. Geological Survey. Mauna Loa is about 55,770 feet (17,000 meters) from its base beneath the ocean to the summit, which is 13,681 feet (4,170 meters) above sea level.

How many craters does Taal volcano have?
The island consists of different overlapping cones and craters, of which
forty-seven
have been identified. Twenty six of these are tuff cones, five are cinder cones, and four are maars.
What shape is a shield volcano?
Shield volcanoes, the third type of volcano, are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building
a broad, gently sloping cone of flat, domical shape
, with a profile much like that of a warrior's shield.

What volcano can destroy the world?
The Yellowstone supervolcano
is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it. This Yellowstone Volcano has been dated to be as old as 2,100,000 years old, and throughout that lifetime has erupted on average every 600,000-700,000 years.
What is the most powerful volcano on Earth?
The explosion of
Mount Tambora
is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index.
What is volcano in simple words?
A volcano is
an opening in the earth's crust through which lava, volcanic ash, and gases escape
. … Beneath a volcano, liquid magma containing dissolved gases rises through cracks in the Earth's crust. As the magma rises, pressure decreases, allowing the gases to form bubbles.
How many volcanoes are there on Earth?
There are about
1,500 potentially active volcanoes
worldwide, aside from the continuous belts of volcanoes on the ocean floor at spreading centers like the Mid-Atlantic Ridge. About 500 of those 1,500 volcanoes have erupted in historical time.
How many volcano types are there?
There are
three types
of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes.
