The violent release of energy from a volcano is known as an eruption. Gas and magma from beneath the earth's surface are under great pressure. The gas and magma find the path of least resistance and burst through the central vent of the volcano.

Mount Merapi is an explosive volcano. It is one of the most active and dangerous volcanoes in Indonesia, known for its frequent and violent eruptions that release large amounts of ash, gas, and lava.
A stratovolcano, also known as a composite volcano, is formed from violent eruptions characterized by explosive activity that ejects a mixture of lava, ash, and volcanic rocks. These eruptions are typically associated with high levels of gas pressure within the magma chamber, leading to explosive events.
Stratovolcano (a composite volcano)
A quiet eruption, also known as an effusive eruption, is characterized by the slow and steady flow of lava from the volcano without significant explosions or ash plumes. An example is the 2018 eruption of Kilauea in Hawaii. A violent eruption, also known as an explosive eruption, involves the sudden release of gas, ash, and debris with explosive force. An example is the 1980 eruption of Mount St. Helens in the United States.
There is no volcanoes on the sun, but sometimes a large energy release known as a solar flare can be mistaken for a volcano.

Komaga-take Volcano is one of the most active volcanoes in Japan. It is located on the Oshima Peninsula of southern Hokkaido and is known for its violent and explosive explosions.
The Eyjafjallajokull Volcano is a composite volcano, also known as a stratovolcano. Composite volcanoes are characterized by their steep slopes and violent eruptions due to the combination of explosive eruptions and lava flows.

A stratovolcano, also known as a composite volcano, has steep sides and is known for its explosive eruptions due to the high viscosity of its magma. These eruptions are often characterized by the ejection of pyroclastic material, lava flows, and volcanic ash. Mt. St. Helens in Washington State is a famous example of a stratovolcano with violent eruptions.
Krakatau is a stratovolcano. This type of volcano, also known as a composite volcano, is characterized by a tall, conical shape with very steep sides. The explosions are usually extremely violent.
Didicas Volcano is a stratovolcano, so its eruption style is typically explosive and can produce ash plumes, pyroclastic flows, and lahars. This type of volcano is known for its violent eruptions due to the high viscosity of its magma, which can lead to dangerous volcanic hazards.
A violent storm on the sun is called a solar flare. It is a sudden and intense eruption of electromagnetic radiation from the sun's surface. Solar flares can release energy equivalent to millions of nuclear bombs exploding at the same time.
