1 million years
The dominantly andesitic Galeras volcanic complex has been active for more than 1 million years, and two major caldera collapse eruptions took place during the late Pleistocene. Long-term extensive hydrothermal alteration has affected the volcano.
What is volcano full information?
A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. Volcanic eruptions are partly driven by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne.

A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.

What is a volcano Class 7?
A volcano is a vent from which a combination of melted rock, solid rock debris and gas erupts. It has a reservoir of molten material below the surface (magma chamber) called magma, and when this magma rises to the surface, it is called lava.
What type of eruption does Galeras volcano have?
Recently, eruptions at Galeras have been characterized by Vulcanian explosions, pyroclastic flows, degassing (especially of sulfur dioxide), and ash plumes.
Is Galeras volcano still active?
It is currently the most active volcano in Colombia. Galeras has been an active volcano for at least a million years, with andesite as the dominant product. Two major caldera -forming eruptions have occurred, the first about 560,000 years ago in an eruption which expelled about 15 cubic kilometres (3.6 cu mi) of material.

Is Galeras volcano cinder composite or shield?
Shield volcano eruptions are less explosive than composite volcanoes. Cinder cone volcanoes are steep, cone-shaped volcanoes built from lava fragments called ‘cinders.’. These volcanic cinders
