ANDESITIC VOLCANO Meaning and
Definition
-
An andesitic volcano is a type of volcano that is characterized by its composition and eruptive behavior. It falls under the category of stratovolcanoes, which are tall, steep-sided volcanoes built up by alternating layers of lava, ash, and other volcanic materials.
Andesitic volcanoes derive their name from the Andes mountain range in South America, where many of these volcanoes are found. They are formed by the eruption of andesite, a type of volcanic rock that is intermediate in composition between basaltic lava (from shield volcanoes) and rhyolitic lava (from caldera volcanoes). Andesite is rich in silica, magnesium, iron, and other minerals, giving it a distinctive composition.
These volcanoes are characterized by their explosive eruptions caused by the high viscosity (thickness) of the andesitic magma. The high silica content in the magma makes it less fluid and more prone to gas buildup, resulting in explosive eruptions that may release pyroclastic flows, ash clouds, and lava bombs. The steep slopes of these volcanoes are a result of the accumulation and hardening of these volcanic materials over time.
Andesitic volcanoes are commonly found in subduction zones, where one tectonic plate is forced beneath another. The subducting plate melts, forming the andesitic magma that rises to the surface and erupts, thus building the volcano. Notable examples of andesitic volcanoes include Mount Mayon in the Philippines, Mount Shasta in the United States, and Mount Ruapehu in New Zealand.

Etymology of ANDESITIC VOLCANO
The word "andesitic" is derived from the name of the Andes mountain range in South America. It describes a type of volcanic rock known as andesite, which is commonly found in the Andes region. Andesite is primarily composed of plagioclase feldspar and volcanic glass, with smaller amounts of other minerals like amphibole and pyroxene. Hence, an "andesitic volcano" refers to a volcanic cone or mountain formed by the eruptions of andesitic lava.
