* Andesitic magma is a type of magma that is intermediate in composition, meaning it contains a mix of silica, magnesium, and iron. This composition often results in explosive eruptions with thick, viscous lava flows.
* Merapi's eruptions are often characterized by fast-moving pyroclastic flows, which are dangerous mixtures of hot gas, ash, and rock fragments.
While Merapi's magma is primarily andesitic, it can also contain small amounts of other magma types, such as basaltic magma which is more fluid and tends to produce effusive eruptions. However, the dominant type is andesitic, leading to its characteristically explosive eruptions.
