Which risk increases when highly viscous magma generates pyroclastic flows?

💡 Explanation

A silica-rich magma leading to pyroclastic flows increases regional sulfur dioxide concentration upon eruption via volatile exsolution, because SO₂ and other gases become trapped under viscous lava. Therefore, atmospheric loading increases, rather than affecting albedo because of the relatively short-lived nature of SO₂.
