Colima

A convecting ash column roils above a small, but impressive-looking pyroclastic flow from Colima volcano in Mexico on April 16, 1991. The pyroclastic flow, colored by the late-afternoon sun, was produced by collapse of unstable portions of the summit lava dome. It descended the SW flank but caused no damage to inhabited areas.
