Popis:

Pyroclastic flows sweep down the east flank of Volcán de Fuego — in October 1974, Guatemala.

• One of the largest historical eruptions of Volcán de Fuego.
• Ash clouds rise off the base of the pyroclastic flows, which traveled up to 7 km from the summit at estimated average velocities of 60 km/hr.
• The travel direction of pyroclastic flows is influenced by topography. The denser basal portion of the pyroclastic flows follows topographic lows on the flanks of the volcano — note a smaller pyroclastic flow descending a gully at the right.
