Are composite volcanoes snow capped?
Many of the taller composite volcanoes and those located in cooler climates are snow-capped. However, others are not so tall and located in tropical regions and so do not have snow caps. On example is Mount Pinatubo in the Philippines.
When a snow-capped volcano erupts the heat can melt snow and ice. This can cause floods or, more often, mudflows called lahars. Such an event caused one of the worst volcanic disasters in recorded history. In 1985 a volcano in Columbia named Nevado del Ruiz erupted.Water from the melted glaciers at the mountain's peak generated a series of lahars that buried Armero and several other towns, killing 23,000 people.
