Styles of Eruptions and Volcanic Hazards

Styles of Eruptions and Volcanic Hazards. Styles of volcanic eruptions. Some volcanoes may erupt only once - monogenetic (Diamond Head) Other volcanoes erupt many times - polygenetic (Kilauea) Some erupt very gently (Kilauea)

VOLCANOES

VOLCANOES. TYPES OF VOLCANOES. Volcanoes are classified by appearance Steep slopes = Strato/composite Volcanoes Gentle slopes = Shield volcano. Appearance predicts type of eruption Steep slopes ? explosive (violent) eruptions Gentle slopes ? non-violent (quiet) eruptions.
