Image Collection | Hazards and Processes | Explosive Eruptions
There are 5,975 volcano images available on the GVP website, including 4,242 in these new galleries with updated captions and keywords, and at a larger size.
Explosive eruptions involve the rapid expansion of gas leading to the fragmentation of magma into volcanic ash, tephra, and blocks and bombs. Explosive eruptions can produce a range of hazards throughout an eruption or at the same time, with different hazards impacting different areas. Hazards include volcanic ash, ballistic ejecta, pyroclastic flows (also called pyroclastic density currents), volcanic lightning, volcanic gas, structural collapse (landslides or debris avalanches), and lahars.
