There are 5,971 volcano images available on the GVP website, including 4,242 in these new galleries with updated captions and keywords, and at a larger size.
Volcanic ash (fragmented rock, crystals, and glass) can be the most far-reaching product and hazard during volcanic eruptions. Ash plumes can result in thick, heavy deposits near the volcano that can cause roofs, powerlines, branches, and other structures to collapse. Even a thin layer of ash on roads can make surfaces slick and dangerous. Depending on how fine the ash is, how prolonged the exposure is, and pre-existing conditions a person has, health impacts include respiratory effects, eye symptoms, skin irritation, and indirect effects (like injury from falling structures).
