- Changes in ground temp.
- Small short-lived eruptions may announce a larger one
Typical Eruption Warning probs... - Most of these events are not followed by a major

Mt. Vesuvius - Strato volcano in S Italy
- Near populated Naples Italy

flows
Large Volcanic Eruptions - Have the capability to affect the Earth's global climate, at least
for a few years.
- Very large ash clouds stall in the high atmosphere, where they block parts of the radiation that
Earth receives from the sun. Less radiation= Cooler temps.
- Volcanic gases can have similar affect
