Download Impact of a Volcanic Eruption on Agriculture and Forestry in New Zealand

Volcanic eruptions will produce a number of hazards, some of which will make their effect felt hundreds of kilometres distance from the volcano. Volcanic planning differs from planning for most other hazards such as floods and drought which are generally predictable in their extent, have a short term warning period, and be of short duration. A volcanic event can build up over weeks to years and be unpredictable in its probable course and timing.
