Volcano information source book

Mt Taranaki is a potentially active volcano.

The most recent activity is thought to have been in the mid 19th Century. Although the probability of an eruption is relatively low in any one year, the probability of one occurring in the fugture is hgih.

The timing of the next eruption cannot yet be determied but its probable effects can be reasonably assessed. Eruptions overseas have demosntrated the impacts of volcanic activity on nearby landscapes, communities and the economy. Even the 1995-1996 Ruapehu eruptions, although small by world standards, highlighted the vulnerability of communities to minor eruptions.

Another consideration is that more often than not, indications of volcanic activity such as increased earthquakes or above-ground gas changes, may not result in an eruption. These "unrest" phenomena may be hazardous in themselves and cause uncertainty among the population and decision-makers.

Volcanic crises must be planned for using a comprehensive emergency management approach that links the "four Rs" - reduction, readiness, response and recovery.

This report, commissioned by the Taranaki Civil Defence Emergency Management (CDEM) Group and prepared by GNS Science, provides a review of key information for the effective management of volcanic hazards at Taranaki.

The CDEM Group regards this as a most useful report and urges everyone in Taranaki to consider the information it contains and to consider  what preparedness and mitigation measures you may need to take, both as as an individual and as part of an organisation.
