New Zealand is situated on the 'Ring of Fire', a geographic belt encircling the Pacific Ocean, containing about 90% of the Earth's volcanoes. There are six active volcanic regions in New Zealand.
WHAT IS A VOLCANO?
Volcanoes erupt when pressure builds up inside the earth and forces molten rock (magma) towards the surface. Volcanoes usually have short active periods, separated by longer dormant periods. Even extinct volcanoes are capable of coming to life again.
Those living in volcanic regions are at risk from ash, debris and lava flows. If there is a crater lake, water can mix with volcanic debris to form swiftly-moving avalanches of mud called 'lahars', which can kill and injure people and cause damage to property.
Before
- Know where active volcanoes are and whether they are likely to affect you.
- Have an evacuation plan - where to go and how to get there.
- Save water in your bath, basin and containers early on as supplies may become polluted.
During
- Stay indoors - keep windows and doors shut.
- If outdoors - find shelter.
- Listen to the radio for instructions.
- If told to leave, cover face and mouth and take your Getaway Items.
- Stay together.
- Do not go sightseeing.
- Take your outer layer of clothing off before entering a building - volcanic ash is difficult to get rid of.
After
- If in a safe place - stay put.
- Listen to the radio for information.
- Return home only when told.
