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.
- Talk with your family about an emergency plan and what you will need at home.
- Talk to your family about an evacuation plan – where to go and how to get there.
During
- Listen to the radio for instructions.
- Stay indoors – keep windows and doors shut. Bring your pets indoors if you can.
- Save water in your bath and other containers at an early stage, as the water supply may become polluted.
- If outdoors, find shelter.
- If told to leave, cover your face and mouth, wear a dust mask and goggles if you can, and take your essential emergency survival items.
- 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.
