Many New Zealanders live in coastal communities. A major earthquake, landslide or volcanic eruption can create massive tidal waves that could be disastrous for these communities. We only need to recall the recent major disaster in Asia to understand just how destructive these natural occurrences can be.
If a Tsunami were to threatened New Zealand shores, a Tsunami warning would be issued by the Ministry of Civil Defence and Emergency Management. These national warnings would be relayed to the public through radio and television broadcasts.
However if the tsunami is one that is generated close to our coastline by a strong earthquake (New Zealand has experienced a few of these), there may not be enough time to issue a warning. You need to understand what to do if a Tsunami threatens.
Before a Tsunami Strikes
- Know how to reach the nearest high ground (at least 35 metres above sea level) and make it part of your emergency plan. Identify where you could go if a Tsunami threatened and make sure all family members are aware of this plan.
- Prepare an emergency survival kit that can easily be grabbed if you need to evacuate.
- Keep your insurance cover up-to-date.
How to Recognise a Tsunami
- If an earthquake, landslide or volcanic eruption is felt or reported near and you are based near the coast, be aware of the possibility of a Tsunami.
- Turn on your radio and listen for any information or warnings.
- Be aware of the water level as it may fall very quickly past the normal low tide mark, then return just as quickly.
- You may here the loud rumbling sound of a Tsunami approaching.
When a Tsunami Threatens
- Leave the area immediately if you are on the beach or near a river when a strong earthquake occurs.
- Go at least one kilometre inland or 35 metres above sea level.
- Turn on your radio and follow all instructions.
- Take your Survival Kit with you if you are told to evacuate.
- Don’t go to a river or beach to watch the waves come in.
