The chances of a local source tsunami being generated by an earthquake in Pegasus Bay are low. This risk has not changed as a result of the recent earthquakes.
It is still important to know what to do if one does happen as there will be no time to issue an official warning.
Natural signs may be your only warning. Be ready to act if you are at the coast or within two blocks of the coast and experience any of the following:
Feel strong ground shaking that makes it hard to stand up;
See a sudden rise or fall in sea level;
Hear loud and unusual noises from the sea.
What to do
If you are on the beach or within two blocks of the coast, estuary or a river mouth and feel strong ground shaking that makes it hard to stand up:
- Move quickly inland or at least two blocks away from the coast, estuary or river mouth or to higher ground (at least four metres high). Use the safest route that you can. Within those first two blocks every step that you move inland or up hill, the safer you will be.
- If you can't quickly and safely get away from the coast, estuary or river mouth within five minutes (e.g. if you are in Southshore) then consider moving to the upper storey of a multi-storey building, or to the nearest high dune. You should aim to be at least four metres above sea level if you are still within two blocks of the coast. It is unlikely the water from a tsunami in Pegasus Bay would go higher than this.
- Only use your car if you have to. If you are at all able, evacuate on foot or by bicycle to avoid traffic jams. You are much more likely to get out if you are on foot or on a bicycle and you will leave more room on the road for those people who must use a car.
- Work out the best route to use from where you are located.
- Be aware that if the ground shaking is strong, there may be unstable cliffs and rockfall in hillside suburbs.
- Think about weather conditions.
- It is your responsibility to determine the best place for you and those with you to move to.
