A tsunami can impact the WA coastline as a land or marine threat. Regardless of which threat is issued, follow the advice of DFES and the Bureau of Meteorology. If required to evacuate, do not return to the shore after the first wave. Wait for DFES officials to give the All Clear before you return.
During a tsunami, you can expect dangerous rips, waves, and strong currents that may last for several hours.
When there is a marine threat beaches, rock pools and other foreshore areas are not safe, and there may be some localised land flooding immediately adjoining the foreshore.
During a land threat, there may be flooding to low-lying coastal areas, dangerous waves and strong ocean currents that may last several hours.
Tsunamis that present a land threat are much less frequent than those that present a marine threat. However, when they do occur, they are extremely dangerous.
If a tsunami is threatening your location, you should relocate to a safer place early. Leaving at the last minute could put your life in danger. When relocating, walk if possible to avoid traffic congestion.
After a tsunami, there is the risk of flooding in low-lying coastal areas and estuaries. Water can be deep, fast flowing with strong currents and have sharp objects that can injure or trap you. It is important to know the dangers of driving in flood waters.
Due to the following hazards, travelling during or after a tsunami can be extremely dangerous:
If tsunami inundation impacts roads, the same considerations apply as those for areas impacted by floodwaters.
If a road is closed, obey road closures and check road conditions if there are no signs.
If you choose to shelter in your home during a tsunami, it is essential that you first know the risks, understand what you may experience and follow these steps:
Even if you have planned well, life-threatening situations can still happen. Your shelter could be damaged, or someone could become ill or injured.
For life-threatening emergencies, call 000.
Emergency services will try to come to your aid. However, there may be delays due to the dangerous conditions.
If your property is damaged and unsafe, call the State Emergency Service on 132 500 for assistance.
Once the tsunami risk has passed and the All Clear has been issued, you can leave your safe place. However, you must do so with caution and follow the safety advice in the warning. Do not return to the water until you have received official advice that it is safe to do so.
It’s critical that you know how to access different information sources to stay up to date during an earthquake.
During mobile network outages, radio is often the most reliable source of information. It is essential to have a battery-powered radio or another device capable of receiving broadcasts on AM/FM frequencies to stay informed in such situations.
