🌊 Tsunami are caused by sudden movement of the ocean surface. They are generally triggered by earthquakes but can also be triggered by landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean. We cannot predict when a tsunami will happen, but we can forecast how and where the tsunami will travel, and which coastal zones are at risk. Once our National Earthquake Alerts Centre is alerted to a seismic event that could trigger a tsunami we deliver a rapid response and engage protocols under the Joint Australian Tsunami Warning Centre. We recently joined partners from around the country in exercise PacWave, a national exercise and testing of the Australian Tsunami Warning System, which simulated an earthquake-generated tsunami in the Pacific Ocean. Collaborating with various partners and under the coordination of Bureau of Meteorology, we tested Australia’s national systems to ensure we are well-placed to respond to a potential tsunami threat, and to see if changes could improve the effectiveness of our response.
