This resource is a joint Bureau of Meteorology (BOM) and Geoscience Australia media guide PDF designed to assist the media to communicate tsunami warnings to the Australian public. The resource explains the role of the Joint Australian Tsunami Warning Centre (JATWC) operated by Geoscience Australia and the Bureau. The resource includes a diagram showing the five categories of threat or warning once an undersea earthquake has been detected: No threat, Watch, Marine warning, Land warning and Cancellation. It includes the timing of each warning type and the action that should be taken by the media. It explains that the Standard Emergency Warning (audio) Signal (SEWS) is played on public media and used to alert communities to the broadcast of urgent safety messages relating to a major emergency or disaster.
