Deployment of surface buoy
(Shows a boat next to a yellow buoy. A cable goes down to the sea floor and two anchors hold the buoy in place.)
Deployment of tsunameter
(Shows a tsunameter leaving the boat and falling to the sea floor next to the anchored surface buoy.)
Earthquake
(Shows everything shaking.)
Seismographs detect potential seismic activity
(Shows a building labelled JATWC or Joint Australian Tsunami Warning Centre where the seismographs are located.)
Tsunami
(Shows a wave passing over the tsunameter.)
Detects change in pressure
(Shows sensors on the tsunameter detecting change.)
(Shows a signal passing from the tsunameter to the surface buoy and up to a satellite in the sky. This beams it back to the JATWC building.)

Australia's tsunami detection system
The JATWC detects, monitors, verifies and warns of any tsunami threat to the coastline of Australia and its offshore territories.
