How is tsunamis measured

WebA megatsunami is a tsunami with an initial wave amplitude measured in many tens, hundreds, and possibly up to thousands of metres. A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms. Normal tsunamis result from displacement of the sea floor due to plate tectonics. http://www.bom.gov.au/tsunami/info/

WebOut in the open ocean, tsunami waves are only about one-metre high because the water is deep. However, as the water becomes shallow, the waves slow down and begin to grow. They can rise 35m or higher – that’s the same as a 10-floor block of flats! However, the scariest thing about a tsunami is its wavelength, as this determines how far ...

WebTsunami – a killer wave – speeding across the ocean at 400 miles an hour. It smashes into land destroying everything in its path. Tsunamis do not have a season. But they can strike any coast at any time. If one forms close to the shore, the shaking of the earth and a loud roar may warn of its approach. WebOn the other hand, the tsunami buoy needs to be close enough to the epicentre to enable timely detection of any tsunami and maximise the lead time of tsunami forecasts for coastal areas. In addition, tsunami buoys must ideally be placed in water deeper than 3000m to ensure the observed signal is not contaminated by other types of waves that have …
