What was the wavelength of the 2004 tsunami?
For an earthquake-generated tsunami, the wavelength generally reaches a few hundred kilometres if the concerned fault is long. For the 2004 Sumatra earthquake, the wavelength is estimated, from the first wave measured by the Jason-1 satellite altimeter, as around 500–600 km (Gower 2005).
How tall was the wave that hit Thailand in 2004?
30 feet
This quake caused the Indian Ocean tsunami of 2004, which reached out across the Indian Ocean, devastating coastal areas with waves that in some places reached a height of 30 feet (9 metres) or more when they hit the shoreline.
Why did no one see the 2004 tsunami coming?
26, 2004, no one saw the massive waves coming. Authorities in Indonesia, where a 9.1 magnitude quake sparked the tsunami, weren’t able to send out an alert because the country’s sensor system had been hit by lightning. Thai officials did send a warning, but only after the first deadly wave hit.
How high were the waves in the Boxing Day tsunami?
Tsunamis reached 20m in height at landfall in parts of Aceh. In other locations they spread 3 km inland carrying debris and salt water with them. The retreating waters eroded whole shorelines.
How high is a tsunami wave?
100 feet
Tsunamis generally reach a maximum vertical height onshore, called a run-up height, of no more than 100 feet above sea level. A notable exception was the 1958 tsunami triggered by a landslide in a narrow bay on Alaska’s coast. Its over 1,700-foot wave was the largest ever recorded for a tsunami.
What type of wave is a tsunami?
Tsunamis are ocean waves triggered by:Large earthquakes that occur near or under the oceanVolcanic eruptionsSubmarine landslidesOnshore landslides in which large volumes of debris fall into the water Scientists do not use the term “tidal wave” because these waves are not caused by tides.
How far did the 2004 tsunami travel inland?
2 km
In many places, the waves reached as far as 2 km (1.2 mi) inland.
How do animals sense tsunamis?
Wildlife experts believe animals’ more acute hearing and other senses might enable them to hear or feel the Earth’s vibration, tipping them off to approaching disaster long before humans realize what’s going on.
