Tsunami Waves travelling as fast as commercial jet planes
February 28th, 2010 by Brad HeapEarlier today Thomas Beagle on Twitter posted “Kind of weird to think about water sloshing around the planet.” This made me stop and think for a second not just how weird it is, but also how powerful it is.
The 8.8 magnitude earthquake which struck on Saturday was big enough to issue a Tsunami Warning for all these countries:
CHILE / PERU / ECUADOR / COLOMBIA / ANTARCTICA / PANAMA / COSTA RICA / NICARAGUA / PITCAIRN / HONDURAS / EL SALVADOR / GUATEMALA / FR. POLYNESIA / MEXICO / COOK ISLANDS / KIRIBATI / KERMADEC IS / NIUE / NEW ZEALAND / TONGA / AMERICAN SAMOA / SAMOA / JARVIS IS. / WALLIS-FUTUNA / TOKELAU / FIJI / AUSTRALIA / HAWAII / PALMYRA IS. / TUVALU / VANUATU / HOWLAND-BAKER / NEW CALEDONIA / JOHNSTON IS. / SOLOMON IS. / NAURU / MARSHALL IS. / MIDWAY IS. / KOSRAE / PAPUA NEW GUINEA / POHNPEI / WAKE IS. / CHUUK / RUSSIA / MARCUS IS. / INDONESIA / N. MARIANAS / GUAM / YAP / BELAU / JAPAN / PHILIPPINES / CHINESE TAIPEI
In the case of Auckland, New Zealand it is about 10,000km from the epicentre of the earthquake. Not only is it amazing that water can travel so far over such a big distance and have a massive effect* on a country so far away, it is also impressive the speed at which the wave travels. New Zealand has felt the effects of the wave 12 – 15 hours after the earthquake, to put that in comparison the flight time from Chile to New Zealand is 13 hours on an Airbus A340. The Tsunami wave is travelling at around the same speed as a jetliner. That is a very scary thought.
The Tsunami may not be a tree but the age old philosophical question of “If a tree falls in the forest and no one is around to hear it does it make a sound?” is answered very much yes with the way in which the entire world responses to the threat of a Tsunami.

*Massive Effect – I don’t take this to mean widespread distruction, I take this to mean Tidal Surge Chart showing a water movement of 1m+, Widespread Civil Defense warnings, Evacuations of people from low lying costal areas, cancellations of events and warnings for people to stay off beaches, pretty much anything that impacts the daily lives of many thousands of individuals.
