Top 5 Facts: Tsunamis

Harbour wave

In Japanese the word tsunami literally translates as ‘harbour wave’. Tsunamis are a frequent occurrence in Japan, with other 195 recorded throughout history so far.

Ancients

It was the Greek historian Thucydides who first linked tsunamis to earthquakes. However, their exact cause remained speculative until the 20th Century.

Brakes

Out as sea tsunamis travel incredibly quickly, often clocking up over 500mph. This speed slows as it reaches the shoreline, often being reduced to around 50mph.

Quick draw

The first part of a tsunami to reach land is referred to as a ‘trough’. Here water along the shore recedes dramatically in a mass drawback, exposing normally submerged areas.

Monitoring

Due to their destructive nature, tsunami-related activity is monitored by specialist observation centres such as the Pacific Tsunami Warming Center in Honolulu.

    My dog loves to look up at birds flying overhead. He will be laying on the deck and see a shadow pass overhead and jump up barking and chasing the bird in the sky. Not all dogs do this. Some you can not coax into looking up at the sky. they just don’t get it. but my dog loves looking at birds in the sky and chasing them barking!! Inside you can see him moving his eyes within a certain radius just as we do.
