multiple waves of Tsunami to hit Pacific Rim, how big?

Post Reply New Topic

And a lot depends on how narrow a harbor and what historically has happened with past tsunamis.

How do you evacuate (if necessary) less developed places like the eastern coast of the Philippines? Maybe enough of the people there still have Internet and cell phones, enough of a percentage.

Even in Haiwaii, people who just weren't watching TV today. I guess you use sirens and loud speakers from police cars.


Brace for possible tsunami after lunch Sunday – Phivolcs

"The Philippines can expect the arrival of the initial tsunami waves generated by the magnitude 8.8 earthquake in Chile after lunch of Sunday, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

"In a bulletin issued at 11:30 p.m. on Saturday, the Phivolcs said the estimated time of arrival of the first tsunami waves was between 1 p.m. and 2:30 p.m.

"The advisory warned 19 provinces on the eastern coast of the country to watch out for tsunami waves. . . "

The waves were smaller than expected in Hawaii, and the same will hold true for Japan.

Was about 20cm - 40cm here in Newcastle Australia if that, you could see the swell. A very strong rip current though, you'd be dragged right out to sea if caught in it.

Was very small in NZ, under a metre. A few days later a tall (approx +4m) wave broke on the Hawkes Bay Coast, but that may have been unrelated.

One of my friends in Japan reported that the waves were no more than a foot maximum, enough to cause some minor shore flooding but not like a Deep Impact-esque wave... although the Japanese media certainly took it that way. They had nonstop coverage from the time the earthquake hit until after the waves had passed, according to my one friend. They even cut into coverage of the 2010 Olympics. I can understand being concerned for one's country, but its almost like the only thing they mentioned about the actual quake was that it was what caused the tsunami. The NHK was like "oh, there was a quake in Chile" and then "OH MY GOD A TSUNAMI IS COMING WERE ALL GONNA DIE!" for a day and a half and then the m***et waves hit and they're like "Oh, well that was interesting".

Tsunamis are horribly destructive things. It is difficult to predict their size though it is easier to predict when they will reach land, as long as the cause is a fair distance away from the land and there happens to be monitoring equipment in the area of the situation which caused it.
