True but somewhat slower... and have you tried to stop the tide?

Could be they were looking for a short, snappy and memorable name for an
unusually large ocean wave caused by an undersea earthquake. The japanese
have a name for such waves, perhaps because they live on islands in an area
of frequent earthquake activity, so it probably made sense to adopt the
term.

Don't be so silly!

What you need is one giant elastic band, placed round the island to
hold it together.
Then you can start to superglue it.



Or you could build a giant sea wall/dam around the island and pump out all
the water so there's no giant splash if/when the chunk falls off :-)

Lots of people have said that, but it seems unlikely. To create a tsunami
requires a high energy shock wave, a bit of land falling in would, however
large not be moving fast enough for the damage to be transmitted any
distance, although there would certainly be a large wave locally much as
when large icebergs break off.

Don't let science ruin a good discussion, that's Franz's job. :-)

I would recommend that they start making plans for evacuating New
York. They wil have around 10 hours warning. Perhaps theyhave
already made plans, but can't make them public because of the grand
panic which would follow immediately after the announcement.

Franz

Thanks Franz, knew we could rely on you ;-)

This is contentious. Have you read
http://www.benfieldhrc.org/CentreNew...es/tsunami.htm or
http://www.bbc.co.uk/science/horizon...anscript.shtml

More recent suggestions that it would break up before falling, and
"only" cause a wave 2 to 3m high have been made:
http://news.bbc.co.uk/1/hi/sci/tech/3963563.stm . That page has links
to sites that support and oppose the original tale.
It boils down to "we can't know the future".

But isn't the chunk of La Palma predicted to fall into the sea following
volcanic action?

True, however our language is peppered with words of 'foreign' origin,
adopted for one reason or another, it's one way it evolves.

I believe that was the earthquake and tsunami that wiped out Lisbon.

Why not use the Japanese word for earthquake too?

I *think* there's a technical difference. A tsunami is caused by an
undersea earthquake, or seaquake I suppose. Whereas a tidal wave can be
caused by a "landbased" earthquake. A tidal wave can also be caused by
storms or be one of those "megawaves" that swamp ships occasionally.

If you studied geology you'd have used the word frequently since at least
the mid 1970s.

That's the trouble. It was misleading. A tsunami has nothing at all to
do with tides, and that's why they changed it.

At least it indicates that it's a wave, whereas the word "tsunami" tells
the uninitiated naff-all.
Do you object to the name "slow worm"? Or toadstool? (to add the gardening
topic).
