Not wishing to cause alarm, but isn't it just as likely to have a
tsunami in the Atlantic as it is in the Indian ocean.

Donno to be honest but the mid Atlantic rift is a spreading zone not a
subduction or sliding one. It's the latter areas that give rise to the
large earthquakes required to trigger tsunamis.


I think the UK East coast is at greater risk than the west. There is a
geological record of tsunami's along the East coast which is, iirc,
particularly good along the Firth of Forth and Tay valleys.

As for creating a Tsunami Warning System for the Indian Ocean after an
extreme 1 in 700 year event, I'm not so sure it is necessary or viable.

Well clearly, it was necessary and I don't understand why it isn't
viable. Some experts have thought it necessary, too - there was a
recent conference on this very subject and the participants must be
kicking themselves that it didn't take place a few years ago with,
possibly, a warning system up and running by now. The Pacific Tsunami
warning system is an established model to base it on.

Are deadly Indian Ocean tsunamis really 1 in 700 year events? I
wouldn't have thought the conference would even have been suggested if
that were so. Or are we talking about 9.0 earthquakes in the Indian
Ocean? Which is not the same thing at all, is it?

AFAICT, there were 12 destructive Tsunami's in the pacific basin in the
past 10 years.

IANE, and I am relying mostly on sound-bites, one of which is that this
is Sri Lanka's first recorded (destructive?) Tsunami.

I understood it to be that there was a major slipping of the Indian
plate and the Eurasian plate every 700 years. ICBW, and there are, of
course, other sources for geological activity.

I don't know. Perhaps the area is less prone to earthquakes. But didn't
Lisbon suffer very severely from one sometime in the 18th century?

And do we have an early warning system?

I understand that, unlike the Indian Ocean, the Pacific Ocean does, but
I've no idea about the Atlantic.

I shouldn't have thought that the North Sea or the area to its north was
very geologically active, so I'm rather surprised. Are you sure that
these were true tsunamis rather than storm surges?

Isn't there a volcano on one of the canary islands that has a good
probability of collapsing into the atlantic and causing a tsunami?

Yes, the Cumbre Vieja volcano on La Palma.

The book 'Apocalypse-A Natural History of Global Disasters' by Bill McGuire
(UCL), pub by Cassell ISBN 0304352098 makes sombre reading. Cumbre Vieja is
descibed in Ch.3

It cost £15 when I bought it in 2000, Amazon UK currently quote same price
but not sure how readily available it is. '2 available in US' at much higher
price.

I wonder if there is any news on Joe Hunt and his family? I truely hope
they
are ok.

Yes they are fine Alex, but it seems as if it was a close run thing as
water poured into their hotel. He has sent some amazing photos of the
area
nearby.

I suspect Joe would be happy for them to be shared with the ng and have put
them here :-

Yes. The seabed around Scandinavia is pretty much like Scandinavia
itself. There are many steep precipices which, when they collapse, can
cause tsunami's. The reference I have repeatedly heard wrt North Sea
Tsunami's is the Storegga slide which apparently caused a really big one
in the distant past.

A google for "north sea tsunami storegga" produced a lot of hits which I
will have to trawl through later.
