Natural Science Forum / Earth Science / Earthquakes / January 2005

I just noticed that Linda Howe of Earthfiles.com is going
to be on the Coast-to-Coast program this Friday night
(Jan 21) to discuss the the threat of a mega-tsunami from
Cumbre Vieja.

Take a look at the msh volcanocam:

There's a definite glowing spot where the plume can be seen to be
coming from during the day.

George, Yes, it does tell me something about me, and much else:

Nevermind.

  First of all, what the hell am I looking at? Those images
are of such low quality I can't tell heads or tails of what's
what. It looks to me like a kid scribbled all over some maps

Let's start with the basics...  TSUNAMI is a Japanese word which means
"HARBOR WAVE".
But, as we've now seen all too vividly in the December 26, 2004 9.0

I just found out that Indonesia is requiring our military
personal to leave the country. The same personal who are
trying to bring aid to the victims of the tsunami and
help rebuild critical infrastructure to get help in quicker.

This is just a reminder that the earthquake contest is on.  Here is a link to

I am curious as to how tsunami waves can move so fast, and why they do so.
If you throw a rock in a pond, the ripples radiate at a much more leisurely
pace, and even if you shoot a fast bullet into water, the ripple don't
radiate proportionally faster.

In Message 27 Nosterill wrote quoting Skywise quoting my ebook at
nodrift.com :

Message 1 ended: ". . . . [Ward et al] looked specifically for impact
clays or material ejected from a crater left by such an impact."
