not Thor'sday yet.)

The First Law of the occurrence of earthquakes is that (for the North
Atlantic basin for example) as the magnitude of the high pressure air
masses increases and the magnitue of the low pressure air systems
decreases (or is that an increse.. ? no.. I want to steer clear of
positive and negative terms...) then the magnitude of earthquakes
earthwide increases.

The same holds true for the reverse effect, that as the pressures of
the air systems become or remain similar, the magnitude of earthquakes
diminishes or remains small.

The second law might be that the numbers of quakes earthwide remain the
same but the numbers of large quakes increases with the increase of the
magnitude, except that as the number of sevee quakes rises the numbers
tend to diminish.

There is a degree of difficulty involved with analysing the second law
as the signals rely on human interpretation and the signals themselves
may interfere with the ones for smaller quakes and mask them.

Perhaps a more expert appraisal of that problem can be supplied by a
rational poster. I still believe there are one or two of them on
sci.geo.earthquakes.

The third law of course, remains that for storms in the Northern Indian
Ocean and East Pacific (the Asian side of it) there is a localising
effect for earthquakes.

More practiced observers will have noted that the warnings posted by
R.Shanmugasundaram (at http://earthquake.itgo.com/today.htm ) also link
to the typhoons and severe storms that occur in his region.

In fact they tend to occur on an arc focussed on his observatory
cutting the sites he predicts.

Hi Michael,

I haven't heard from Shan in awhile. I'm sure he's busy working. Tell
him I said hello when you chat the next time, please. Sorry, I can't
help you with the other bit, it's way beyond me. :-)
