On Tuesday
23rd October on the end of a ramble round the shire post I wondered
in which direction Tropical Storm, potential hurricane, Sandy might take after going over The
Bahamas. The track of very many storms
in the last three years or so has been for most to turn East and diminish to
wet and windy weather in Europe .
But I did
speculate that it might go West and be a bad one, although Florida and The Carolinas seemed the most
likely victims in that case. In the
event it became the Super Storm, a reality as opposed to an unlikely scenario
in a disaster documentary and hit in the place where it would be hardest, New York City .
This could
be the kind of “Black Swan Event”, the description owed to Nassim Nicholas
Taleb in his 2007 book, something unpredicted with extensive and unpredictable
adverse effects.
When the
scale of Sandy became clear, what worried me was
not that the USA
central and local government agencies were unprepared, but that it might be too
big and too complex for any government to deal with successfully.
Clearly
there is now a very big job, or series of jobs, to be done which will be
exceptionally difficult and very costly.
Personally,
this weekend we originally had some family matters in hand involving travel
between the USA and the UK . The arrangements were complicated, but then
six weeks ago I got The Twitch and scrapped the plans to some
disappointment. Just as well, we might
have had a very costly and stressful shambles on our hands.
The trouble
is that The Twitch has not gone away.
Although what the next “bad one” might be is unknown and possibly also
difficult; maybe it is impossible to predict.
The only rationale I have is that bad news seldom comes along as single
items.
Historically,
there is ample evidence for this in all sorts of fields so the thought is
hardly original. In terms of geophysics
alone there is enough to look at. There
was a very big earthquake in the last few days that could have had some serious
effects. Also, Sandy has moved attention away from many
other matters.
So this is
why the picture above is of two Black Swans.
It was taken at Leeds Castle in Kent . In 1321 there was a kind of “Black Swan”
event when Queen Isabella, consort to King Edward II arrived outside the Castle
seeking shelter.
Lady
Badlesmere, born Margaret de Clare (see Wikipedia), left in charge by her
warring husband greeted her and her entourage with a shower of arrows. This led to a siege of the Castle and it
being taken over by Queen Isabella, with Margaret sent to The Tower of London.
The upshot
of this was the Despenser Wars in the Welsh Marches and North of England and
the later putsch by Queen Isabella and the Earl of Mortimer to dethrone King
Edward II.
One effect
in 1328 was the fixing of an intended temporary border between the Norman
French elites in Scotland
and England . We are still trying, without much success, to
sort out the consequences.
After Sandy , therefore, what
happens next and what future may it bring?
Noticed your comment over on Duff's place. He appears was correct in recommending to link over.
ReplyDeleteSandy looked for some period as if it were going to be a problem owing to a stalled high pressure zone over Greenland. Then there was that low pressure area coming down out of Canada. As to the concerns with EQs, yes recent history with those in excess of +7.0 (Richter) do of late seem to be triggering more follow-ons. Hope you don't mind a few links (US centric):

This next is being phased out but it's easier to navigate, the last is the newer version:

Our Cascadia region (Washington state) would seem to be high on the probability list but there're indications of magma exchange in the Salton Sea area of southern California.
