The next large earthquake aught to be Japan.

However there have been few large quakes there in the last weeks
despite all the High Pressure over Britain and Western Europe.

Today (23rd March 2012) with everyone on uk.sci.weather moaning about
how nice it is and how nobody told them about fog and all the rest of
it (comparative drought conditions) I though it might be an idea to
get set for the Japanese quake.

Since the region is blocked we aught to be getting some tropical
cyclones. So far there are none showing.

Last year around this time of year there were notifications of
depressions, storms and cyclones between February 1 and April 30 in 11
basins:

South Atlantic - 14 March.
South Indian - 9, 11, 15, 16 Feb, 17 March, 2 and 15 April.
South Pacific - 18 and 13 February.
West Pacific - 2 April.

I don't imagine it would be a good idea to expect a cyclone in the
South Atlantic to warn us of the next severe Japanese earthquake. But
it WAS the only one just before the Fukushima business.

There are 9 known events in that region according the Wikipedia:

Subtropical Cyclone 17 March 1974
Angola Tropical Storm 10 1991
Tropical Cyclone 18 January 2004
Cyclone Catarina 28 March 2004
Tropical Storm 21 February 2006
Subtropical Storm 28 January 2009
Tropical Storm Anita 8 March 2010
Subtropical Storm 16 November 2010
Subtropical Storm Arani 14 March 2011

So they are not completely unknown.
What I remember of events around that time was an eruption in Iceland
and a severe storm in the far north off Norway.

This week, the MetOffice is indicating a lot of volcanic activity:

I'll put some of the charts on an album and a thread in my blog.
I can't think of anything more off hand.
More later.
