It should be on here: http://www.volcano.si.edu/reports/usgs/index.cfm?content=archive
in about 12 hours from my posting.
If you are interested, compare the low seismicity for the times of
eruptions at: http://neic.usgs.gov/neis/qed/
And the state of "oscillation" at an ocean near you.
The North Atlantic Oscillation is negative when there is a low
likelihood of large magnitude quakes and an high likelihood of
volcanic eruptions. (I have not prepared a datum or cut off point. My
ideas are based on the original concept of the climatologist who
noticed the phenomenon, not on the seasonal averages posted for
winters on meteorological office sites.)
The north Atlantic sea level pressures for any date back to 1998 can
be seen here: http://www.wetterzentrale.de/topkarten/tkfaxbraar.htm
Your post was about a phenomenon that occurred on 18th-19th Sept 2007.
On the 17th it was remarkably positive, with an Azores High of 1035
and a set of Lows above it between 980 and 989.
On the 18th the lows had climbed a few millibars. Things look a bit
different on the 19th but still very much a +ve. Back to the drawing
board?
Maybe; but look at the European pressures on there.
And check out the ocean near you at BOM: http://www.bom.gov.au/nmoc/MSL/
(It doesn't look like they have archives of the sea level pressures,
perhaps you could work on the upper levels (they give jet streams) but
it's all geek to me, I'm afraid.) |
