19th-20th July 2012. …
This annimation covers Wednesday to Saturday the 18th to 21st July 2012.
There is a strange or unusual at least, set up on here on Thursday and Friday.
All around the continent the isobars stretch to an almost unbroken circle. If they were standing off somewhat leaving a gap on the shoreline, Iwould say it is a massive storm brewing. But the isobars even cross into the continent just before the Antarctic Peninsula at about 160 west.
At this longitude, a severe earthquake event takes place.
Is this the volcanic eruption of the year?
I confess to expecting one, but I only have blind guesswork or fancy to go on. That and the wet weather and lack of a severe volcanic display for a few weeks.
