This year has been crazy for me and my hobby to record earthquakes. Just
in May, June, July and what has passed of August I estimate that I have
already recorded as many earthquakes as I did in whole of 2007.
The most active areas this year have been Sisz and Tfz. At this moment I
have massive backlog of earthquakes to plot. I am not sure that I am
never going to finish it, as the data might not even appear on IMO web
I have also been hit by one problem, because of the large volume of
earthquakes I have recored I don't have the time to email all the events
to the event list. But I try to send what I can, but it is far less then
I want to.
I am expecting more earthquakes for the remainder of this year. With TFZ
being the most active part of Iceland, if nothing changes that is.
I also want to point out this email that I got yesterday.
=EF=BB=BFThe August 7-8 eruption of Kasatochi volcano (Aleutian Islands)
produced a very large stratospheric SO2 cloud - possibly the largest
since the August 1991 eruption of Hudson (Chile). Preliminary SO2 mass
calculations using Ozone Monitoring Instrument (OMI) data suggest a
total SO2 burden of ~1.5 Tg. This figure will be revised in the coming
weeks but is more likely to go up than down. The SO2 cloud has drifted
over a large area of North America and is now (August 14) reaching
This is also a request to anyone with ground-based instrumentation
(DOAS, FTIR, lidar etc.) who may be able to make observations of this
cloud. The location of the SO2 can be tracked using these near-real
time SO2 websites:
If anyone needs any more localized maps of the SO2 plume, please let me
The effects of this are going to be felt for a long time.
