Note:

The electron graphs I am following have remained below the median line, but are basically level except for slight bends in the graph at 6 PM on 12/28, around 10 AM on 12/29 and 8 AM on 12/30.
Red Puma reports 6M quakes, in the region of Hokkaido/Kuriles at (latest first):

30Dec2003 09:50:53.5 49.8N 155.6E 10 mb=6.3 M*SED KURIL ISLANDS 1102

29Dec2003 11:48:43.0 22.6S 169.7E 10 M =5.8 M*NEI LOYALTY ISLANDS REGION 1537

29Dec2003 01:31:03.7 45.7N 146.6E 10 MS=6.4 M*SED KURIL ISLANDS 1202

Only the greatest magnitude quake in a group is shown, and all lesser quakes are edited out.

The noted relationship continues to hold, and it doesn't seem to require more than a minor change in the electron flux for a correlation.
