Hi John, mind if I pick your brain for a bit?
So here is the tremor map from the 7th -11th of this month; before the double Mag 8's across the globe:
And here is the map from the past 2 days:

Now, I see that the activity is not up to the level of the earlier "swarm", but maybe it is building?
If I'm learning to interpret the spectrograms correctly, it looks as if the tremor is continuing as I type. Maybe even expanding into southern
Oregon. I base this on my purely self-taught correlation of these faint
, between 2 and 7 Hz, and tremor noted on the map the next day---so scientific.
(Watch, it will turn out to be electrical
transmission difficulties, and I will be back at square one again.)
While on my internet rounds of earthquake and volcano data, I came across this small sulfur dioxide concentration just near Medicine Lake in northern
California. And another well east of Mt. Lassen. NASA SO2

Is it posssible for tremor to release gases? Um, is possible for the tremor to "excite" nearby volcanoes into releasing gases?
In the past year of sporadically checking the above site, I've never seen such a concentration. I've checked the US Forest Service site in Modoc, no
prescribed burns are going on. And Medicine Lake has only had 6 tiny earthquakes in the past month. I just thought it was curious.
Is there access to Japan's tremor monitoring data, to see if it also showed fault wide activity before the big quakes on April 11th? Maybe the whole
of the earth was agitated, and that plate bore the brunt of it.
Lastly, good luck on your presentation tomorrow. Any chance it will be filmed?
