M6.8 and 6.5 Cascadia USA strike-slip quakes - Island Chris - 10-22-2018
There was a M6.5 and 6.8 strike-slip quakes near the northern part of Cascadia, but towards the west side of the Juan de Fuca plate or a related small plate). Probably has little effect on the Cascadia subduction zone. I'll have to look late which nodal plane it is to see if it might tweak the subduction zone a tiny bit.

The following SWPC images depict how the electron flux was behaving, before and during the 6.5+ Port Hardy events.

The time of the quakes is certainly coincident with the strong activity in the second graph.
The question is, are they related. That's the hard thing to answer.

Yes, I would have to agree. The data leaves the question open to speculation, and without a definitive correlation to the actual event location, it can only be regarded as coincidental.

So far no hits on your prediction list.

True... can't seem to get a grip on this during solar minimum.
Are you still going to be doing this in 6.5 years ?
Why are we in Earth Sciences ?

No worries Duffy but it's not a job, it's a hobby and no I won't be doing it in 6.5 years.
I'm 84 now so in a few more years I'll be feeding the worms.

Hi Roger,
My post about Cascadia is from 2018. I made a post under Miscellaneous a couple of weeks ago. I'll try to post once in a while but because of Covid-19 I'm probably getting 3 times as much email traffic and I'm checking out how friends and family are doing.
