Volcanic explosion or Nuclear explosion? Or?

Was watching a International Space Station or ISS live stream last month, or 10-22-2024 and noticed something very unusual. Would love to hear some thoughts on what this is.

I don’t know what it is, but I don’t think it’s a very recent picture. The same image appears in a paper from the 32nd Annual AIAA/USU Conference on Small Satellites which was held in 2018.

The paper doesn’t say what the feature is, and the photograph was simply being used to demonstrate a new method for attitude determination utilizing color earth images taken with COTS visible light camera [in Development of Attitude Sensor using Deep Learning by Sho Koizumi et al.]

Looks like it might be a volcanic ash cloud, but I can't tell which continent it's from.

Well I was watching what was claiming to be a live stream. Judging by the angle I'd say ISS was probably over Southern California at that time maybe a little further south.
I paused the video to take a screenshot.
I just used Google Earth to take a heads down photo which isn't going to show obviously the same perspective as what's in the screenshot from the video.
I dropped the PIN on the area that's closest to what I believe that was.

hopefully that helps you see that's in Canada.
