I was looking through the ShakeNet app, and comparing it to my Helicorder seismograms. I couldn’t find the one at 9:16 in the app, and it went on for a few minutes. It looks like a distant earthquake due to the length of the movement of it.
Are there any ideas why I couldn’t find the event? Based on the timing, I think it’s a 6.9 magnitude earthquake near Alaska as reported on the USGS website.
