Tonga Volcano Eruption

(1/2) > >>

The NWS in Chicago reported that the Tonga eruption caused a spike in air pressure that was recorded around 8:20 am CST on Saturday morning (1/15/22). A second wave from the east arrived in the Chicago area on Sunday morning. I checked my WS2902 and, of course, it's not sensitive enough to show anything. Just wondering if anyone else was able to record either reading.

This is from Boulder:

I only saw one in Ontario Canada.

My WS-2000 showed a little blip right at 8:20 AM. [ You are not allowed to view attachments ]
