Tonga Volcano Eruption
« on: January 19, 2022, 08:39:34 AM »
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.

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

I got this image from an acquaintance with contacts in the Australian Bureau of Meteorology.

I also have a friend who is involved an agricultural mesonet and he measured the propagation across that network confirming that the anomaly was travelling at the speed of sound.

A neat visualisation in the middle of this video showing the pressure wave moving across weather stations in Japan and USA:

Mine recorded both the initial shockwave and the aftershock
