[Geoldept] Air pressure wave from Tonga volcano

[Susan DeBari]

This is from Dave Hooper, who found that he could discern the Tonga air pressure wave in his atmospheric pressure sensor out in Lynden. See ~4:30 am!

I happened to be out sampling on Saturday morning with students Savanna Dayton and Cara Gutenberg, shortly after hearing about the eruption of the Hunga Tonga volcano, and that it’s pressure wave circled the globe. Turns out we recorded it on our atmospheric pressure transducer at Kamm Creek. We’re only recording averages once every 15 min, and this is ~10 hours of data from that morning; but check out the spike at 4:30 am (right when predicted)!
