This is from two indoor BMP280 sensors on Home Assistant that are about 5300 miles from Tonga. (They are a floor apart from each other)

It's amazing what extremely cheap sensors can currently measure, though 1883 technology was sufficient to measure the pressure wave from Krakatoa circling the globe multiple times.
