Perhaps changed radio wave propagation too? https://dr2w.de/dx-propagation/ https://dr2w.de/dx-propagation/

  I'm not sure what that link is showing. And what mechanism would you propose?

    In long distance rf communication, radio waves are bounced (sometimes several times) off different regions in the ionosphere (https://www.electronics-notes.com/articles/antennas-propagation/ionospheric/hf-propagation-basics.php https://www.electronics-notes.com/articles/antennas-propagat...). Since the waves caused by the eruption apparently reached the ionosphere, (some) radio bands may be affected.

      OK, that much I knew. Does the site show actual range / attenuation at the time of / following the Tonga Hunga erruption?
