Most of the quakes register at 10km.
You’ll be told that the USGS uses this as a default number.
That holds up until you realise that their equipment can pinpoint genuine earthquakes at depths over 500km.
Either the DUMB theory is right or the USGS is calling it in 75% of the time.
What I haven’t read anywhere is how come the Tonga ‘ volcano ‘ registered around 5.5 to 6 but images exist of a huge type of fallout cloud as a result.
Every week there are scores of earthquakes of 5 to 6 on richter but I’ve only seen an after event cloud once before.
In 2011 when Fukushima was hit by a 9 pictures showed a distorted cloud rising above the power plant

Richter scale means that a 6.1 is twice that of 6 so following this through the Tonga event was either off the scale and is being underplayed or the cloud etc may be some form of CGI
This might be the most detailed article from the time. The fireball is tiny in relation to Tonga.There used to be images of the sound wave bubble on line.
