Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

You're right. 1952 Severo-Kurilsk

Almost the same spot too. 15-18m tsunami waves, three of them.

I don't know if the depth of it was different, or since it's a logarithmic scale it was just that much weaker, but Russia reported 10-12ft tsunami waves (which is admittedly way too much) Japan reported 2ft, and California got between 2ft and 5ft.

Probably had more to do with the direction the plates shifted rather than total energy of the shift I guess

Yeah, I imagine even a 1ft tidal wave would be enough to sweep a person or a small car away.

Apparently, there are a whole mess of magnitude scales. The 8.8 and 9.0 are given in "Mw" scale,which estimates total energy. It doesn't differentiate between friction and the seismic wave energies.
