    May I ask a content question as well? Is the difference between 震度 and マグニチュード is that magnitude measures the strength of the seismic event while 震度 is more what ot feels like where you are (and allows you to characterize that by reference to the illustration). The diagram remnds me of the Beaufort scale for wind and maybe serves much the same purpose in helping to stardize what people mean when they say terms like “strong”. Enjoy Golden Week!

    https://en.m.wikipedia.org/wiki/Seismic_scale answer my question!

      Yes, you are right. Magnitude measures the total power of the earthquake–not the shaking it causes at each location. A relatively small earthquake can have a high shindo near its epicenter if it is near the surface and the ground is soft. For example a tornado can be very powerful and dangerous at its focus, but in its total energy it is very small compared to a hurricane or a typhoon. Shindo gives us a better picture of how damaging an earthquake is.

      Thanks for the article. It will help other readers as well.

        Oh dear – “answer my question!” looks very rude. I meant to say that the article answers my question (although you answer added to it). I am sorty for my typo and the impression it may have given. Stardize should also have been standardize. My Japanese has even more mistakes and I am sure I have often been rude unintentionally. もし訳ありません.

          No problem! I did not think it was rude at all. Have a nice evening!

        Great! I am glad to hear you got it cleared up. I just checked it on a computer and my iPhone without finding anything and was just about to tell you to refresh your browser. Any time you have a problem don’t hesitate to ask.

        You’re welcome. It seems to happen on iPads sometimes, I’ve noticed.
