Tuned Mass Damper of Taipei 101

You are confusing two different units. The earthquake moment magnitude scale measures the amount of energy of a given earthquake. It does not concern the location you are and the shacking you felt. Therefore, for this particular Taiwan earthquake, its magnitude is 6.9 regardless of the location.

The intensity scale on the other hand measures the amount of shaking for a given location. Naturally, the further you are from the epicenter, the lower the intensity will be.

Thank you, this is good! :P :) xx ;p

It's quite confusing to have a couple of different numbers to "characterize" a quake: magnitude (in a few different systems), intensity scale (guess there are different systems around the world as well).

Really great to see the clarity here from knowledgable people on this! :) ;pxx ;p
