Rokuyo survey

On this page we'll see how well Rokuyo performed on days of major disasters that have hit the world.

These include earthquakes, tsunami, floods, typhoons/cyclones/hurricanes, extreme heat, and other events which have resulted in tens or hundreds of thousands of deaths, and often suffering for millions of survivors.

However, these events usually build up over several days, so aligning them to a specific Rokuyo day is not possible. A notable exception is an earthquake, and the timing of those are quite precise.

So for this survey, we list the major earthquakes from the start of this century. Also for this survey, we've changed the term "bad luck" to "misfortue" which seems more appropriate.

(Incidentally, we refrain from calling earthquake "natural disasters" because...)

Background

Rokuyo is quite balanced, which is what you'd expect from this yin-yang system.

It has an equal amount of  good fortune  and  misfortune,  as shown in the Fortune Indicator below.

Conclusion

For Rokuyo to succeed, the earthquakes should always happen on the misfortune part of the Fortune Indicator bar, but the above chart shows this is not the case. Of the eleven earthquakes, only three were on the misfortune part.
