When six-year old Suzunosuke felt the earthquake he remembered from lessons at school that there were was a risk that a tsunami would follow. He immediately alerted his father to that risk and, heeding the warning, his father gathered up the family and ran up the hill to safety. Hundreds died in Onagawa, but Suzunosuke's family survived because he knew the dangers and what action to take.

Now here is a lesson from a six year old:
Be prepared, take precautions, do not deny that it is happening, run up the hill or taken in another context, cut carbon emissions, just in case.
This is for the trolls.
