Ancient Japanese Standing Stones Were Primitive Tsunami Warning System

Fascinating story here a several hundred years old set of stone markers along the Japanese coast was a set of instructions on how to avoid the dangers of a Tsunami following an earthquake. The markers contained such valuable information as "remember a Tsunami follows an Earthquake, chose life over possessions and run." One town, in fact, suffered little damage, because rather than rely on sea walls they built on the high ground designated as safe by the local stone monument.
