Tsunami stones

Martin Fackler for the NY Times in 2011:

While some are so old that the characters are worn away, most were erected about a century ago after two deadly tsunamis here, including one in 1896 that killed 22,000 people. Many carry simple warnings to drop everything and seek higher ground after a strong earthquake. Others provide grim reminders of the waves’ destructive force by listing past death tolls or marking mass graves.

I think we need to have more of these types of stones for other types of disasters and we should enforce their being heeded.
