What happened in Turkey made me think carefully about how to keep my cold storage wallet seeds.

I keep them in a waterproof and fireproof notebook, but is there any proof of the efficiency of this Metal Seeds and/or notebooks with earthquakes? Does it bear the violent shocks?
What are the solutions, in your opinion, if an earthquake occurs? Or in other words, the best solution if you are in an area active in earthquakes and tsunamis.
