Survey of Damage from Japan’s March 11th Earthquake and Tsunami, presentation by Kit Miyamoto

A colleague forwarded a link to a very interesting presentation by a Japanese engineer who surveyed the earthquake damage at various locations along the coast. It contains a lot more engineering information than all of the media reports I have seen.

Some interesting notes:

  • Strong shaking does not seem to have caused much if any structural damage. Tsunami damage was the dominant event.
  • Some types of construction (steel, concrete) resisted the tsunami better than others (wood).
  • He estimates that Tsunami warning systems that were in place saved hundreds of thousands of lives.

Here’s the link:
