[Hajo Neis, see official 2014 report for Oregon Office of Emergency Management at http://www.oregon.gov/OMD/OEM/pages/plans_train/tsunamis.aspx#Tsunami_Evacuation_Wayfinding]

Oregon:  subject to tsunami

Normally work just on pattern language in architecture

  • Wanted to work across disciplines

Tsunami is a series of waves

Video:  destruction unfolding

  • Scale of 300 km

Triple disaster

  • 1. Earthquake
  • 2. Tsunami
  • 3. Nuclear disaster (man made)

Tohuku City

2013 Tamura City, Architecture Institute of Japan, International and Urban Design Workshop

  • 20 km zone
  • Smaller zone, but couldn’t sleep there at night
  • If more than 10 m high, survived; otherwise killed

Started some studios on Regenerative Design

Post Tsunami Community Redevelopment, Chennai, India

Fury and Fragility, Nadia Koska, developed an infrastructure design

Survival Language Pattern Language, Tomoki Furukawazono

In June 2015, within 24 hours, had 7 earthquakes in the Pacific Ocean just off Oregon coast, at 5 and 6 Richter scale

  • A Richter 7, get tsunami

[Perrin Wright]

Tsunami is caused by earthquakes

  • Magnitude and location determine shape of wave

60 mile Cascadia Subduction Zone

  • 4-7 minutes of aftershock, then 18-22 minutes before tsunami

Wayfinding is the process of determining and following a path or route

  • 18 to 22 minutes later with no roads, no signs

Study site:  Cannon Beach

Evacuation route signs

Tried at night

Phase 1:  A Survival Language (from Iba’s work)

Before, during, and after:  Preparation, evacuation, response

Have been trying two routes with two cities

Want to find a Wayfinding Chain

  • Creating universal signs
