  1. Geotechnical Engineering Research Ideas Cascadia Working Group 05/15/2012

  2. Cascadia Shakeout Scenario • Potential SoCal EQ • Seismology • Structural • Geotechnical • Lifelines • Social • Public Policy • (Tsunami)

  3. Subduction Motion Prediction Models • Long-duration codas • Long-period (high-frequency) • NEED database of subduction zone events • Secondary need: synthetic earthquake motions to “fill out” database

  4. Soil-fluid-structure interaction • Mainshock -> Tsunami -> Aftershocks • Instability • Tsunami structures • Seawalls • Critical Coastal Infrastructure

  5. Silt Liquefaction • Willamette Valley silts • Portland Hills silts • NOT sure how these silts will respond to the Cascadia event (or ordinary earthquake motion)

  6. Site Response • What will CSZ earthquake motion be when it reaches WV population centers?

  7. Coastal & Cascadia Landslides • Identifying landslides • Landslide hazard mapping • Large landslides • Instability after shaking ceases
