Mother Nature always has the last word Preparation will be tested piece by piece or all at once:  Y2K  Annual Flooding  December 2013 Ice Storm  February 2014 Snow Storm  TBD Cascadia Subduction Zone earthquake Test all our systems  Building codes  Scientific designs  Construction techniques  Preparedness efforts 1

What is being done to help me…. I can’t get home due to bridges being closed I am at work when something happens My children are at……. How will my building behave in an earthquake Turn the thinking around: What are you doing to prepare yourself and areas that you can influence? 2

Buildings are built at different times, which means different building codes  Movie theaters  Schools  Houses  Churches Pipes (water, sewer, natural gas) are constructed of different materials at different times Time of Day? Weather? Season? 3

What are you doing to prepare? Your family Your family Your work team Your work team Your business Your business Your community Your community 4

Pay attention to what you do every day and think, “How will I do this if I don’t have……?” Morning routine  Wake up to alarm  Go to bathroom  Make hot beverage  Look inside refrigerator  Read newspaper/e-paper 5

6

Don’t wait for someone to tell you what to do  You have seconds to react  Public agencies respond in minutes to hours  Government responds in days to weeks Centralize planning, decentralized implementation Increase your knowledge 7

Buried soil and fire pits capped by AD 1700 tsunami sand Salmon River, Oregon (Lincoln City area) Source: Soil from forest (black topsoil) occupied by native Americans (fire pits) was struck by a tsunami (tsunami sand) and brought down to intertidal level (tidal mud) by the AD 1700 Cascadia subduction zone earthquake.

 20 earthquakes ruptured all on the subduction zone.  2 to 3 earthquakes ruptured three quarters of subduction zone.  19 earthquakes ruptured the southern half or quarter of the subduction zone. Turbidites show how much of the subduction zone ruptured in ~42 earthquakes over the last 10,000 years. Mw ~9 500 yrs Mw yrs Mw yrs Mw yrs (Modified from Goldfinger et al. (in press) by adding magnitude estimates and some labels) Recurrence

Example: Lincoln City, Oregon (DOGAMI GMS-93) ShakeMaps do not take into account LIQUEFACTION (water-saturated sand or silt turning to quicksand or “quicksilt” during shaking). Liquefaction can cause lateral spreading on even gentle slopes. Heavy objects sink (concrete structures). Light objects rise (fuel tanks). Highest Hazard Intermediate

Liquefaction Earthquake shaking can cause soils to behave like a liquid and lose their ability to support structures magnitude 7.5 Niigata earthquake in Japan

If you feel an earthquake:  Drop, cover and hold Earthquake will seriously delay emergency response.  Strong ground motions for 3 to 5 minutes.  Liquefaction and earthquake force will cause extensive landslides, cutting lifelines  Most bridges will be damaged and damage may not be obvious to a lay observer  Nearly all buildings will be damaged by the earthquake, including those that may be designated as emergency shelters.  Coast will be cut up into “islands” by slides and bridge failure, probably for weeks. KNOW THE RESOURCES IN YOUR ISLAND AND PLAN ACCORDINGLY

» Drop low to the floor ˃You don’t want to be thrown down by the shaking » Seek Cover ˃To protect yourself from falling debris ˃Use the best cover available » Hold On to the Cover ˃The shaking may cause the cover to “walk” around. Stay with it!

A little bit of preparedness goes a long way! Questions? 36 The OSU Press has made the online version of this book available to the general public without charge. uake/index.html uake/index.html The book contains the information about how to upgrade your house against earthquakes, including the interior, organizing a preparedness kit, earthquake insurance, in addition to chapters on the subduction zone, crustal faults, etc.
