Decisions and Preparation

The Earth is Like a Lava Lamp

Hot Cold

Faults Pressure Created Crumples in the Crust That are Weakness—as pressure builds, The Crumples are the easiest places to Release Pressure Builds and Creates Faults— Areas in the ground that crumpled and bent Once crumpled, the creases (faults) are where the ground is most likely to move again when pressure builds up enough.

Here’s where we know the earth has crumpled and creased in the Seattle area. There are also faults deep under ground that we can’t see.

The ground we walk on Soil Types Rock Rock/Water/etc

Rock/Water/etc

A lot of soil in Seattle is more similar to red dean pudding than rock—and when shaken, can act more like water that stone

Hard earned success led to the demand for impressive buildings

Everyone was building bigger, Building stronger

Unfortunately: almost the worst building type for earthquake resistance 大丈夫能屈能伸 For Earthquakes: Buildings are like people—flexible is better

Best: low, wood --Bolted to Foundation

OK: Steel and reinforced concrete:

Bad for Quakes: Soft Structures

Worst for earthquakes Worst: Un-reinforced brick (recognized by levels of brick ends) Not very good: reinforced bricks (recognized when all bricks show their sides) Not very good: Retrofitted masonry (recognized by the added bolts) 5 out of 6 were damaged during the 2001 Nisqually Quake

Unreinforced Masonry

Options Retrofit Anchor masonry to wood Add Framing Still will be risks Rebuild Create a new safer building Lose character and feeling of history Relocate Currently located in one of the most dangerous parts of the city Lose character and history
