E. I think that the "Big One" would be more devastating. Imagine having everything crumble to the ground right before your eyes, it would be hard to overcome the damage, or even survive. A big volcanic eruption would be difficult to bounce back from, but Centralia is far enough away and would only be covered by ash. Both the "Big One" and a big eruption are due for our area, but survival from an earthquake is a bigger problem than five inches of ash. Catastrophes like those are so large, even if they started in the Puget Sound area, people in Centralia could still expect damage.
C. I think that the Polson Ice Lobe had the most impact on Washington's landscape. It blocked lakes in Montana, Idaho, and Washington. The rivers water was stuck and eventually the glacier melted and made one big glacial lake. The lake was the size of Lake Eerie and Lake Ontario combined. This ice lobe has had a major impact in a big mass of water in Washinngton.
