Could a 9.0+ earthquake from the Cascadia Subduction Zone trigger an eruption of Mt. Rainier?

I have read that CSZ has the potential to generate a megathrust earthquake (>9.0). Rainier is an active volcano fairly close to this spot. I imagine if both these events occurred simultaneously it would cause some serious havoc.

The primary danger with Mount Rainier isn't an eruption, but rather that the mountain isn't "solid." The mountain's interior is a soft clay which has been formed by the active hydrothermal system underneath and freezing/thawing expansion/contraction of it's 25 glaciers on top. Thus, the major threat is from the collapse of a portion of the mountain itself into lahars -- basically a huge mudslide that wipes out everything in it's path.
