In my opinion, the "Big One" would cause more damage than the eruption of Mt. Rainier. When you have an earthquake houses and buildings can collapse and tsunamis can happen. People can be left homeless, property would be destroyed, many things can be lost and people could drown from the tsunami. Mt. Rainier would just cause flooding from winter storms, but if there were an earthquake, you would get the damage caused by the earthquake and flooding.
When convection current breaks up brittle rock that makes up the crust, it forms plates. The plates are moved around on earth's surface which is caused by the currents of magma. When this happens, it creates landscapes like mountains and plateaus because as the plates move around, they grind, scrape and fold against each other.
