The one that might happen is the Canary Island fault, where a huge chunk of land will subside into the Atlantic ocean, creating a displacement tsunami, as opposed to the uplift/downlift one in the article.
A displacement tsunami, as it is named, will displace the same amount of water as the land the falls into the ocean to create it. Unlike the uplift tsunami, which goes until it hits shallow water before breaking, this kind creates a standing wave on the surface that travels until it hits land at the same height. The one in the article would flood cities like Seattle. A displacement tsunami would role over all East coast cities, until it broke against the Appalachian/Allegani mountains. It is assumed the wave would travel at close to 300-600 mph.
Look up Latuya Bay, Alaska where there was one of these waves in the 1950s.
