2011 Virginia earthquake
The USGS found that the farthest landslide from the 2011 Virginia earthquake was from the epicenter. This is by far the greatest landslide distance recorded from any other earthquake of similar magnitude. Previous studies of worldwide earthquakes indicated that landslides occurred no farther than from the epicenter of a magnitude 5.8 earthquake. The study suggested that the added information about East Coast earthquakes may prompt a revision of equations that predict ground shaking. "What makes this new study so unique is that it provides direct observational evidence from the largest earthquake to occur in more than 100 years in the eastern U.S. Now that we know more about the power of East Coast earthquakes, equations that predict ground shaking might need to be revised."
Earthquakes in Western Australia
Gabalong, 30 August 1955, magnitude 5.8 Gabalong, a small community about 30 km east of Moora and 200 km NNE of Perth. The earthquake, at 9.52 pm local time, was felt at MM VI at Yericoin and Miling, and MM V in Moora. It was felt in Perth at intensities between MM II and MM IV, and at Dongara at MM II. 
It was preceded by a magnitude 5.3 earthquake at the same location at 2.09 pm on the same day. It was a SouthWest Seismic Zone earthquake, and because of the poor location capabilities at the time, may well be related to a series of earthquakes near Yericoin, which started with a magnitude 5.1 earthquake on 2 May 1949.
