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."

In the past, there have been several tsunamis in the British Columbia area. Two, occurring in 1700 and 1946, were caused by earthquakes and never hit the shore. Three tsunamis did make landfall. One struck in 1960, and was caused by a magnitude 9.5 quake. It affected the town of Tofino by damaging the local log booms. The next, in 1964, was caused by a magnitude 8.5 earthquake and produced a 14-foot wave that completely flooded parts of the towns Hot Springs Cove, Bamfield, and Port Alberni. The wave was traveling over 435 mph and caused about 8 million dollars in damage. The last tsunami, in 1975, was caused by an undersea landslide and occurred in the Kitimat Inlet of the Douglas Channel.
