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."
Courtenay, British Columbia
On 14 June 1946, a 7.3 magnitude earthquake struck just west of Courtenay, with the epicentre located at Forbidden Plateau. The earthquake was felt as far north as Prince Rupert and as far south as Portland, Oregon. Many of the town's chimneys were destroyed, and there was significant damage to the post office and the Courtenay elementary school. This was the largest earthquake to hit Vancouver Island, and the largest onshore earthquake in Canada on record. There were only two reported deaths: one Seattle man died of a heart attack and another drowned when his boat capsized due to a resulting wave.
