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."
2016 Te Araroa earthquake
Following the earthquake, the Ministry of Civil Defence & Emergency Management (MCDEM) issued a tsunami warning for parts of the north and east coasts of the North Island. Waves measuring 30 cm in height were recorded by tide gauges at East Cape and Great Barrier Island, and although the warning was later cancelled advisories remained in place for strong currents and abnormal sea level fluctuations.
