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."
Earthquake (1974 film)
Other deleted scenes were shot to wrap up many characters' stories after the earthquake. Walt Russell and Dr. Stockle – whose fates are undetermined after the quake in the theatrical release – were shown alive in the seismology laboratory post-quake. They were shown finding the earthquake's magnitude to be 9.9 on the Richter scale. The film's final scene originally had Denise asking Lou Slade if Stewart had survived; upon hearing of his death, she walks over to Corry who has regained consciousness.
