Quizplus · Accepted Answer

The likelihood of an M 8.0 earthquake or a Mercalli XII earthquake is extremely low. A 2014 study found that there is an average of only one earthquake with a magnitude of 8.0 or higher per year globally. Mercalli XII earthquakes are even rarer, as they represent the highest level of earthquake intensity and are associated with almost complete destruction. Therefore, the expected number of M 8.0 or Mercalli XII earthquakes per year is very low- only one.
