What is Intensity and the Mercalli Intensity Scale?

The amount of shaking that occurs on the surface due to an earthquake is called the intensity. It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,…IX, X, and often displayed with color codes ranging from light blue to dark red.
Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.

Earthquake statistics

Average number of earthquakes

Based on data from the past 54 years and our earthquake archive back to 1900, there are about 27.2 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):

  • Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 62.5 years)
  • Mag. 6 or higher: 0.02 quakes per year (or 1 quake every 41.7 years)
  • Mag. 5 or higher: 0.02 quakes per year (or 1 quake every 41.7 years)
  • Mag. 4 or higher: 0.31 quakes per year (or 1 quake every 3.2 years)
  • Mag. 3 or higher: 4.8 quakes per year
  • Mag. 2 or higher: 15.9 quakes per year
  • Mag. 1 or higher: 26.8 quakes per year

The area where this quake occurred has a high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.
