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.

Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.
[More info]

What about this quake?


Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface of approx. 1,259 km2 (=486 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 61 km (38 mi).
