What is the highest rating on the Mercalli Scale and what are the symptoms of an earthquake of this intensity?
The Modified Mercalli intensity scale ranges from 1 to 12 (I - XII), with XII being described as cataclysmic. This leads to total destruction of nearly all structures. The ground surface will potentially have permanently changed level by several metres. The ground's surface moves with visible waves or ripples while the earthquake is occurring.
What is the scale earthquakes are measured on?
The Mercalli scale.
What is the difference between the Mercalli scale the Richter scale and the magnitude scale?
In seismology (the study of seismic waves or vibrations in the ground / earthquakes) the Richter scale is a magnitude scale. Magnitude scales show the amount of energy released by an earthquake. In the case of the Richter magnitude this is based on the amplitude of the seismic waves measured on a seismometer and the distance of the seismometer station from the epicentre of the earthquake. The magnitude value should be the same for a given earthquake no matter where it is recorded. The Mercalli scale is an intensity scale. This gives information on the perceived ground shaking in a specific location. The value is derived from witness reports on the perceived violence of the shaking, from the damage done to buildings and other infrastructure and also based on measurements from accelerometers and other seismic recording instruments in order to make the Mercalli intensity value a less subjective parameter. The intensity and damage to infrastructure can be influenced strongly by a number of variables including local ground conditions and the use (or otherwise) of earthquake resistant design.

How does the mercalli scale measure earthquakes?
The Mercalli scale allocates a value to an earthquake based on the perceived shaking in a specific area as well as the damage to buildings and infrastructure that has occurred. The US Geological survey also use data based on the amplitudes of seismic waves and surface accelerations as measured on seismometers to quantify "perceived shaking".
