That would be a "kind of strong" earthquake but 8+ is huge.
Richter scales are used to measure the magnitude of an earthquake. There is no specific unit used for earthquakes. I hope this helps. =)
Magnitude is a term used to describe how much energy was released by an earthquake. It gives an indication of the amplitude of the seismic waves that occur and also on the length of the fault rupture zone and the displacement along the fault. A magnitude 7 earthquake is defined by the US Geological Survey as a "major" earthquake. In general earthquake over a magnitude of 4 or 5 can cause damage although the exact reasons why some earthquake are more damaging than others is more complext than just the absolute magnitdue of the earthquake. For more information on this, see the related question.

a Richter scale
Scientists measure the magnitude (energy) of an earthquake using a seismograph (sort of sensitive pendulum that records the shaking of the earth).
The word used to describe the amount of energy released by an earthquake is "magnitude." This is typically measured using the Richter scale or the moment magnitude scale.
The size of an earthquake is defined by its magnitude. Magnitude is a measure of the energy released at the earthquake's source and is typically reported using the Richter scale or the moment magnitude scale.
The moment magnitude scale has replaced the Richter Scale.
The energy is known in Joules and it can be compared to the explosive energy of TNT.
measurement of the amplitude of the largest seismic waves
Depends on it's magnitude which can range. Seisometers are used to measure the Magnitude of an earthquake. Magnitude is it's strength.
The word Magnitude is used to described the amount of energy released when an Earthquake occurs
The Seismograph is used to measure the Magnitude of an earthquake.
Richter Magnitude
The Richter magnitude scale is used to measure the strength of an earthquake.
The scale used to describe the strength of earthquakes is the Richter scale, which quantifies the energy released by an earthquake based on the amplitude of seismic waves. Another commonly used scale is the moment magnitude scale, which provides a more accurate measurement of an earthquake's size by considering the seismic moment.
