7.8 would be described as 'major'. Damage to most or all buildings. Death toll could be considerable
The Richter scale is used to measure the magnitude of earthquakes. It is a logarithmic scale, meaning each whole number increase represents a tenfold increase in amplitude. For example, an earthquake measuring 7.0 on the Richter scale is ten times larger in amplitude than one measuring 6.0.
The magnitude of the 2010 Haiti earthquake on the Richter scale was 7.0
The Richter scale is logarithmic, meaning each whole number increase represents a tenfold increase in measured amplitude. Therefore, an earthquake measuring 5.4 on the Richter scale has an amplitude that is 10 times greater than that of a 4.4 magnitude earthquake. The difference of 1.0 on the scale indicates a tenfold increase in amplitude. Thus, the increase in wave amplitude from a 4.4 to a 5.4 magnitude earthquake is a factor of 10.
Earthquakes are measured using the Richter Scale, Moment Magnitude Scale, or the Modified Mercalli Intensity Scale. These scales take into account characteristics of the seismic waves and the effects of the earthquake on structures and the environment to determine its magnitude and intensity.
The Haiti earthquake was measued at a magnitude of seven on the ricter scale.
The richter scale!
An earthquake measuring between 7.0 and 7.9 on the Richter scale is considered a major earthquake. It can cause serious damage to buildings and infrastructure in populated areas, potentially leading to injuries and casualties. Such earthquakes may also trigger tsunamis in coastal regions.

The 2004 Indian Ocean Earthquake measuring 9.3 on the Richter scale. The strongest was in Japan measuring 9.5
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
An earthquake measuring 5.4 on the Richter scale would have 10 times higher wave amplitude compared to one measuring 4.4. The Richter scale is logarithmic, so each whole number increase corresponds to a 10-fold increase in amplitude.

The Richter scale is used to measure the magnitude of earthquakes. It is a logarithmic scale, meaning each whole number increase represents a tenfold increase in amplitude. For example, an earthquake measuring 7.0 on the Richter scale is ten times larger in amplitude than one measuring 6.0.
Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.
The magnitude of the 2010 Haiti earthquake on the Richter scale was 7.0
The 2011 earthquake was a 5.8 magnitude on the Richter scale.
