The earthquake which hit Newcastle on 28 December 1989 measured 5.6 on the Richter scale. Effects of the quake were felt throughout central-eastern New South Wales. There were reports of damage to buildings in Scone, Gladstone and Sydney, the latter some 800km away. The shaking was even felt in tall buildings, in places over 5000km away.

The Mercalli intensity scale would be most appropriate for describing historic earthquakes where seismograph records are not available. This scale categorizes earthquakes based on the observed effects on people, buildings, and the environment rather than on instrumental measurements. It provides a qualitative description of the earthquake's intensity and impact.
Richter scale, Modified Mercalli scale, Centigrade scale, and the Moment Magnitude scale
Richter scale is used to measure earthquakes magnitude Shake intensity is measured on the Mercalli scale
The Modified Mercalli Intensity (MMI) scale measures earthquakes based on the level of damage and the effects felt by people and structures. The scale ranges from I (least amount of damage) to XII (total destruction).

considerable damage
the modified mercalli scale was VII-VIII
modified mercalli scale measure is type of seismograph that they made in the 1989
The Rickter (RICK-tur) scale has been popular for decades to measure the intensity of earthquakes, yet it had its issues. These days the Mercalli scale is most often used by geologists and vulcanologists.
Yes, the Modified Mercalli Intensity (MMI) scale is still used today to measure the intensity of earthquakes based on observed effects on people, buildings, and the environment. It provides a valuable complement to seismic magnitude scales in assessing the impact of earthquakes on society.

It provides a qualitative description of the earthquake's intensity and impact.
The scale used to classify and describe the effects of earthquakes on structures and local damage conditions is the Modified Mercalli Intensity (MMI) scale. This scale ranges from I (not felt) to XII (total destruction) and assesses the level of shaking and resulting damage experienced at a specific location during an earthquake.
The Modified Mercalli Intensity scale is used to measure the intensity of an earthquake based on its observed effects on people, buildings, and the natural environment rather than the seismic energy. It provides a qualitative assessment of the shaking and damage caused by an earthquake at a specific location.
