According to the US Geological survey, the maximum intensity of the magnitude 9.5 Chilean earthquake of 1960 was rated as XI on the Modified Mercalli Intensity scale which are described as very disastrous or extreme events which are likely to cause significant damage to structures.

An earthquake with an intensity level of XII on the Modified Mercalli Intensity scale can cause total destruction in the affected area. Buildings, bridges, and infrastructure may collapse, resulting in widespread devastation. There may also be landslides, ground ruptures, and tsunamis triggered by such a powerful earthquake.
The Modified Mercalli Intensity (MMI) scale is typically used to assess the level of earthquake damage to homes and other buildings. The scale assigns a value based on observed effects and is used to quantify the intensity of shaking at a specific location during an earthquake.
The amount of shaking produced by an earthquake at a given location is called the intensity. It is measured on the Modified Mercalli Intensity (MMI) scale, which quantifies the level of shaking experienced by people and structures during an earthquake.
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 scale used to describe the amount of damage an earthquake causes is the Modified Mercalli Intensity (MMI) scale. This scale measures the intensity of shaking and the resulting damage at a specific location, rather than the earthquake's magnitude, which is measured on the Richter scale. The MMI scale ranges from I (not felt) to XII (total destruction), with each level representing a different degree of impact on structures and people.

The Modified Mercalli Intensity (MMI) level of the Japan earthquake on March 11, 2011, was around VII to IX, varying across different locations. The earthquake caused widespread damage and triggered a devastating tsunami that led to significant destruction and loss of life.

According to the US Geological survey the Haitian Earthquake had the capacity to cause some minor structural damage to buildings as far away as 300 km from the Earthquakes epicentre (level V or 5 on the Modified Mercalli Intensity scale. It was felt by humans as far away as Guantanamo in Cuba (level III or 3 on the Modified Mercalli Intensity scale) and would most likely have been detected by seismometers all over the world.

The amount of shaking produced by an earthquake at a given location is called the intensity. It is measured on the Modified Mercalli Intensity (MMI) scale, which quantifies the level of shaking experienced by people and structures during an earthquake.
The measure of how much damage an earthquake causes on the surface is determined by the earthquake magnitude and the distance from the epicenter. Earthquake damage can also be influenced by local geology and infrastructure resilience. The Modified Mercalli Intensity (MMI) scale is commonly used to assess the level of shaking and resulting damage.
it was recorded to be a 9.2 magnitude earthquake so it was very powerful. magnitude is what they measure for the Richter scale
