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 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.

level 67 you why i know this bec... i jus do it now
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. Please see the related question and link.
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).
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.
An intensity of VII on the Modified Mercalli Intensity scale can cause considerable damage to poorly built buildings. This level of intensity typically leads to partial collapse of structures with a likelihood of extensive damage.
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.
it was recorded to be a 9.2 magnitude earthquake so it was very powerful. magnitude is what they measure for the Richter scale
