It was recorded to be magnitude 9.5 on the Richter scale and if you wanted to know it was considered 'CATASTROPHIC' (XII) on the Mercalli scale which measures the intensity of the earthquake

There is no absolute top to the Richter scale, although the largest earthquake ever recorded by mankind was the Valdivia earthquake in Chile that was the equivalent of 9.5 on the Richter scale in 1960. While no earthquake any stronger has ever been recorded, the impact that caused the Chicxulub crater in the Yucatan Peninsula about 65 million years ago has been calculated to have been the equivalent of about 13.0 on the Richter scale.
