What is the difference between earthquake strength and earthquake intensity?

An earthquake force can be defined as the force released during an earthquake, and the earthquake force expresses the epicenter and focus of the earthquake only, and it is measured on the Richter scale, which is a fixed degree that describes a specific event.

As for the intensity of the earthquake, it is the amount of human and material damage caused by the earthquake, which increases as we approach the epicenter. The disaster, and the Italian scientist "Marcalli" developed a 12-degree scale to classify the intensity of earthquakes, and other scientists made some improvements to it later.
