What is the magnitude scale of an earthquake?
Earthquakes with the magnitude of 2.5 or less are never felt but can be recorded on the richter scale and there are about 900,000 of these earthquakes each year.
Then there is earthquakes from 2.6 to 5.4 which are rarely felt and if felt causes little damage.For example just drops a doll of the bed.These kinds of earthquakes occur only about 30,000 each year.
Earthquakes from 5.5 to 6.0 causes some damage but mostly only to buildings that are weakly structured such as mobile homes and cabins in the woods.but these kinds if earth quakes happen only about 500 times a year.
Earthquakes from 6.1 to 6.9 cause lots of damage even if your 100 kilometers away,and are estimated to occur 100 times each year.
Earthquakes with the magnitude of 7.0 and higher are major earthquakes that can cause serious damage to any kind of buildings.These on other hand happen only about 20 times or even less.
