The Richter scale is used to measure the magnitude of earthquakes. The scale readings are such that 1 represents an earthquake that is observed only on instruments, while 3 Indicates a quake felt only by people near its epicenter. A reading of 7 represents a major quake, usually accompanied by substantial destruction. A sample of 16 earthquakes occurring in the United States had reading on the Richter scale of:

1.0 , 2.2 , 1.4 , 5.1 , 3.3 , 2.2 , 1.3 , 1.5 , 2.0 , 3.1 , 4.6 , 1.2 , 1.8 , 2.9 , 3.5 , 6.2
