Magnitude is the measure of the energy released by an earthquake. The Richter scale (M L), the first and most well-known magnitude scale, was developed by Charles F. Richter (1900-1985) at the California Institute of Technology. This was the magnitude scale used historically by early seismologists.

Most of these eruptions are very small in size. However, some of them are "effusive" rather than being "explosive." Effusive eruptions are characterized by lava flowing from the vent instead of ejecta being blasted from the vent.
