magnitude scale
Seismic intensity ranking
A magnitude scale measures the size or intensity of phenomena, typically earthquakes or celestial brightness.
The Richter scale measures earthquake magnitude logarithmically—each whole number represents roughly ten times more ground motion.
Stellar magnitude works inversely: brighter stars have lower numbers.
The quake registered 6.2 on the magnitude scale.
