Read More »The Richter scale is a scale of numbers used to tell the power (or magnitude) of earthquakes. Charles Richter developed the Richter Scale in 1935. His scale worked like a seismogram, measured by a particular type of seismometer at a distance of 100 kilometers (62 mi) from the earthquake. Earthquakes 4.5 or higher on the Richter scale can be measured all over the world. An earthquake a size that scores 3.0 is ten times the amplitude of one that scores 2.0. The energy that is released increases by a factor of about 32. Every increase of 1 on the Richter scale corresponds to an increase in amplitude by a factor of 10 so therefore, it is a logarithmic scale. Richter Scale Magnitude Descriptor Richter Magnitude number Damage caused by the earthquake Frequency of occurrence Micro Less than 2.0 Micro (very small) earthquakes, people cannot feel these. About 8,000 each day Very minor 2.0-2.9 People do not feel these, but seismographs are able to detect them. About 1,000 per day Minor 3.0-3.9 People often feel these, but they almost never cause damage. About 49,000 each year (About 134 per day) Light 4.0-4.9 Objects inside houses are disturbed, causing noise. Things are rarely damaged. About 6,200 each year (About 17 per day) Moderate 5.0-5.9 Buildings that are not built well may be damaged. Light objects inside a house may be moved. About 800 per year (About 2 per day) Strong 6.0-6.9 Moderately powerful. May cause a lot of damage in a larger area. About 120 per year Major 7.0-7.9 Can damage things seriously over larger areas. About 18 per year Great 8.0-9.9 Massive damage is caused. Heavy objects are thrown into the air and cracks appear on the ground, as well as visible shockwaves. Overhead highways may be destroyed, and buildings are toppled. About 1 per 20 years Meteoric 10.0+ There are no records of anything of this size. The vibration is about the same as that of a 24 km (15 mi) meteor. Unknown
