in the ricter scale how much more is point one and stuff?

Question

ok like how much more force is in a 3.3 quake than 3.4 like is it X5, X10, +2? tell me plz i cant find out.

Answer 1

Both the magnitude and the seismic moment are related to the amount of energy that is radiated by an earthquake. Richter, working with Dr. Beno Gutenberg, early on developed a relationship between magnitude and energy. Their relationship is:

logES = 11.8 + 1.5M

giving the energy ES in ergs from the magnitude M. Note that ES is not the total ``intrinsic'' energy of the earthquake, transferred from sources such as gravitational energy or to sinks such as heat energy. It is only the amount radiated from the earthquake as seismic waves, which ought to be a small fraction of the total energy transfered during the earthquake process.

More recently, Dr. Hiroo Kanamori came up with a relationship between seismic moment and seismic wave energy. It gives:

Energy = (Moment)/20,000

For this moment is in units of dyne-cm, and energy is in units of ergs. dyne-cm and ergs are unit equivalents, but have different physical meaning.

Answer 2

It is a base-10 logarithmic scale obtained by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a seismometer output. Measurements have no limits and can be either positive or negative.

So much for the math. The below scale is much more descriptive:

Microearthquakes: 2.0 Not felt. About 8,000 per day

Very minor 2.0-2.9 Generally not felt, but recorded. About 1,000 per day

Minor 3.0-3.9 Often felt, but rarely causes damage. 49,000 per year (est.)

Light 4.0-4.9 Noticeable shaking of indoor items, rattling noises. Significant damage unlikely. 6,200 per year (est.)

Moderate 5.0-5.9 Can cause major damage to poorly constructed buildings over small regions. At most slight damage to well-designed buildings. 800 per year

Strong 6.0-6.9 Can be destructive in areas up to about 100 miles across in populated areas. 120 per year

Major 7.0-7.9 Can cause serious damage over larger areas. 18 per year

Great 8.0-8.9 Can cause serious damage in areas several hundred miles across. 1 per year

Rarely, great 9.0 or greater Devastating in areas several thousand miles across. 1 per 20 years

Answer 3

It's a logarithmic scale. For each increase of 2 on the Richter scale there's a 1000 fold increase in power of the earthquake.

An increase of 1 means a 32 fold increase in power (the square root of 1000) and an increase of 0.1 would be about double.

Answer 4

It's a 10 based log scale,, ie: the number is the exponent applied to 10. simply apply it and you can see what the increase is.

Answer 5

its about as much as a really nasty fart
