The Richter scale measures the strength of earthquakes. Bulgaria is a country, not an earthquake.
The Haiti earthquake measured around 7.0 on the Richter Scale.
No. The Richter scale is a way for scientists to describe how much energy was released by an earthquake (this is known as the earthquakes magnitude).
The Richter Scale best describes how much energy an earthquake releases also known as it's magnitude.
earthquake magnitude is exponential, not linear. for every increase of 1 on the Richter scale, an earthquake releases 10 times as much energy. The Richter scale has been superseded the moment magnitude scale (MMS). MMS is still logarithmic, but deviates somewhat from the Richter scale (an increase of one indicates about 30 times as much energy). Certain equations or algorithms might be designed for a linear scale, but for most applications a linear scale would be unnecessary and impractical. == == == ==
the mercalli scale uses roman numerals and measures how much damage there was in the earthquake. the richter scale uses a needle with ink and does sort of a line graph and measures the magnitude of an earthquake.
The Richter scale measures how much energy is released by an earthquake.
The change in magnitude is (6.2 - 4.2) 2.0. This is equivalent to a 100 times increase in seismic wave amplitude (as each increase of 1 on the scale is a 10 times increase in amplitude therefore 10 * 10 = 100)..
Concerning that the highest reading is 7, so a 6.3 Richter can cause very big damage
An earthquake measuring 5.4 on the Richter scale would have 10 times higher wave amplitude compared to one measuring 4.4. The Richter scale is logarithmic, so each whole number increase corresponds to a 10-fold increase in amplitude.
The Richter scale determines earthquake magnitude by measuring how much the ground moves, and the Modified Mercalli Intensity Scale determines earthquake intensity based on damage to buildings and effects on humans.
This is really an answer but we dont use the ricter scale to record earthquakes because it didn't work well.. we use the M.M.S (Moment Magnitude Scale) To record earthquakes.. ----
