How is the strength of an earthquake measured
Measurement of the severity of an earthquake can be expressed in several ways, but the two most common scales used by seismologists are intensity and magnitude. Earthquake intensity. Intensity is a qualitative measure of the strength of shaking caused by an earthquake determined from the observed effects on people, objects and buildings. A correlation coefficient, often expressed as r, indicates a measure of the direction and strength of a relationship between two variables. When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables. Correlational studies are quite common in psychology, particularly because some ...Weegy: The strength of an earthquake can be measured by the Richter scale, [ while the aftereffects or damage from an earthquake is measured by the Mercalli scale. |Score 1| Janet17 |Points 50916| User: According to the Richter scale, a reading of 2.0 would cause damage, as opposed to a reading of 7.0, which would cause damage.

Each value of strength on the magnitude scale of an earthquake is ten ...
The earthquake moment magnitude scale measures the strength of an earthquake based on the energy of the quake. It is similar to the Richter scale in that it uses logarithmic math to calculate the severity. However, the Richter scale was replaced by the moment magnitude scale in the 1970s because the Richter scale tends to underestimate the ...It is the best single measure of overall earthquake size It does not saturate It can be estimated from geological observations It can be estimated from paleoseismology studies It can be tied to plate motions and recurrence relations Ground Motion Important Factors Source effects Magnitude or moment Rupture directivity Path effects Attenuation wi...Problem:The magnitude of an earthquake is measured relative to the strength of a "standa,Solvely solution: ["The magnitude of an earthquake is measured relative to the …Solution.
