Question

Richter defined the magnitude of an earthquake to be M = log I/S , where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a “standard” earthquake, which is barely detectable. The magnitude of a standard earthquake is M = log S/S =

Answer 1

Answer:

0

Step-by-step explanation:

Answer 2

Richter Scale is used to measure the Intensity of Earthquake.

The Intensity of Earthquake lies between 2 to 10.

An Earthquake of intensity 7 is very harmful and intensity of 8 can destroy everything around that area.

An earthquake of intensity 8 is 100 times more powerful than earthquake of intensity 6, because it has base of 10 in it's Logarithm.

→→Magnitude of an earthquake to be $M = log_{10} I/S$ , where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a “standard” earthquake.

As, to find the magnitude of Standard earthquake,

Then , I=S

$M=log_{10}\frac{S}{S}\\\\M=log_{10}(1)\\\\ M=0, as log_{10}(1)=0$

So, M=0→→ Magnitude of a standard earthquake
