log an earthquake?

Question

earthquake 1 measures 6.2 on a richter scale and earthquake 2 measures 8.2 since this is a logaritmic function how much bigger is earthquake 2 than earthquake1?

Answer 1

a 7.2 is 32x bigger than the 6.2 and an 8.2 is 32x bigger than the 7.2. an 8.2 is 1024x stronger than a 6.2. scientist used to think that there was a 10x difference. this is not the case. a 6.2 will knock down small buildings , but an 8.2 will destroy entire cities.

Answer 2

Dear friend. Mr Charless Richter found only a method to measure the earthquake magnitude for the local areas in California from Pasadena university in the year 1935. He used the Wood Anderson seismometer to calculate the energy released. The shaking for each Richter scale will increase by ten times for each Richter scale. But the energy release is about 32 times more for each Richter scale. Therefore 6.2 to 8.2 is 1024 times stronger. Generally people mistake it as ten times bigger for each Richter scale. I am giving below the chart for energy release related to Richter scale. Approximate TNT Yield for Seismic Energy

1 30 lbs
2. 1 ton
3. 29 ton
4. 1000 ton
5. 32000 ton
6. 1 million ton
7. 32 million ton
8. 1 billion ton
9. 32 billion ton
10 1 trillion ton.

Answer 3

100 times. Scale of 10. a 7.2 is 10 times bigger than a 6.2. An 8.2 is 10 times bigger than 7.2. 10 x 10 = 100.
