An earthquake measuring 7 on the Richter scale releases about how many times more energy than an earthquake with a magnitude of 6?

Given that the Richter scale is a base 10- logarithmic measure of the amplitude of an earthquake, determine how much stronger an earthquake that measures 6.9 is than one that measures 5.4.
How do you do this?? Explanation and answer please 🙂

If the LA earthquake had a magnitude of 6.5 on the Richter scale and the magnitude of the San Francisco earthquake had a magnitude 35 times as intense as the LA earthquake, what is the magnitude of the San Francisco earthquake?

What is the measure of an earthquake that is 10 times as intense as an earthquake measuring 5.2 on the richter scale
i think you need to use log

how many orders of magnitude greater is an earthquake rated at 4 on the Richter scale than an earthquake rated at 3 and at 2

We’ve been told that there are a number of flaws to the Richter scale (ML), the limitations of the original instrumentation, that it was only designed for use in California and that shallow earthquakes are a practical problem. Can you explain why this should be?
Reading it back, maybe the point is it only works for shallow earthquakes?!

I’m doing a project in algebra on earthquakes. I think that it might be the Richter scale and the mercalli scale. but there’s also a seismograph…so im not sure which two to use.

why or why not?

and can the it also be high on the mercalli scale but low on the richter scale?

An earthquake with a reading of 7.0 on the Richter scale releases ten times as much energy as an earthquake that registers 6.0 on the scale. If x represents the amount of energy released by a 6.0 earthquake, write an expression for the amount of energy released by a 7.0 earthquake.

First it was the earthquake in Haiti. Then it was the earthquake in Chile. 2 major earthquakes within a month of each other. Now there’s been some tremors in california, one even going as high as 4.3 on the richter scale. And im wondering… Are these earthquakes leading up to something big? Such as The Big One?
