Not to nit, but Richter is also not just log_10: a single point increase is ~32x more energy. This is due to the relationship between energy and shaking amplitude:
> The energy release of an earthquake,[27] which closely correlates to its destructive power, scales with the 3⁄2 power of the shaking amplitude[why?]. Thus, a difference in magnitude of 1.0 is equivalent to a factor of 31.6 in the energy released.[28] The elastic energy radiated is best derived from an integration of the radiated spectrum, but an estimate can be based on mb because most energy is carried by the high frequency waves.
- chrismorgan 5y ago¯\_(ツ)_/¯ Sounds like what they teach casually is simplified well past the point of accuracy and possibly even particular usefulness.
- zamfi 5y agoI mean, it’s still logarithmic. What’s a constant among friends?
- chrismorgan 5y agoAll my algorithms are O(1).
- foxes 5y agoDropping constant factor does not seem that important to be honest. The important thing to be exposed to/take away was the logarithmic behaviour. I'm sure if you want to go be a seismologist you will quickly learn all the details. If people realise the magnitudes are exponentially more damaging , then isn't that sufficient for the general audience?
