So with all these earthquakes in my hometown I was informed that the richter scale is no longer used (shows how much I know about geography!). So I was wondering what replaced it, and how its different.
If you wikipedia the moment magnitude scale, it gives you all the information you need, and explains it way better than I possibly could. :)
The Magnitude scale replaced the Richter scale, but in most cases they still use the richter scale as well.
Oh wow, its been used since before I was born. Seriously, why do I even know about the richter scale?
That's what I thought when I read about it haha :)
