What do you know today that you didn't know yesterday?

I didn’t really need a lecture on seismology, but thanks all the same. 

Even taking into account the exponential nature of earthquake magnitudes, it still seems implausible. There are hundreds, perhaps thousands, of quakes every year. For a single quake to expend more energy than all those others, it would have to be a planet-buster.

I’m willing to retract my objection if you can provide a source.

if you had profited from the lecture then you should be able to look up the number of earthquakes of each magnitude that occurs in a decade, compute and add up the total relative energies of all but the largest one, and see for yourself if what i said was true.

So, no source, then. Okey dokey.
