love your sequence concept. One deficiency: It started BEFORE 23:45 UTC 11 13 2013. Your next report should say it ended AFTER... 333 11 13 33 111 3

This is a very large EQ as a whole. Once again, many humans (not all) treated the ONE as separate times and spaces. Confusions, chaoses and one-sided measurements followed: 7.4? 6.8? 5.7? 5.4? Depth: 10KM? 24KM? 36KM? 48KM? BOhr-Eistein debate is an ONE-sided contest. The former put the latter to a shame by exposing the paradox: If you want to measure it, you have to stop it; Otherwise, you can't measure it. You can't eat your own shit. The shit has been going on for soooooooooooooooooo long.
