EQF, can't see what you are talking about. Your plot, which was posted here a couple of days after the quake, shows the tiniest of peaks at 88 E. At first glance most people would see the largest peak and say nothing was there are 88 E.

If they were to notice the tiny peak, they, and I, would think it insignificant. And, because none of us to my knowledge preserve your older plots, we can't vouch that there was any tiny peak posted here before this quake.
