We are just a few days after the new moon. Actually the original quake was even closer to the new moon. While the full moon can also cause tidal stress, the new moon is even stronger because both the moon and the sun are pulling on the same side with gravitation. As the earthquake was not enought, volcano Popocatepetl erupted the same day killing 15, as you can see at the other link below.

I decided to take another look at the phases of the moon link. The big 8.1 magnitude quake happened on Sept. 8 with was 2 days after the full moon.
