An observation: the majority of the 3.0 + magnitude quakes have happened in the evening.
Fact: During the swarm last year, quakes were posted immediately with no delay. The policy change happened shortly afterward and quakes are never updated on weekends unless 2.5 +, and this is an automatic function which is not contolled by UofU. Don't have time myself, watching my six year old. Why doesn't some email and ask why the policy change?
Fact: this swarm has now had more earthquakes than last year's swarm, and Shirakawa will fill us in on when it surpasses it in cumulative energy.
Fact: this swarm is larger than the other "notable" swarms which YVO the has posted on historic quakes. It's bigger than 1995, 2004, and 2008/09. The only swarm that was bigger was 1985 and that was mostly outside the caldera.

Hello, the orbit of the moon is not circular, it's an ellipse. Same as the earth, who's orbit is not a perfect circle. Here's some stuff to explain it.
