It could be the quake was caused by a volcanic eruption and not a usual plate shift and settling aftershock type of event ?

This link shows video of a plume emitting from the volcano and also cites there have been small tremors, and maybe these volcanic tremors are lower than what usgs reports on their maps for earth quakes?

Not sure but the volcano may be acting up as a result or cause of today's 7.1?

I don’t think so. Both times I was there for the Nascar events, it was venting both times then.
