It appears that the current episode of EQs off the northern tip of Vancouver Island is trailing off.

I don't know how this relates to lunar cycles but it certainly seems that earth flexing is occurring in that area and generating the EQs. The episode appears to be settling down again.

The techtonics of the Pacific Northwest is unique so these types of events are to be expected. The plates are on the move in a highly complex collision with a high amount of torque, twisting and subduction.

But what is the straw that breaks the camel's back to make an EQ or series of EQs happen at a particular time? Obviously, tensions are building on faults all the time but what small precipitating events act as a triggering mechanism?

That is where lunar, solar, and/or gravitational tidal effects play a roll and that is where tracking EQs against the background of these possible triggering effects will prove to be valuable.

This swarm in still intriguing.
We are now out of the perigee week, as of 29 15:45, but we have been in the week of the lunar Mid Point since 28 19:11.  Today the Moon crossed the Equator going south, and today is the New Moon.

The lunar apogee is Sept  07  at 14:59  

Both the Mid Point and the Maximum Velocity dates are on September 1, so I would expect only one 6M quake in their weeks.  A quake already occurred:

  6.3M   2008/08/30 06:54:06    -6.194    147.256  56.0   EASTERN NEW GUINEA REG, PAPUA NEW GUINEA

This could well be related to the Moon crossing the Equator, so we may well get another one.

The EQ total for Vancouver Island since the current episode began is now up to 34 of Mag 3.8 or higher. At the time of this writing there had been another EQ within the last hour.

The largest EQ of 5.9 on the 28th of August is still the largest of the series, but it does appear the current activity is subsiding.
