Yeah you are right, this P-wave may be a red herring.
I had a look back on the last 3 Very Strong Global quakes and the sequence doesn't follow correctly.
I forgot about the Marianas quake on 13/8 after the Ecuador one and before the Darfield.
If the P-wave theory was to be followed and using the 103 line as a reference it should have gone like this
Vanuatu quake of 10/8
The p-wave 103 runs through such places as Chile, Costa Rica, Texas, Kashmir/Pakistan, South Sandwich Islands
but the next Very Strong quake was in Ecuador (admittedly within the shadow 103-140)
Ecudaor quake of 12/8
The P-wave 103 runs through New Zealand, Ballaney Islands, South Africa, Congo, Greece, end of the Aluetians , Samoa, Tonga
but the next Very Strong quake was in Marianas Island
(admittedly just within the shadow 103-140)
Marianas quake of 13/8
The p-wave 103 runs through Mexico, Greenland, Iceland, Greece, African Rift Valley, Madagascar
but the next Very Strong quake was in New Zealand
and thats where it all falls apart, the 103 line or for that matter the 103-140 shadow of the Marianas quake doesn't come anywhere near New Zealand
The only way it would work is if you discount the Marianas which USGS downgraded to 6.9. Maybe 7.0Mw is the treshold
still, 2 out of 3 subsequent quakes DID occur within the shadow line, thats enough to make me want to investigate further.
I'll waste a day on it, its blowing 100+kmph here right now, got the day off.
