 Yes

It depends on how you look at it.

There are two types of miss in Earthquake Prediction .

1) Date predicted and there is no 6+ quake in window period 

2) Date in not predicted and a 6+ quake occurs.

PNG Quake comes under second category 

  I leave it to you to decide

Nevertheless look at epicenter location hypothesis. 

Moon is setting ( sharp) at epicenter
