This is the reason why Phivolcs got the location of the epicenter wrong, it was USGS who corrected them.
And the earthquake epicenter is a "new" deep(buried) fault line.

In my personal opinion, numerous small earthquakes will "rarely" leads to a big one, In my opinion also, if the Big One happens it will not be along the west valley fault it could be parallel to it or across it. For your peace of mind check your area hazard map and look if there are other small faults passing your place thats connected to the west valley fault. Then check what kind of soil your house is built on, there are soil types that can withstand a strong earthquake.
Both of them neither got it right nor wrong. Phivolcs already got the plot/location right but could not decide if it was correct because the fault that was historically known to cause a large earthquake and tsunami in the 90s was farther away. Thats why it was called a blind fault, no earthquake has occurred in the area since the 1900s when observational seismology was applied in the Philippines by the Jesuits and Americans.
