Are West, East valley faults connected?

The Philippine Institute of Volcanology and Seismology (Phivolcs) is studying whether there is a connection between the West Valley Fault and the East Valley Fault.

Ishmael Narag, officer-in-charge of the Seismological Observation and Earthquake Prediction Division of the Phivolcs, on Wednesday said the study is very important in order for them to determine if this would cause a longer rupture should the fault move.
