Earthquake Update: Negros Island, Philippines

Based on the lower magnitude from Phivolcs, the max. MMI is V (moderate shaking), an enormous difference with the initial 6.4. The reason for the lower MMI is the lesser Magnitude and the greater distance to the coast.

UPDATE : There has never been a tsunami threat for other than the local Negros beaches.

UPDATE : As the earthquake occurred in the middle of the night when everybody was asleep, shaking damage and injuries cannot be excluded.
