Seismic Monitoring Details
PHIVOLCS noted that while the earthquake was recorded by the Don Marcelino, Davao Occidental Seismic Station (station code DDMP), the number of available stations that recorded the earthquake was insufficient to locally determine all parameters at the time of the initial bulletin.
The agency initially reported the earthquake as magnitude 7.4 located 127 kilometers west-northwest of Ternate, Indonesia, but later refined the parameters in the tsunami bulletin to magnitude 7.6 in the Molucca Sea.
Official Monitoring
PHIVOLCS confirmed this will be the only tsunami information bulletin issued unless additional information becomes available. The agency emphasized that the public should always refer to the latest tsunami information posted at the official PHIVOLCS website.
