Phivolcs allays fears of tsunami from Tonga quake
"No destructive Pacific-wide threat exists based on the historical and tsunami data. However, earthquakes of this size sometimes generate local tsunamis that can be destructive along coasts located within a hundred kilometers of the epicenter," said the Phivolcs.
Phivolcs added the quake occurred at 2:54 a.m. Philippine time, with a depth of 10 km and a preliminary magnitude of 6.5.
The United State Geological Survey, meanwhile, measured the quake at magnitude 6.4, at 2:53 a.m. It said the epicenter was:
- 152 km east-southeast of Neiafu, Tonga
- 345 km northeast of Nuku`alofa, Tonga
- 571 km south-southwest of Tafuna, American Samoa
- 578 km south-southwest of Pago Pago, American Samoa
- 596 km south of Apia, Samoa
USGS also said a magnitude-5.4 quake was recorded at 3:05 a.m. at 148 km east-southeast of Neiafu, Tonga, — DVM, GMA News
