Magnitude 5.0 Earthquake Strikes Near Tonga in South Pacific

Strong Quake Recorded Off Tonga Coast

A magnitude 5.0 earthquake struck the South Pacific Ocean near the island nation of Tonga on Monday, December 1, 2025. The seismic event occurred at approximately 3:54 pm local time (GMT +13), with its epicenter located 171 km (106 mi) from Tonga. The earthquake registered at a relatively shallow depth of 47 km (29 mi).

Seismic Details and Reporting Agency

The earthquake's coordinates were identified as 17.17°S latitude and 174.66°W longitude. The event was confirmed by the GFZ (German Research Centre for Geosciences), which reported the quake approximately five hours after its occurrence. The shallow depth of the earthquake means that seismic energy is released closer to the surface, which can sometimes lead to more pronounced shaking in nearby areas.

Minimal Impact and Felt Reports

Despite its magnitude, the earthquake was not widely felt by residents in the region, and no reports of damage have emerged. The closest larger town where some weak shaking might have been experienced was Hihifo, Tonga, located approximately 164 km (102 mi) northeast of the epicenter. Further afield, Pago Pago, American Samoa, situated 532 km (330 mi) from the epicenter, likely experienced only very weak shaking.

Regional Seismic Activity

The South Pacific Ocean, particularly around the Tonga region, is known for its high level of seismic activity due to its location on the Pacific Ring of Fire. Earthquakes are a frequent occurrence in this tectonically active zone. While this particular event caused no reported disruption, the region regularly experiences various magnitudes of seismic activity.
