5.6 Earthquake 10 October 8:21 PM (GMT +13)

Tonga was hit by a 5.6-magnitude earthquake 15 minutes ago near Hihifo, Niues, the German Geosciences Center (GFZ) said.
The earthquake struck on Tuesday evening October 10, 2023 at 8:21 pm local time near Hihifo, Niueas, Tonga at a shallow depth of 10 km below the epicenter. Shallow earthquakes are felt closer to the surface than deep earthquakes. As seismologists review the data and refine calculations, or as other organizations release their reports, the exact magnitude, epicenter and depth of the quake could be revised over the next few hours or minutes.
Based on preliminary seismic data, the earthquake may not have caused significant damage, but a slight tremor in the epicenter area may have been felt by many.
Weak tremors may have been felt at Hihifo (pop. 820), located 96 km from the epicenter.
