How strong was this earthquake?

Moderate earthquakes can damage poorly built or unreinforced structures near the epicentre, while well-engineered buildings typically escape serious harm. Shaking is often strong enough to wake sleeping residents over a wide area.

A magnitude 5.0 earthquake radiates roughly 477 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 385, which is below the USGS threshold of more than 600 for its significant-earthquake list. The ranking combines magnitude with available Did You Feel It responses and PAGER alert level; it is not a direct measurement of damage.

When it happened locally

That is about 16:30 local solar time at the epicentre, during the afternoon.

This event was deeper than 81% of the 416 earthquakes recorded in Tonga in our catalogue and stronger than 69% of them.

Where was the epicentre?

The epicentre was located at -16.2600, -175.4220 — 177 km west of Hihifo. The closest other recorded event was a magnitude 4.3 earthquake 44 km southwest of here on 29 August 2026.

The nearest other settlements in our records are Mata-Utu (139 km northwest), Alo (218 km west-southwest) and Neiafu (223 km south).

Why the 324 km depth matters

At 324 km this was a deep-focus earthquake, occurring well inside the subducting slab rather than in the crust. Deep events are rarely damaging even at large magnitudes, though they can be felt over very long distances.

This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size can be felt widely and may cause minor local damage. Its deep focus normally weakens surface shaking while spreading perceptible motion over a broad area.

What does the tsunami information flag mean?

The USGS record does not carry a link to NOAA tsunami information. That field is not an all-clear and does not state whether a tsunami occurred. In this case, a damaging tsunami would be less likely because at M5.0 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 324 km focal depth is too great to deform the sea floor significantly; it occurred inland rather than beneath the sea floor. For an active coastal alert, use tsunami.gov or your local warning authority.

Aftershocks and local seismic history

No further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event.

131 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.6 event near Mata-Utu on 24 July 2025. This M5.0 event released about 251 times less energy than that event.

No other earthquakes have been recorded within 100 km of this epicentre in the past year, which makes this a genuinely isolated event.

Questions about this earthquake

How strong was the earthquake near Hihifo?

It measured magnitude 5.0 — a moderate earthquake. A magnitude 5.0 earthquake radiates roughly 477 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Hihifo?

The focus was 324 km below the surface, which counts as deep.

Was the Hihifo earthquake felt at the surface?

At magnitude 5.0 and a focal depth of 324 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Hihifo happen?

14 January 2025 at 04:12 UTC.

Was there a tsunami?

No. The USGS record carries no tsunami-information link for this event.

Have there been aftershocks?

No further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event.

How often do earthquakes happen near Hihifo?

131 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.6 event near Mata-Utu on 24 July 2025. This M5.0 event released about 251 times less energy than that event.
