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 05:56 local solar time at the epicentre, around dawn.

This event was shallower than 99% of the 734 earthquakes recorded in the Philippines in our catalogue and stronger than 69% of them.

Where was the epicentre?

The epicentre was located at 7.0559, 127.0650 — 60 km east-southeast of Santiago. The closest other recorded event was a magnitude 5.5 earthquake 26 km north of here on 07 January 2026.

The nearest other settlements in our records are San Ignacio (28 km south), Manay (28 km south-southeast), Jovellar (30 km south-southwest) and Baculin (33 km north-northeast).

Why the 10 km depth matters

At 10 km this was a shallow earthquake. Shallow events release their energy close to the surface, so for a given magnitude they produce noticeably stronger shaking — and more damage — than deeper ones. Roughly three quarters of all earthquakes worldwide occur at shallow depths.

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 shallow focus makes stronger surface shaking more likely than for a deeper event of the same magnitude.

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; 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

1 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 4.9.

314 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 7.4 event near Santiago on 10 October 2025. This M5.0 event released about 3,981 times less energy than that event.

78 earthquakes have been recorded within 100 km of this epicentre in the past year, 58 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Santiago?

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 Santiago?

The focus was 10 km below the surface, which counts as shallow.

Was the Santiago earthquake felt at the surface?

At magnitude 5.0 and a focal depth of 10 km, shaking would have been concentrated near the epicentre.

When did the earthquake near Santiago happen?

31 October 2025 at 21:27 UTC.

Was there a tsunami?

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

Have there been aftershocks?

1 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 4.9.

How often do earthquakes happen near Santiago?

314 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 7.4 event near Santiago on 10 October 2025. This M5.0 event released about 3,981 times less energy than that event.
