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 5.3 earthquake radiates roughly 1,344 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 432, 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 05:41 local solar time at the epicentre, around dawn.

This event was deeper than 78% of the 1,608 earthquakes recorded in Indonesia in our catalogue and stronger than 91% of them.

Where was the epicentre?

The epicentre was located at 0.5266, 121.6990 — 151 km west of Gorontalo. The closest other recorded event was a magnitude 4.5 earthquake 12 km south of here on 17 February 2026.

The nearest other settlements in our records are Gorontalo (156 km east-southeast), Luwuk (182 km south-southeast), Poso (222 km south-southwest) and Palu (255 km southwest).

Why the 104 km depth matters

At 104 km this was an intermediate-depth earthquake. Energy from events at this depth spreads out before it reaches the surface, which usually means weaker shaking near the epicentre than a shallow quake of the same magnitude, but shaking felt across a wider area.

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 intermediate depth normally reduces peak shaking near the epicentre compared with a shallow 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 M5.3 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 104 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 since this event was recorded.

100 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.7 event near Palu on 16 June 2026. This M5.3 event released about 126 times less energy than that event.

18 earthquakes have been recorded within 100 km of this epicentre in the past year, 1 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Gorontalo?

It measured magnitude 5.3 — a moderate earthquake. A magnitude 5.3 earthquake radiates roughly 1,344 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Gorontalo?

The focus was 104 km below the surface, which counts as intermediate.

Was the Gorontalo earthquake felt at the surface?

At magnitude 5.3 and a focal depth of 104 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Gorontalo happen?

11 October 2026 at 21:34 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 since this event was recorded.

How often do earthquakes happen near Gorontalo?

100 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.7 event near Palu on 16 June 2026. This M5.3 event released about 126 times less energy than that event.
