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 5.8 earthquake radiates roughly 7,558 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 518, 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 23:00 local solar time at the epicentre, late at night.

This event was shallower than 60% of the 1,529 earthquakes recorded in Indonesia in our catalogue and stronger than 97% of them.

Where was the epicentre?

The epicentre was located at 1.2035, 126.3730 — 121 km west-northwest of Ternate. The closest other recorded event was a magnitude 5.3 earthquake 8 km south of here on 24 April 2026.

The nearest other settlements in our records are Bitung (120 km south-southwest), Jailolo (123 km east), Laikit, Laikit II (Dimembe) (161 km west-northwest) and Manado (195 km west-northwest).

Why the 35 km depth matters

At 35 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 M5.8 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

36 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 5.9.

302 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 7.8 event near Ternate on 01 April 2026. This M5.8 event released about 1,000 times less energy than that event.

84 earthquakes have been recorded within 100 km of this epicentre in the past year, 35 of them in the past 30 days.
