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 5.5 earthquake radiates roughly 2,682 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 471, 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 00:06 local solar time at the epicentre, in the early hours of the morning.

This event was deeper than 69% of the 65 earthquakes recorded in Ecuador in our catalogue and stronger than 94% of them.

Where was the epicentre?

The epicentre was located at -4.0154, -77.8346 — 104 km east of Yantzaza. The closest other recorded event was a magnitude 5.3 earthquake 40 km east-northeast of here on 10 September 2026.

The nearest other settlements in our records are Gualaquiza (59 km north-northeast), Sucúa (157 km north-northeast), Alianza Cristiana (167 km east) and Barranca (169 km east-southeast).

Why the 108 km depth matters

At 108 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 M5.5 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 108 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.

26 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.5 event near Piñas on 22 October 2025. This M5.5 event released a comparable amount of energy to that event.

1 earthquakes have been recorded within 100 km of this epicentre in the past year, 0 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Yantzaza?

It measured magnitude 5.5 — a moderate earthquake. A magnitude 5.5 earthquake radiates roughly 2,682 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Yantzaza?

The focus was 108 km below the surface, which counts as intermediate.

Was the Yantzaza earthquake felt at the surface?

At magnitude 5.5 and a focal depth of 108 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Yantzaza happen?

08 January 2026 at 05:17 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 Yantzaza?

26 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.5 event near Piñas on 22 October 2025. This M5.5 event released a comparable amount of energy to that event.
