How strong was this earthquake?
Light earthquakes are widely felt near the epicentre and can rattle windows, dishes and hanging objects. Damage is uncommon and usually limited to cracked plaster or fallen loose items.
A magnitude 4.3 earthquake radiates roughly 43 tons of TNT equivalent in seismic energy.
The USGS assigns this earthquake a significance score of 284, 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 06:21 local solar time at the epicentre, around dawn.
This event was deeper than 90% of the 104 earthquakes recorded in Guatemala in our catalogue and stronger than 28% of them.
Where was the epicentre?
The epicentre was located at 14.7891, -91.5250 — 4 km southwest of Almolonga. The closest other recorded event was a magnitude 5.0 earthquake 81 km southeast of here on 30 July 2026.
The nearest other settlements in our records are San Carlos Sija (20 km north-northwest), Momostenango (34 km north-northeast), Nuevo Progreso (45 km west) and Génova (46 km southwest).
Why the 129 km depth matters
At 129 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 is often felt across the surrounding area. 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 M4.3 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 129 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
2 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 4.3.
249 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 Puerto Madero on 17 July 2026. This M4.3 event released about 44,668 times less energy than that event.
18 earthquakes have been recorded within 100 km of this epicentre in the past year, 3 of them in the past 30 days.

Questions about this earthquake
How strong was the earthquake near Almolonga?
It measured magnitude 4.3 — a light earthquake. A magnitude 4.3 earthquake radiates roughly 43 tons of TNT equivalent in seismic energy.
How deep was the earthquake near Almolonga?
The focus was 129 km below the surface, which counts as intermediate.
Was the Almolonga earthquake felt at the surface?
At magnitude 4.3 and a focal depth of 129 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.
When did the earthquake near Almolonga happen?
25 August 2026 at 12:27 UTC.
Was there a tsunami?
No. The USGS record carries no tsunami-information link for this event.
Have there been aftershocks?
2 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 4.3.
How often do earthquakes happen near Almolonga?
249 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 Puerto Madero on 17 July 2026. This M4.3 event released about 44,668 times less energy than that event.
