How strong was this earthquake?

Strong earthquakes can cause significant damage in populated areas within roughly 100 km of the epicentre, particularly to older masonry buildings. Landslides and liquefaction become a real risk in susceptible ground.

A magnitude 6.7 earthquake radiates roughly 169,203 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 719, which meets 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 13:06 local solar time at the epicentre, around midday.

This event was deeper than 58% of the 274 earthquakes recorded in Peru in our catalogue and stronger than 100% of them.

Where was the epicentre?

The epicentre was located at -14.6414, -73.5236 — 31 km northwest of Aniso. The closest other recorded event was a magnitude 4.4 earthquake 36 km northeast of here on 15 December 2024.

The nearest other settlements in our records are Cotaruse (36 km northeast), Tambo (60 km southwest), Quilcata (67 km south) and San Pedro (70 km west-southwest).

Why the 99 km depth matters

At 99 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 produce strong, widely felt shaking. 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 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 4.4.

59 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.0 event near San Pedro on 17 May 2025. This M6.7 event released about 11 times more energy than that event.

4 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 Aniso?

It measured magnitude 6.7 — a strong earthquake. A magnitude 6.7 earthquake radiates roughly 169,203 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Aniso?

The focus was 99 km below the surface, which counts as intermediate.

Was the Aniso earthquake felt at the surface?

At magnitude 6.7 and a focal depth of 99 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Aniso happen?

20 August 2026 at 18:00 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 4.4.

How often do earthquakes happen near Aniso?

59 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.0 event near San Pedro on 17 May 2025. This M6.7 event released about 11 times more energy than that event.
