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 4.2 earthquake radiates roughly 30 tons of TNT equivalent in seismic energy.
The USGS assigns this earthquake a significance score of 271, 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 18:51 local solar time at the epicentre, in the evening.
This event was deeper than 62% of the 271 earthquakes recorded in Peru in our catalogue and stronger than 15% of them.
Where was the epicentre?
The epicentre was located at -11.0466, -75.5000 — 17 km west-northwest of San Ramón. The closest other recorded event was a magnitude 4.5 earthquake 55 km southwest of here on 20 November 2025.
The nearest other settlements in our records are La Oroya (55 km southwest), Santa Rosa (65 km east-northeast), Pampa Hermosa (71 km east-southeast) and Satipo (85 km east-southeast).
Why the 106 km depth matters
At 106 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 M4.2 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 106 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.
29 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.6 event near Callao on 15 June 2025. This M4.2 event released about 126 times less energy than that event.
3 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 San Ramón?
It measured magnitude 4.2 — a light earthquake. A magnitude 4.2 earthquake radiates roughly 30 tons of TNT equivalent in seismic energy.
How deep was the earthquake near San Ramón?
The focus was 106 km below the surface, which counts as intermediate.
Was the San Ramón earthquake felt at the surface?
At magnitude 4.2 and a focal depth of 106 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.
When did the earthquake near San Ramón happen?
01 June 2026 at 23:53 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 San Ramón?
29 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.6 event near Callao on 15 June 2025. This M4.2 event released about 126 times less energy than that event.
