A powerful earthquake peru today shook southern Peru on Thursday, August 20, sending strong tremors through Ayacucho and other parts of the country. The earthquake was felt hundreds of kilometres away, including in Lima, as authorities began assessing damage and checking for injuries.
The US Geological Survey (USGS) recorded the earthquake at magnitude 6.7, while Peru’s Geophysical Institute (IGP) reported a magnitude of 7.2. The difference comes from the agencies using different seismic calculations and reporting systems.
The earthquake has quickly become a major search topic, with people looking for updates on the Peru earthquake today, its epicenter, magnitude, damage, casualties, aftershocks and possible tsunami threat.
What happened in Peru today?
The earthquake struck at around 1:00 p.m. local time on August 20, 2026, in the southern part of Peru.
According to the IGP, the epicenter was approximately 35 kilometres north of Coracora, in the Parinacochas province of the Ayacucho region. The institute reported a depth of around 108 kilometres.
USGS gave a different estimate, reporting a magnitude of 6.7 and placing the earthquake at a depth of approximately 66.7 kilometres.
Despite the differences in measurements, both agencies confirmed that a strong earthquake struck the southern Andes region.
Peru earthquake magnitude: Was it 6.7 or 7.2?
One of the biggest questions surrounding the event is why different numbers are being reported.
The USGS reported magnitude 6.7, while Peru’s IGP initially reported 7.2. This does not necessarily mean that one agency is wrong. Earthquake magnitude can be calculated using different methods, seismic stations and data processing models.
For international reporting, the USGS figure of 6.7 is frequently being used. However, because the IGP is Peru’s national geophysical authority, its 7.2 measurement is also important when discussing the event locally.
For readers searching for “6.7 earthquake Peru” or “7.2 earthquake Peru,” both terms therefore refer to the same major earthquake.
Where did the earthquake hit in Peru?
The earthquake occurred in the Ayacucho region of southern Peru, with the epicenter near Coracora.
Strong shaking was reported in several communities around the epicentral area. The tremor was also felt in other parts of southern and central Peru, including areas of Ica, Arequipa, Huancavelica, Apurimac and Cusco. Reports also said the shaking was felt in Lima.
The wide area in which the earthquake was felt explains why searches for “earthquake in Peru today” and “Ayacucho earthquake today” increased rapidly.
Earthquake damage and injuries
Initial reports changed as authorities continued inspecting buildings and infrastructure.
The latest reports indicated that several people were injured during the earthquake and evacuation, while homes and public infrastructure were affected in parts of Ayacucho and nearby areas. AP reported at least two injuries and damage involving homes, health centres and a school.
A later update from Peruvian authorities reported damage to a number of public buildings and educational facilities, showing that the impact assessment was still developing on August 21.
This is why early earthquake reports can look different from later updates: authorities need time to inspect buildings, roads, schools and health facilities before confirming the full extent of damage.
Was there a tsunami warning after the Peru earthquake?
There was no tsunami threat reported from this earthquake.
The Peruvian Navy confirmed that the inland earthquake did not pose a tsunami threat, while tsunami monitoring agencies also reported no tsunami danger associated with the event.
This is particularly important because many people searching for “Peru earthquake tsunami warning” may be concerned after seeing reports of a strong earthquake.
A strong earthquake does not automatically mean a tsunami will occur. The earthquake’s location, depth and movement of the seafloor are among the factors that determine tsunami risk.
Was the earthquake felt in Lima?
Yes. The earthquake was felt in Lima, although the strongest shaking was reported closer to the epicentral region in southern Peru.
The distance between the epicenter and Lima meant that the capital experienced weaker shaking compared with communities closer to Ayacucho. Reports also indicated that the tremor was felt across several other regions.
For people searching “Peru earthquake today Lima”, the key point is that the earthquake was generated in southern Peru but its shaking travelled across a much wider area.
Why was the earthquake so widely felt?
Peru sits along the Pacific Ring of Fire, one of the world’s most seismically active regions.
The country’s location is strongly influenced by the interaction between the Nazca Plate and the South American Plate. The Nazca Plate is being pushed beneath the South American Plate, a process known as subduction.
That geological setting makes earthquakes a recurring natural hazard in Peru.
The depth of a particular earthquake can also influence how much damage occurs at the surface. In this case, the event was relatively deep, which helped limit some of the destructive effects despite its high reported magnitude.
Are there aftershocks in Peru?
After a major earthquake, smaller earthquakes known as aftershocks can occur.
Reports on August 21 indicated that additional seismic activity had been recorded following the main event, including tremors reported by Peru’s seismic monitoring authorities.
Aftershocks can sometimes be felt strongly, particularly near the epicentral area. Residents in affected regions are therefore advised to follow instructions from local authorities and avoid entering buildings that may have been structurally damaged.
What should people do after an earthquake?
People in affected areas should remain alert even after the main shaking has stopped.
If a building has visible cracks, structural damage or other signs of instability, people should avoid entering until it has been inspected. Residents should also keep emergency supplies accessible and follow official instructions.
During an aftershock, the basic safety principle remains: Drop, Cover and Hold On.
People should also be cautious around damaged roads, fallen rocks, power lines and unstable structures.
Peru earthquake today: Latest situation
The earthquake that struck southern Peru on August 20 remains under assessment as authorities inspect affected communities and infrastructure.
The most important confirmed details are:
- Location: Ayacucho region, southern Peru
- Date: August 20, 2026
- Time: Around 1:00 p.m. local time
- USGS magnitude: 6.7
- IGP magnitude: 7.2
- Epicenter: Around 35 km north of Coracora, according to IGP
- Depth: IGP reported 108 km; USGS reported about 66.7 km
- Areas affected: Ayacucho and other parts of southern and central Peru
- Lima: Tremors were felt
- Tsunami threat: No tsunami threat reported
- Damage: Homes and public infrastructure affected in some areas
- Injuries: Injuries reported during the event and evacuation
These figures can change as seismic agencies and emergency authorities update their assessments.
Final word
The Peru earthquake today is a reminder of the country’s exposure to powerful seismic events. While the USGS measured the earthquake at 6.7 and Peru’s IGP reported 7.2, both measurements describe the same significant event in the Ayacucho region.
The good news is that there was no tsunami threat, while authorities continue assessing damage and monitoring for aftershocks. For people in affected areas, following official emergency guidance and staying away from damaged structures remain the most important precautions.
As more information becomes available, details about injuries, infrastructure damage and aftershocks may be updated.
