Introduction
A powerful earthquake rocked central Peru on Saturday, leaving a trail of destruction and loss. The 5.1-magnitude tremor, followed by a 3.7 aftershock, has claimed at least six lives and injured more than 30 people, according to authorities.
Details of the Quake
The U.S. Geological Survey (USGS) reported the main quake struck at 9:24 p.m. local time on July 18, 2026. Its epicenter was located 1.24 miles west-southwest of Sicaya, in the Huancayo province of the Junín region, at a depth of 6 miles. The epicenter was approximately 300 km (186 miles) east of Lima. The European-Mediterranean Seismological Centre initially estimated a magnitude of 5.6. The Geophysics Institute of Peru reported the epicenter's depth as 24 km (15 miles).
Seventeen minutes later, a 3.7-magnitude aftershock hit the same area. Peru's National Seismological Center confirmed the quakes, noting the first was 24 km deep and the second 18 km.
Casualties and Damage
Luis Vásquez, head of Peru's National Civil Defense Institute, initially confirmed five deaths, but later the death toll rose to six. The prime minister, Luis Enrique Arroyo, reported six dead and 32 injured, with only six still hospitalized. At least 21 people were injured, and around 300 were displaced. The hardest-hit area is Chongos Bajo, in the Chupaca province, where many adobe homes collapsed. Officials report 48 homes destroyed and more than 250 affected, leaving families in tents. Preliminary reports also indicated 18 homes had been damaged, in addition to the 48 destroyed. Rescue crews are searching for possible trapped victims.
In the regional capital Huancayo, two hospitals were damaged: the Daniel Alcides Carrión Hospital and the El Carmen Mother and Child Hospital, which saw cracks in its pediatric ICU. Historic landmarks, including the Cani Cruz stone cross and the Santiago de León convent, also suffered damage. Power outages affected several districts, but major roads remained intact.
The type of construction in the Andean zone, with rustic adobe material or a wood, cane and mud blend called “quincha”, contributed to greater impact and damage, Vásquez said. Rescue workers are continuing search and rescue operations, and health brigades have been deployed. The governor of Junín, Zósimo Cárdenas, identified victims including an 18-year-old and four adults aged 69 to 73. The age of the sixth victim was not released. In the town of Huayucachi, Mayor Miller Vásquez said at least 50 homes were uninhabitable, and aid such as blankets, tents, and food has been distributed.
President-elect Keiko Fujimori expressed her condolences on social media, saying, “I deeply regret the consequences of the earthquake that occurred in Junin. I express my most heartfelt condolences to the families of those who have passed away and my solidarity with those who have been affected.”
Images broadcast by local media captured the anguish of victims’ relatives in one of the hardest-hit areas, the agricultural region of Chongo Bajo, where residents huddled under blankets outside severely damaged homes. Animals were also seen under the rubble. “My home has been destroyed,” Hermenegilda Guamalato told a local radio station as she sought a place to stay with her three children in the neighbouring district of Huayucachi. An unnamed resident of Chongos Bajo told the N television network, “The earthquake destroyed our home. Here there are many adobe houses that collapsed.”
According to the USGS PAGER, 459,000 people are estimated to have felt very strong shaking, 155,000 strong, 86,000 moderate, and 324,000 light. The USGS issued a Yellow alert for shaking-related fatalities and economic losses. Overall, the population in this region resides in structures that are highly vulnerable to earthquake shaking, though some resistant structures exist. The predominant vulnerable building types are mud wall and ductile reinforced concrete frame construction.
Officials also reported structural cracking at El Carmen Regional Maternal and Child Hospital, the National Hospital of Central Peru, and the Chupuro health center, although no reports indicated catastrophic structural failures.
Power outages affected several districts, including Sapallanga, Chilca, Chongos Bajo, Cullhuas, Acostambo, Pazos, and Huaribamba. Authorities said power has since been restored to most affected areas, although approximately 400 customers in Pumpunya remained without electricity as repair work continued on July 19.
Officials confirmed there was no reported damage to the National Road Network, the railway system, or most telecommunications infrastructure, allowing emergency crews to maintain access throughout the affected region.
The Ministry of Defense activated emergency response protocols immediately after the earthquake. More than 30 personnel from the Peruvian Army’s Rapid Disaster Response Company were deployed overnight to Chongos Bajo, where they have been supporting search and rescue operations, debris removal, security, and crowd management alongside local authorities.
The health response has included the establishment of three Advanced Medical Posts in the town of Pumpunya to treat affected residents, while the Daniel Alcides Carrión National Hospital continues caring for the injured.
USGS noted that earthquakes in this part of Peru have historically triggered secondary hazards such as landslides, although no significant landslide impacts were reported in the immediate aftermath of this event. Estimated economic losses are expected to remain below 1% of Peru’s GDP.
Peru’s National Civil Defense Institute said in a statement the total number of missing is still unknown. Several buildings collapsed or suffered structural damage, including the historic “Santiago de León” church and former convent in Chongos Bajo, which was built in 1565 and designated as national heritage site for being a 16th century “architectural gem.”
The epicenter was located 2 km (1 mile) ENE of Sicaya (population 6,842), 11 km (7 miles) WNW of Huancayo (population 456,250), 12 km (7 miles) WNW of Chilca (population 73,371), 14 km (9 miles) S of Concepción (population 11,330), and 37 km (23 miles) SE of Jauja (population 21,057), Junín, Peru.
According to Peru’s National Emergency Operations Center (COEN) and the National Institute of Civil Defense (INDECI), at least six people were killed, and 21 sustained injuries, while three homes were damaged.
The magnitude 3.7 aftershock prompted authorities to strengthen monitoring efforts and continue structural inspections across the region.
Reuters images showed the aftermath in Chupuro and Pumpunya, including destroyed homes and a damaged local church. In Chongos Bajo, debris from a local church was visible, and residents were seen praying next to the bodies of four victims.
Local California Context
While this event occurred in Peru, it serves as a stark reminder for California, which sits on the same Pacific Ring of Fire. Residents in seismic zones like Imperial County should review their earthquake preparedness plans, secure heavy furniture, and maintain emergency kits.
Background
Peru is highly seismically active due to its location on the Pacific Ring of Fire, which accounts for about 85% of global earthquakes. In 2007, a 7.9-magnitude quake near Pisco killed nearly 600 people. The Junín region experiences quakes of magnitude 5 or higher roughly every 13 years. Seismologists say Peru experiences at least 400 earthquakes per year, three quarters of which are so weak people do not feel them.
Conclusion
As rescue and assessment efforts continue, the full extent of the damage remains unclear. This tragedy underscores the importance of building resilience in earthquake-prone areas worldwide.
