5.1 Magnitude Peru Earthquake Kills Five and Injures More Than 20 Near Chupaca
A magnitude 5.1 Peru earthquake struck near Chupaca in Peru's Junín region on July 18, 2026, followed by a 3.7 aftershock, killing at least five people and injuring more than 20 others while damaging homes, hospitals and historic structures. [4] [5]
Overview of the Earthquake and Aftershock
The main quake hit at 21:24:34 local time with epicenter 7 km south of Chupaca at a depth of 24 km and intensity IV-V. [4] The aftershock occurred at 21:41:37 with epicenter 14 km southwest of Chupaca at 18 km depth and intensity III. [4] Peru's geophysical institute reported these exact parameters for the events that formed the core of the Peru earthquake sequence. [4] The main shock registered magnitude 5.1 at 21:24:34 local time with its epicenter 7 km south of Chupaca at 24 km depth and produced intensity IV-V. [4] Minutes later the 3.7 aftershock was recorded at 21:41:37 local time with its epicenter 14 km southwest of Chupaca at 18 km depth and intensity III. [4] These measurements come directly from the Instituto Geofísico del Perú and the Centro Sismológico Nacional. [4]
Casualties and Injuries
At least five people were killed and 21-26 others injured according to preliminary reports. [1] [5] Six injured remained hospitalized while 26 had been discharged. [5] Preliminary reports from authorities indicated at least five dead and 21 injured after the two earthquakes in Peru. [1] Other accounts confirmed five fatalities linked to the 5.1 magnitude event. [2] Updated preliminary tallies listed six deaths and more than 30 injured before later adjustments settled on at least five deaths with 21-26 injured. [5] Of those injured, 26 received medical attention and were discharged while six continued to receive hospital care. [5]

Damage to Infrastructure and Buildings
Damage was concentrated in Chongos Bajo where the first death occurred. [5] Affected structures include the Hospital Nacional del Centro Daniel Alcides Carrión, the Hospital Regional Materno Infantil El Carmen (with cracks in the pediatric ICU), the cross at Cani Cruz de Chongos Alto, and the Antiguo Convento de Santiago de León. [5] Power outages hit several districts but no national highway damage was reported. [5] The greatest concentration of damage occurred in the district of Chongos Bajo, the site of the first reported fatality. [5] The Hospital Nacional del Centro Daniel Alcides Carrión in Huancayo recorded damage to its facilities, and the Hospital Regional Materno Infantil El Carmen in the same city showed fissures in its pediatric intensive care unit. [5] The cross at Cani Cruz de Chongos Alto collapsed, and sections of the Antiguo Convento de Santiago de León suffered collapses. [5] Power service was interrupted in various districts of the affected zone. [5] Preliminary evaluations found no impacts on national road network highways. [5]
Response and Official Monitoring

Authorities from IGP and Indeci continue monitoring and urge residents to follow official information and maintain emergency plans. [4] The Instituto Nacional de Defensa Civil issued the latest damage reports while the viceminister of health provided updates on injuries. [5] The Comité de Operaciones de Emergencia Nacional confirmed the absence of national highway damage. [5] Officials from the Instituto Geofísico del Perú supplied the technical characteristics of the seismic events while competent authorities maintained ongoing monitoring. [4] Indeci and health officials stressed the need for residents to rely solely on information from official bodies such as the IGP and Indeci. [4]
Peru's Seismic Context
Peru's location in the Pacific Ring of Fire explains its frequent seismic activity. [4] The country forms part of the Cinturón de Fuego del Pacífico where 85 percent of the planet's seismic activity occurs due to the interaction of the Nazca and Sudamericana tectonic plates. [4] [5] This geological setting accounts for the repeated earthquakes recorded throughout Peru. [4]
Additional Context on the Peru Earthquake Sequence
The sequence of the Peru earthquake and its aftershock produced the reported effects across Junín without causing damage to the national highway system. [5] All figures on deaths and injuries remain preliminary according to the statements released by Indeci and health authorities. [5]
