Peru endures aftershocks and landslides following July 18 quake

On July 18, 2026, a magnitude 5.4 earthquake struck the Junín province, destabilising Cerro Pucaá in Chupuro. The Instituto Geofísico del Perú (IGP) warned that the fractured slopes and low‑cohesion deposits could generate further rock falls and large dust clouds, especially when heavy rain arrives.

In the days that followed, the IGP recorded dozens of aftershocks across the country. Notable tremors included a magnitude 4.5 quake near Camaná (Arequipa) on July 22, a magnitude 4.0 event in Huaura (Lima) on July 24, and multiple magnitude 3‑4 quakes in Junín, Lima, Ica and other regions. No major damage or casualties have been reported.

Peruvian authorities advise residents to remain vigilant, avoid vulnerable slopes, and keep emergency kits ready as the rainy season approaches. The risk of landslides, debris flows and further dust clouds from Cerro Pucaá remains high while aftershocks continue.
