Two earthquakes struck the Junín region of Peru on Saturday night, killing at least six people and injuring 21 [1, 2].
The disaster highlights the vulnerability of mountainous communities in central Peru, where seismic activity can lead to rapid structural collapse and significant casualties in remote provinces.
The tremors hit the Chupaca province, located in the Andes mountains approximately 300 km east of Lima [1, 2, 3]. Peru's civil defence chief said the casualties followed the twin seismic events [1, 2].
According to Peru's National Seismological Centre, the first quake registered a magnitude of 5.1 at a depth of 24 km [1, 3]. A second quake followed with a magnitude of 3.7 at a depth of 18 km [1, 3]. While some reports cited a single magnitude of 5.6 [3] or 5.5 [2], the National Seismological Centre provided the specific dual-magnitude data.
The impact on the local population was extensive. Nearly 300 people were affected by the tremors [3]. The quakes destroyed 48 homes in the region [3].
Emergency response teams focused on the Chupaca province to locate survivors and provide medical aid to the 21 injured residents [1, 2]. The mountainous terrain of the Junín region often complicates the delivery of relief services after such disasters.

The occurrence of twin earthquakes in a short window increases the risk of structural failure, as the first tremor weakens buildings and the second causes them to collapse. The high number of destroyed homes relative to the earthquake magnitude suggests that local infrastructure in the Junín region may not meet modern seismic building standards, exacerbating the humanitarian impact of mid-range quakes.
