Overview
- The IGP recorded three earthquakes near Chupaca between the night of Saturday, August 8 and early Sunday, August 9, with magnitudes of 3.8, 4.3 and a final 3.7 at 03:26 a.m.
- The largest of the recent events was a magnitude 4.3 at 23:05 on August 8, located about 19 km south of Chupaca with a depth near 11 km and estimated intensity III in town.
- Officials report no injuries or material damage from the sequence so far, while residents in the southern Mantaro valley remain on alert because of earlier tremors, including a magnitude 5.0 on August 6 and a July 18 event.
- The IGP continues near‑real‑time monitoring and urges people to keep an updated family emergency plan, identify evacuation routes and have an emergency kit ready.
- Peru’s frequent quakes stem from the Nazca Plate sliding beneath the South American Plate along the Pacific Ring of Fire, a process that concentrates shallow seismic activity in the Andes and near populated valleys.
