Mexico-Guatemala & South American seismic activity

Overview

The region continues to experience significant seismic events. On 17 July 2026, a shallow magnitude 7.3 earthquake struck the Pacific coast near Tapachula, Chiapas, and the adjacent Guatemalan shoreline. Tsunami alerts were issued for Mexico, Guatemala, and El Salvador. Authorities reported no casualties, but cracks appeared in several public buildings in Mexico and minor infrastructure damage was noted in Guatemala. In Peru, the Junín region has been hit by a series of earthquakes impacting the Chupaca and Huancayo provinces. A magnitude 5.0 earthquake centered near Chupaca on 6 August 2026 caused significant disruption, including injuries to at least 15 people and the collapse of over 125 homes, particularly adobe structures in the Canipaco valley. Many of these buildings had already been weakened by a prior magnitude 5.4 earthquake on 18 July. Seismic activity has triggered rockslides and landslides, blocking road infrastructure and transit between districts. The Instituto Geofísico del Perú (IGP) has linked this activity to the reactivation of the Altos del Mantaro fault. By 31 August, a 5.1 magnitude earthquake caused by the reactivation of the Alto Mantaro fault struck Chupaca, causing widespread panic. In response, technical agencies including INGEMMET, IGP, ANA, Cenepred, and Indeci began conducting risk assessments in the southern Mantaro Valley, specifically evaluating ground displacements in sectors like Pumpumya. In early September, Peru recorded three medium-intensity earthquakes, alongside a significant fire on Canevaro Avenue in Lince that required over 10 firefighting units. Throughout September and October 2026, seismic activity intensified across Peru, Ecuador, and Chile. In mid-September, a magnitude 5.5 earthquake near the Peru-Ecuador border was reported by the Instituto Geofísico de Ecuador. Seismologist César Jiménez Tintaya warned of a potential magnitude 8.0+ earthquake due to a seismic gap on the central coast. In late October, seismic activity persisted across South America.
