Overview
- The sequence began on Sunday, Aug. 2 with a deep magnitude 5.7 near Aucayacu in Huánuco, Peru, recorded at about 152 kilometers depth by the Instituto Geofísico del Perú.
- Mexican sensors then logged multiple moderate offshore and coastal events in Chiapas and Tabasco, including M4.1–4.6 shocks with focal depths ranging from about 8 to 91 kilometers.
- The most recent notable event was a magnitude 4.5 off Chiapas recorded early on Wednesday, Aug. 5, and authorities say no widespread structural damage or casualties have been confirmed.
- National agencies — the IGP and Mexico’s Servicio Sismológico Nacional — plus Protección Civil and INDECI are maintaining real-time monitoring, routine building inspections, and public preparedness messaging.
- Because the Peru quake was deep and many Mexican events were shallow, shaking varied by location and officials urge residents to follow official channels, check evacuation routes, and keep emergency kits ready.
