Overview
- Peru’s geophysics institute reported a magnitude 4.3 quake in Ucayali, 34 km south of Curimaná at 131 km depth, felt at intensity III with no damage or injuries.
- Mexico’s national seismic service logged a magnitude 4.0 northeast of Matías Romero in Oaxaca and a 3.7 west of Puerto Vallarta in Jalisco as part of routine activity.
- Mexico City’s public alert did not sound because SASMEX activates only for stronger or closer events, often near magnitude 6 depending on distance.
- Monitoring agencies in the Pacific Ring of Fire — IGP in Peru, SSN in Mexico, and the USGS in the U.S. — post real‑time data on magnitude, depth, and location to guide the public.
- Authorities in both countries urge emergency kits, family plans, and safe construction, noting that deeper quakes like Ucayali’s usually feel weaker at the surface.
