Overview

  • The earthquake struck Friday, July 17, 2026, offshore near Puerto Madero/Aquiles Serdán and was measured at about magnitude 7.3 after an initial 7.4 reading.
  • Seismic agencies reported the shock was shallow at roughly 10 km depth, a factor that produced strong local shaking and raised the chance of coastal tsunami waves.
  • The Pacific Tsunami Warning Center and US NWS issued warnings and advisories for coasts within about 300 km, forecasting local sea rises of roughly 0.3–1.0 metres while ruling out threat to the US and Canada.
  • Dozens of aftershocks followed, some reported in the mid‑6 range, prompting building evacuations, school suspensions in parts of Guatemala, and ongoing inspections by Mexican and Guatemalan authorities.
  • Early official checks found no major structural damage or deaths but local agencies reported a small number of injuries and urged residents to avoid beaches as surveys and monitoring continue.
