Peru Issues SISMATE Alert for Coastal Rains Through Saturday as Showers Hit Lima’s East

Authorities emphasized that SISMATE is a preventive messaging tool, not an earthquake warning system.

Overview

  • Senamhi’s yellow alert covers the central and southern coast for light to moderate rainfall from January 9–10, with the notice pushed to phones around 1 p.m. and in force until 11:59 p.m. Saturday.
  • Moderate rain was reported Friday in Chosica and Chaclacayo, where the Rímac River’s flow increased and officials urged caution for drivers and pedestrians.
  • Senamhi expects additional showers in Áncash, Lima and Ica in the next hours, with stronger intensity in Lima’s eastern districts than along the western coastline.
  • INDECI clarified that SISMATE distributes preventive alerts for various hazards and does not provide advance earthquake warnings, while a separate SASPE system is under development for significant quakes.
  • Civil defense guidance urges residents to follow official updates, avoid flooded or fast‑flowing areas, secure roofs and gutters, and maintain a stocked emergency kit.
