Overview
- The Institute of Civil Defense (Indeci) organized the drill on Wednesday to evaluate public response and institutional coordination for a large tsunami threat.
- The Navy’s Hydrography and Navigation Directorate published a hypothetical quake scenario Wednesday, which described an 8.8 Mw shock at 42 km depth with an epicenter 60 km west of Callao based on IGP parameters.
- Sismate sent a local emergency message to mobile phones around 10:05 a.m. warning of an imminent wave train and instructing people to move away from the coast and evacuate to safe, higher ground.
- The exercise activated sirens and routine evacuation steps used across coastal districts, with authorities urging residents to follow evacuation routes and carry basic emergency kits.
- Officials said the test was purely operational with no real event, and they used the results to identify gaps in warning reach, route clarity and interagency messaging that could be fixed before a real tsunami.
