The magnitude 7.4 earthquake recorded on July 17 at 08:49 hours off the coast of Ciudad Hidalgo, Chiapas, produced zero casualties and no loss of life, according to the National Civil Protection Coordination (CNPC). The Secretariat of the Navy dismissed the tsunami alert for Mexico's Pacific coast in under three hours, after confirming that no significant sea level variations were expected along the shoreline.
The seismic event, with its epicenter 135 kilometers southwest of Ciudad Hidalgo and a depth of 10 kilometers, immediately triggered civil protection protocols across all three levels of government. The CNPC, led by Laura Velázquez Alzúa, coordinated the response with the Chiapas state government, led by Governor Eduardo Ramírez Aguilar, and municipal units across the state's 15 regions. Governor Ramírez Aguilar ordered a suspension of activities and deployed the full state cabinet, while the National Seismological Service (SSN) revised the preliminary magnitude upward from 6.8 to 7.4 following definitive analysis. The coordination among federal, state, and municipal authorities enabled damage assessment and population assistance to begin within the first hour after the earthquake.
As of the CNPC's official update, 60 aftershocks had been recorded, the largest reaching magnitude 6.5. State brigades evacuated 4,480 people in coastal municipalities, and minor non-structural damage was recorded in 36 homes, 7 schools, and 3 hospitals, concentrated in Tapachula and Suchiate. The Federal Electricity Commission (CFE) confirmed that electrical infrastructure sustained no damage, allowing service to be maintained throughout the region. The state government reported four people with minor injuries and 18 total medical consultations, with no loss of life.
Aftershock monitoring continues as brigades from all three levels of government carry out structural assessments of homes, schools, and health facilities in the affected areas. The simultaneous activation of federal, state, and municipal protocols, combined with the timely evacuation of the population, demonstrates an interinstitutional coordination model that reduced the human impact to zero in a major earthquake.
