Over 9.8 Million Peruvians at Very High Risk of Earthquake: Identifying Vulnerable Zones

A stark warning has been issued regarding Peru's seismic vulnerability, with a national assessment revealing that over 9.8 million people, approximately 30% of the population, face a very high risk from a major earthquake. The Center for National Estimation, Prevention, and Disaster Risk Reduction (Cenepred) identified 182 districts across the country as being the most susceptible to severe seismic events.

Lima emerges as the most exposed region, followed by Piura, Ica, Lambayeque, and La Libertad. Within the capital, districts like San Juan de Lurigancho in the east, and Comas and San Martín de Porres in the north, are flagged for high vulnerability. In southern Lima, soil instability is a major concern in areas like Villa El Salvador and Villa María del Triunfo. The neighboring province of Callao also presents significant risks, with reports indicating that about 70% of its buildings were constructed without professional technical guidance.

Compounding these risks is the widespread issue of informal construction practices. Experts estimate that around 80% of buildings in Peru were erected without prior soil studies, and a staggering 71% of homes were built without technical assistance from professionals. This translates to approximately four million vulnerable homes, whose structural integrity could be severely compromised during a major earthquake. Building without assessing ground conditions, proper plans, or professional supervision significantly heightens the likelihood of severe damage or collapse.

In light of this precarious situation, the National Civil Defense Institute (Indeci) reiterates the importance of preventative measures. Specialist Diana Olaya advises the public to identify safe zones both inside and outside their homes before an emergency strikes. The assessment underscores a critical need for improved building standards, urban planning, and public awareness to mitigate the potential devastation of a future earthquake.
