Portoviejo is a canton that faces various hazards, including floods, landslides, earthquakes, sinkholes, and more. Flooding is the most frequent hazard, caused by natural events such as annual winter seasons or specific phenomena like the El Niño Southern Oscillation (ENSO), which has a recurrence period of 2–7 years. The Decentralized Autonomous Government of Portoviejo holds geographic information and flood hazard data in layer format since 2019, classifying flood risk as follows: RIA (High Flood Risk), RIM (Medium Flood Risk), RIB (Low Flood Risk), and NO RISK. Additionally, they collect information on events occurring in the city through EVIN (Initial Needs Assessment) records and reports from the same year.
