An Oil City Underwater
The city of Poza Rica, a vital urban center for the energy industry in the north of Veracruz, is mired in a critical emergency after the overflowing of the Cazones River. The hydrometeorological event has generated scenes of extreme vulnerability, where the population has been forced to face the relentless force of nature. Visual testimonies, widely disseminated on digital platforms, document the seriousness of the situation: a minor clinging to the top of a tree, pleading for help while the current roared around him, and an adult man on the roof of his car, swinging over the murky waters that flooded main roads in a matter of hours.
The sudden flow was not an isolated phenomenon. Hours before the disaster, the Gulf Central Basin Agency of the National Water Commission (Conagua) issued a technical alert about the imminent overflow of the river. Hydrological models indicated that strong runoff from the upper parts of the basin had suddenly raised the levels of the tributary by more than two meters. Despite this expert warning, the crest of water reached the urban area during the early hours of Friday morning, taking thousands of residents by surprise, many of whom report not having received effective official notification that would allow for an orderly evacuation.
Immediate Impact and Emergency Response
The urban infrastructure of Poza Rica suffered a partial collapse. The Bus Station, a transportation hub, was submerged, as were numerous businesses, including chain establishments such as an Oxxo, whose facilities were completely engulfed by the current. Private vehicles and public transportation units were dragged as if they were toys, evidencing the hydraulic power of the event. During the most critical hours, the absence of rescue boats from the Army, Navy or State Police was notable, creating an operational vacuum that was initially filled by neighborhood solidarity. Direct institutional help for the hundreds of people trapped on roofs and rooftops arrived hours after the catastrophe began.
The magnitude of the disaster extends beyond Poza Rica. At least 48 Veracruz municipalities reported various types of damage due to the intense rainfall recorded in the last 72 hours. The city of Alamo also took a severe hit, with approximately five thousand homes impacted by the flooding of tributaries. However, while in Álamo the water levels began to decline relatively quickly, in Poza Rica the withdrawal of the flow of the Cazones River has been described as “desperately slow”, prolonging the agony of those affected and making damage assessment and rescue work difficult.
Technical Analysis and Hydrological Context
From a technical perspective, this event is not simply a “flood”, but an extremely fast and voluminous avenue of water. The Cazones and Pantepec rivers, which converge in this region, function as natural collectors of runoff from other entities in the country. The intense rains in the high areas of the hydrographic basin generated a volume of runoff that the natural channels could not contain, leading to a phenomenon known as “water stroke” or torrential flood. This process explains the observed sequence: first, street flooding due to local precipitation; then, flooding of crops and riverside homes; and finally, the flooding of large urban areas due to the arrival of the mass of water accumulated upstream.
The consequences in rural communities are equally devastating. State authorities have reported significant damage in 41 rural communities, with roads closed due to landslides and entire towns cut off. This creates a double crisis: attention is focused on the visible urban emergency, while rural areas face a critical lack of communication that delays the arrival of food and medical assistance. The official preliminary balance reports two deaths: a police officer from Papantla during rescue efforts and a doctor swept away by the current in the central area of the state, but federal, state and municipal authorities are still unable to quantify a definitive number of injuries or fatalities in the municipality of Poza Rica, which underlines the complexity of the operation.
Faced with this disaster situation, the armed and security forces have activated their emergency protocols. The Mexican Army maintains the Plan DN-III-E operational, specialized in civil protection tasks and assistance to the population. In a coordinated manner, the Ministry of the Navy applies the Marine Plan and the state Ministry of Public Security deploys the Tajín Plan. The effectiveness of this large-scale coordinated response is being tested against an event of this magnitude, which has overwhelmed local prevention and early response mechanisms, raising serious questions about risk management in regions with high exposure to extreme hydrometeorological phenomena.
The tragedy in northern Veracruz is a stark reminder of the vulnerability of human settlements to the force of nature and the critical importance of early warning systems and evacuation protocols.
