In the annals of industrial disasters, one event stands out as particularly devastating yet largely unknown to the wider world: the PEMEX LPG Explosion of 1984. This catastrophic incident, which occurred on November 19, 1984, in San Juanico, Mexico, remains one of the deadliest accidents in the history of the petroleum industry. Despite its magnitude, the PEMEX explosion has received relatively little attention compared to other industrial disasters, such as Chernobyl or the Exxon Valdez oil spill.
The state-owned Mexican oil company, PEMEX, operated a liquid petroleum gas (LPG) distribution facility in San Juanico, a small town located just northwest of Mexico City. LPG, consisting primarily of propane and butane, is commonly used as a fuel for heating and cooking, as well as in industrial processes. At the San Juanico facility, LPG was stored in massive spherical tanks, which held thousands of gallons of highly flammable gas.
On that fateful November day, a series of unfortunate events culminated in a catastrophic explosion that would forever change the landscape of San Juanico. It began when a pump malfunctioned, causing LPG to leak from one of the storage tanks. Unbeknownst to the workers at the facility, the leaking gas quickly formed a highly combustible vapor cloud that enveloped the surrounding area.
As the vapor cloud spread, it eventually encountered an ignition source, triggering a massive explosion that reverberated across San Juanico and beyond. The force of the blast was so powerful that it flattened buildings, incinerated vehicles, and sent debris flying for miles. Shockwaves from the explosion shattered windows and caused widespread structural damage, leaving entire neighborhoods in ruins.
The human toll of the PEMEX explosion was staggering. Official estimates put the death toll at around 500 people, with thousands more injured. However, due to the chaotic nature of the event and the lack of comprehensive record-keeping, the true number of casualties may never be known. The blast also displaced thousands of residents, many of whom lost their homes and livelihoods in an instant.
In the aftermath of the explosion, emergency response teams descended on San Juanico to search for survivors and provide medical assistance. However, the scale of the disaster overwhelmed local authorities, who struggled to coordinate rescue efforts and provide aid to those in need. The lack of preparedness and resources further compounded the suffering of the affected communities.
As news of the explosion spread, the Mexican government faced scrutiny and criticism for its handling of the disaster. Questions were raised about the safety protocols and maintenance practices at the PEMEX facility, as well as the adequacy of regulations governing the storage and transportation of hazardous materials. In the years leading up to the explosion, there had been reports of safety violations and concerns raised by workers about the condition of the storage tanks.
Despite the magnitude of the PEMEX explosion, its impact was largely overshadowed by other major events of the time, both domestically and internationally. In Mexico, the explosion received limited coverage in the media, and the government was accused of downplaying the severity of the disaster. Internationally, attention was focused on other issues, such as the Cold War and geopolitical tensions in the Middle East.
In the years following the PEMEX explosion, efforts were made to improve safety standards and regulations governing the petroleum industry in Mexico. However, systemic challenges, including corruption and bureaucratic inefficiency, hindered progress in implementing meaningful reforms. The lessons learned from San Juanico were quickly forgotten, and similar disasters continued to occur with alarming frequency in the years that followed.

Today, the site of the PEMEX explosion serves as a somber reminder of the human cost of industrial negligence and the need for greater accountability in the management of hazardous materials. Memorials have been erected to honor the victims of the disaster, but for many residents of San Juanico, the scars of that tragic day remain deeply etched in their collective memory.
The PEMEX LPG Explosion of 1984 may be one of the biggest disasters you’ve never heard of, but its impact continues to resonate in the communities that were forever changed by its devastating aftermath. As we reflect on this forgotten tragedy, we are reminded of the importance of prioritizing safety and vigilance in the face of potential dangers posed by industrial operations. Only by learning from the mistakes of the past can we hope to prevent similar tragedies from occurring in the future.
