Why Did Panama’s 7.6-Magnitude Earthquake Claim No Lives?

The magnitude 7.6 earthquake that struck Panama on October 9, 2026 (17 Mehr 1405) left at least 27 injured and about 300 displaced, and damaged more than 400 buildings. The Panamanian government activated its national emergency response mechanism. Critical infrastructure, including the Panama Canal, remained operational, and international partners provided emergency aid.

The earthquake occurred at 12:56 pm local time. Its epicenter was near the remote town of El Pitalosa Arriba, in Herrera province in south-central Panama. The magnitude of the earthquake was initially reported as 8, but it was later revised to 7.6. Its focal depth was also estimated to be about 10 km.

The shallowness of the center was one of the main factors of the intensity of the shaking and the concentration of damages; Because seismic energy experiences less reduction when propagating towards the earth's surface. The Institute of Geosciences of the University of Panama identified the origin of this earthquake as the "Azuero-Soná" fault system in the Azuero Peninsula; An area where tension has accumulated over a long period of time and then suddenly released. This zone is located in the mutual influence of the Caribbean, Cocos, Nazca and South American plates, and its seismic mechanism is mainly characterized by strike-slip faulting. The mechanism of the October 9, 2026 earthquake was also extension slip.

Although Panama is not a region with frequent large earthquakes, there is a significant historical record of such occurrences in the country. The 1882 earthquake was accompanied by a tsunami and affected the San Blas Islands region. The 1962 earthquake with a magnitude of 7.2 occurred near the "Panama Fracture Zone". The Azores Peninsula, the epicenter of the 2026 earthquake, has historically experienced relatively less seismic activity compared to some other regions.

In the October 9 earthquake, initial reports indicated no casualties. About 27 people were injured, mainly due to incidents caused by the collapse of buildings in Veraguas province. About 300 people were also evacuated. Various buildings and infrastructure were damaged. In the town of Penonomé, several buildings collapsed and a church and a hotel were severely damaged. The Panama Canal Management Organization confirmed that the operation of this waterway continues as normal and that there was no structural damage to it. "Tocumen" International Airport was also temporarily closed and evacuated for safety reasons, and flight routes were changed for a short time.

After the main earthquake, more than 80 aftershocks were recorded, one of which had a magnitude of more than 6.6. These aftershocks added to public concern and increased the risk of further damage to damaged structures.

Panama's National System of Civil Protection (SINAPROC), as the legal entity that coordinates crisis management in the country, assumed the responsibility of coordinating emergency measures at the national level and preventive inspections. The president of Panama, "Mulino", described the event as a "major disaster" and the health minister announced the disconnection and isolation of some affected cities, including Tunisia. The Ministry of Education also ordered the closure of classrooms across the country.

It is noteworthy that Panama held its first inter-agency exercise on "Mental Health and Psychosocial Support" (MHPSS) only a few days before the earthquake. About 35 organizations participated in this exercise, and its goal was to integrate psychological first aid in the immediate phase of responding to accidents. This preparedness could provide a framework for relief workers to use in managing acute stress and public panic after an earthquake.

At the request of the Panamanian government, the United States government activated the Disaster Response and Assistance Team (DART) and dispatched two technical Urban Search and Rescue (USAR) teams, consisting of a total of 20 people, to the area. These teams were supposed to be on site within 24 hours of the earthquake and participate in structural assessments and search and rescue operations. The United States also pledged five million dollars in financial aid and allowed the Panamanian Air Force and Navy to use two US-backed helicopters for relief operations.

Why was there no loss of life in an earthquake with a magnitude of 7.6?

The lack of casualties reported in the October 2026 Panama earthquake, despite its high magnitude, should be considered the result of a series of factors; including the remoteness of the epicenter, the relatively low population density in the main area of ​​the earthquake, the concentration of damages in specific areas and structures, and the quick response of rescue forces.

The destructiveness of a 7.6 magnitude earthquake does not depend only on its magnitude; The place of occurrence, the depth of the focus, the distance of the residential areas from the center, the characteristics of the soil and the quality of the buildings also play a role in the amount of damages and casualties. Shallow earthquakes usually cause strong shaking near the earth's surface; However, the severity of the damage depends on the local conditions and the vulnerability of the structures.

The Panama earthquake struck in the middle of the day and many residents were awake. Eyewitnesses described the shaking as intense and prolonged. This tremor in the capital lasted for about 40 seconds and led to the fall of objects and power outages. However, severe structural damage was mainly concentrated in some cities and older buildings and did not lead to widespread collapse of residential buildings across the region.

The vulnerability of part of the building fabric of the affected areas, especially in the central provinces of "Herrera", "Coclé" and "Los Santos", was one of the damaging factors of this earthquake. Many of the buildings in these areas were not designed to withstand strong earthquakes, and the area had not faced an event of this scale before. As a result, churches, government buildings and residential houses were damaged. For example, the cathedral tower of Pennoumeh city and parts of the governor's building collapsed. The earthquake also damaged a number of drinking water treatment plants and caused power outages in six provinces.

Another important factor was the geographical location of the center. The epicenter of the earthquake was located in a low-density area, about 200 kilometers from Panama City. Estimates showed that about 43,000 people lived in areas that were exposed to strong tremors. This figure was much less than the population at risk in some recent earthquakes in the region; These include the twin earthquakes in Venezuela on June 24, 2026, which put an estimated 1.4 million people at risk, and the Colombia earthquake on August 10, 2026, which put more than 1.6 million people at risk.

Along with these factors, Panama's building regulations, especially regarding high-rise buildings in the capital, played a role in maintaining the structural stability of some buildings. Panama City's skyscrapers were largely spared a massive collapse despite strong shaking and residents being evacuated. Compliance with structural standards in such buildings can prevent catastrophic failures in dense urban areas.

The quick response of the National Civil Protection System was also important. By declaring a state of emergency, the government put the closure of schools on the agenda, and relief teams began evacuation operations and damage assessment. The rapid evacuation of buildings, including hospitals and schools, likely reduced the risk of damage from falling debris and overcrowding.

The earthquake occurred at 12:56 pm on Friday local time. Although many people were in buildings at this time, the most severe structural damage was concentrated in cities and specific structures, especially older and underreinforced buildings. Therefore, the lack of reported casualties cannot be attributed to one factor alone; The central location, the dispersion of the population, the quality of the structures and emergency measures, together, played a role in reducing the human consequences of this event.
