Colombia’s propensity to experience seismic movements is due to its geographical location in the northwestern region of South America., where various tectonic plates such as the Pacific, South American, Nazca and Caribbean plates converge. This location not only impacts the country’s biodiversity and topography, but also increases the likelihood of seismic activity. It is recommended to consult the most recent report of the Colombian Geological Service (SGC) available at this link to obtain updated data on the last recorded earthquake.
Recently, the importance of keeping the Colombian population well informed about seismic activity throughout the nation has been highlighted, urging them to take the necessary precautions to prevent possible damage. In this period, several earthquakes of low and moderate magnitude have been recorded.
Earthquake preparation is a responsibility shared by society. In this sense, the Geological Survey plays a fundamental role in collecting and sharing information on seismic activity at the national level. By being aware of this data and following safety guidelines, we actively contribute to reducing risks and protecting our lives.

What is the Colombian Geological Survey?
The Colombian Geological Service (SGC) is a government entity in charge of studying and generating information about the geological resources and geosciences of the country. Its main mission is to contribute to the knowledge of the Colombian territory through geological research, the evaluation of geological risks and the sustainable management of natural resources.
In this sense, the Colombian Geological Service plays a crucial role in the development of the country by providing key geoscientific information for decision-making in various sectors, including natural risk management, territorial planning and the sustainable use of natural resources. Some of its functions include:
- Geological investigation: carries out geological studies to understand the geological structure of the country, the distribution of mineral resources, the identification of geological risks such as earthquakes, volcanoes, landslides, among others.
- Monitoring of natural threats: is responsible for monitoring natural phenomena such as earthquakes, volcanic eruptions, mass movements and other geological events that may represent threats to the population.
- Geological resource management: evaluates and manages the country’s geological and mineral resources, providing valuable information for sustainable development and decision-making in the economic and environmental sphere.
- Geological cartography: prepares geological maps that represent the distribution of different types of rocks, minerals and other geological elements in Colombian territory.
What is an earthquake or tremor?
An earthquake, also called an earthquake or tremor, is a natural event in which the Earth suddenly releases energy in the form of seismic waves. This energy release is usually the product of the fracture of rocks in the Earth’s crust, caused by the prolonged accumulation of tension. When these rocks break, they emit seismic waves that expand from the point of rupture, generating vibrations on the Earth’s surface.
How do earthquakes originate?
Earthquakes can originate naturally, as a result of tectonic activity at tectonic plate boundaries, or they can be caused by human actions, such as the extraction of resources such as oil and gas, mining, or the injection of fluids into the subsurface.
These events can have considerable impacts on inhabited areas, causing damage to structures, infrastructure and even human losses. For this reason, constant research and monitoring is carried out to better understand them and develop risk reduction strategies.
How are earthquakes measured?
The magnitude of an earthquake can vary, from almost imperceptible movements to devastating earthquakes. The magnitude is measured using the Richter scale or the moment magnitude scale, relating it to the amount of energy released. On the other hand, intensity is evaluated using the Mercalli scale and is associated with the effects observed on the surface, such as damage to buildings and people’s perception.
Differences between an earthquake, tremor and earthquake
The fundamental differences are found in the magnitude and intensity of the seismic movements. The term “earthquake” covers any type of earth movement, while “tremor” usually refers to seismic movements of smaller magnitude, and “earthquake” describes larger seismic events with more serious consequences. Exact designations may vary by geographic region and local conventions.
Prevention measures in case of an earthquake
Preparation becomes crucial despite the impossibility of predicting exactly when the next earthquake will occur. Experts highlight the importance of having an evacuation plan, having emergency kits on hand and knowing safe areas both inside and outside buildings.
Emergency kits should contain items such as water, non-perishable food, a battery-powered radio, flashlights, basic supplies of medications, and copies of important documents. In addition, the importance of educating all family members, including children, about the actions to take before, during and after an earthquake is emphasized.
The importance of being prepared for an earthquake
The importance of being prepared for earthquakes is fundamental, even when it is impossible to accurately predict when the next earthquake event will occur. Specialists emphasize the need to have an established evacuation plan, have emergency kits and know safe areas both inside and outside buildings.
Essential items such as water, non-perishable food, a battery-powered radio, flashlights, basic supplies of medications, and duplicates of relevant documents should be included in these emergency kits. In addition, the importance of educating all family members, including children, about the measures to follow before, during and after an earthquake is highlighted.
