Tremor in Colombia, Friday May 3, 2024: earthquakes reported by the SGC

Two earthquakes of more than 8 degrees have been recorded in the history of Colombia

The first of these events, for which records exist, was an earthquake that struck Cúcuta in 1875, known as the Andean earthquake, which occurred on May 18 of that year and had an estimated intensity between 7.5 and 8.5. on the Richter scale. This earthquake not only affected Cúcuta, but also caused damage in the state of Táchira, Venezuela.

Several factors can cause earthquakes

  • Tectonic: This type of earthquake occurs due to movements in cracks or fractures in the Earth’s crust, as well as at the boundaries between tectonic plates. These movements are the result of the natural adjustment of the Earth’s crust due to the energy accumulated by geological processes.
  • Magmatic: These earthquakes are caused by magma activity in the Earth’s crust, which is related to volcanic activity. Movements and changes in magma pressure can cause seismic tremors.
  • Anthropic: These earthquakes are the result of human activities, such as the construction of large reservoirs that change the pressure on the Earth’s crust, extensive mining extractions that change the geological structure, or the injection of water and rock fracturing in oil exploitation areas. that can cause seismic movements.

What is the reason for the frequent seismic activity in the country?

Due to its location in the Pacific Ring of Fire, Colombia is identified as a country with high vulnerability to earthquakes. This area is the site of approximately 75% of the Earth’s volcanoes and is the site of 80% of the world’s most intense earthquakes.

The country lies within two major subduction zones, where the Nazca tectonic plate collides with the South American plate, and the latter in turn interacts with the Caribbean plate, causing frequent seismic movements.

Therefore, the regions of Nariño, Chocó, Caldas and Santander are the ones most affected by this seismic activity.

What to do in an earthquake: a practical guide to staying safe

Although it is very complex to know when and where an earthquake can be registered, the Ungrd indicated that it is possible to know safety and care measures that can be implemented and that are available to prevent possible emergencies.

According to the National Unit for Disaster Risk Management (Ungrd), an earthquake is the sudden release of large amounts of energy, represented by waves moving through the interior of the Earth and which can be observed by humans upon reaching the surface. animals and even structures.

This is how you activate Google’s earthquake alarm on your mobile phone

This is the path that will work for many if you have an Android device, but remember that it depends on the brand of the phone and the customization layer it uses. So these instructions should be followed:

2. Select the System & Emergency option.

3. Earthquake warning appears at the bottom.

4. When you enter, there is the activation button.

If you enable the feature, Google may request location access and other permissions. It is necessary to give them to them because this will be the way they determine that we are close to seismic activity and generate the alert.

How is an earthquake different from a tremor?

The terms ‘earthquake’ and ‘earthquake’ basically refer to the same natural phenomenon: the sudden movement of the Earth, caused by the release of accumulated energy due to the collision of tectonic plates. The main difference between the two concepts lies in the intensity of the phenomenon.

Although an earthquake can refer to any type of motion, whether mild or strong, an earthquake is used to describe higher intensity seismic movements that often cause significant damage.

In practice, both terms are used interchangeably, but the main distinction arises from the impact caused by the seismic event.

The measurement of its intensity is carried out through the Richter scale, where movements with a force of less than 3 are generally imperceptible to humans, and movements with a force of more than 7 can cause serious damage in inhabited areas.

In the event of earthquakes on high floors, this is what you need to do: pay attention

The first recommendation from the National Disaster Risk Management Unit is to protect yourself and remain calm at all times, as this will allow you to act more safely and appropriately.

Once you determine that it is a tremor or earthquake, follow these tips:

  • If you are in an earthquake-resistant building, stand near columns, under a desk, or in areas marked as safe, and always away from glass or elements that could fall.
  • Never use elevators to evacuate, wait until they are ready and use the stairs.

  • Do not stand under the door frames, this is not a safe place; the frame helps dissipate the earthquake’s energy, which can cause it to break and collapse.
  • When you are at home, and only if possible, open the main and bedroom doors as they can get stuck and lock you and your family in.
  • If you are lying down and cannot get to a safe place, stay in bed or on your side and protect your head with your arms or a pillow.
