In response, the Colombian Geological Service (SGC) clarified this situation and provided some details on how this time is measured. Apparently, this question has three answers, since one thing is how long people feel it, how long instruments record it, or how long the movement of the fault that causes it lasts.

To monitor seismic activity, the SGC uses seismometers, which are capable of recording ground movements that people cannot perceive. That is why the SGC assures that "while a person may feel an earthquake for a few seconds, the stations can record its waves for several minutes." That is why in Colombia, several earthquakes occur daily that people do not feel. "That can vary from person to person. It depends on factors such as the distance to the hypocenter (the place inside the Earth where the rupture begins), the characteristics of the terrain, and the building we are in," they assured. Apparently, the ground where the seismic movement occurs also matters. In terrains made up of more rigid rocks, "seismic waves tend to be less amplified." In some softer soils, "they can amplify the movement and make it perceived for a longer time." According to the SGC: "In the case of the San José del Palmar earthquake, the monitoring stations closest to the epicenter recorded approximately between 90 seconds and 2 minutes of significant movement." However, the entity assures that it has received reports that some people felt it for longer. Developing...
