In recent days, tremors have occurred in different parts of the earth and despite the intensity of the telluric movements, some people are unable to feel the shakingBut why does this happen?
According to the geologist Armando Espinoza, the answer to why some people do not feel the tremors is due to two factors, one of them is the place where they are and the other the position in which they are.
“We can all feel them the same way. It is not that there are people who feel earthquakes and others who do not. The intensity with which we feel a shaking It depends on the position of the person and the place where he is. That is to say, if you are standing you have less possibility of perceiving it than if you are lying down or sitting you have more possibility”, says the expert to kienyke.
The geologist mentioned that both the intensity and the magnitude of the tremor influence the position of the body and its perception of movement.
He stated that by magnitude it should be understood that it is a quantitative description of the earthquake from the measurement of the energy released by the rupture of a fault, while the intensity refers to the qualitative description of the effects of the earthquake. shaking.
As an example he mentioned that “when you are lying down you have your whole body on a surface in contact with the ground, therefore you feel the movement much more. If you are sitting, the perception is intermediate, but you still have an object of contact, which is the chair. When standing you don’t perceive as much, since your only connection with the ground is your feet and even less so if you’re walking, the action of walking prevents you from perceiving that the ground is moving a little”.
He added that the situation is also linked to the type of earthquake that occurs, since there are some that are very weak, others make the houses vibrate more than the buildings and vice versa.
“On the other hand, some waves shake houses more than buildings, the latter feel more movement due to elastic waves, tension disturbances that spread through the ground,” he concluded.
What to do during an earthquake
As far as possible, stay calm and stay indoors for the duration of the tremor, recommends the Geophysical Institute, in addition to the following:
Drop to the ground, cover and hold on! Take only steps that allow you to get under a safe place, such as a sturdy desk or table. Once there grab hold of one leg with both hands.
Stay away from windows, glass, mirrors, exterior doors or walls, and anything that could fall on you such as lamps and furniture.
If there is no table or desk near you, cover your face and head with your arms and crouch away from windows and bookshelves.
We recommend you read:
If you are in…
The street: stay away from electric poles and wires.
A building: Get under a table or desk, away from windows and outside walls. Stay there until the movement has passed. DO NOT use the elevators.
The interior of a busy place like a restaurant or movie theater: Stay where you are. Don’t run to doors. Stay away from shelves that contain objects that could fall on you.
A moving car: Stop as quickly as possible and stay inside the vehicle until the shaking stops. Avoid stopping near or under buildings, trees, bridges, or power lines.
Then proceed cautiously, watching the road and bridges for damage. If you must go out, watch for falling objects, downed power lines and walls, bridges, etc.
