According to the National Geographic Institute (IGN), Argentina moves about 2 centimeters per year towards the northwest. It is a geological displacement invisible to the human eye but perfectly measurable with satellite technology.
Tectonic Plates and Their Impact on the Territory
The reason for this geological movement lies beneath our feet. The Earth’s crust is divided into tectonic plates, huge rock blocks that float over the Earth’s mantle and move like rafts on a dense liquid.
Argentina is part of the South American Plate, which interacts with other plates, such as the Nazca Plate, which subducts under the South American Plate in a process known as subduction. This phenomenon generates:
- Earthquakes in regions such as Cuyo and the Argentine northwest.
- Elevation of the Andes mountain range.
- Millimetric but constant displacements.
Consequences of Geological Movement
Although this movement won’t lead Argentina to end up in Peru in a couple of centuries, it does have concrete implications.
- Updating of geographical maps: the Argentine Geodetic Reference System (POSGAR) must be adjusted periodically.
- Correction in satellite navigation (GPS), as reference points change over the years.
- Greater understanding of seismic activity, crucial for urban planning and structural engineering.
A Land in Transformation
This phenomenon reminds us that Argentina is always in motion, geologically and in other aspects.
Knowing that even the ground beneath our feet is constantly changing invites us to rethink our roots, our destinies, and our way of positioning ourselves in the world.
It’s not a metaphor or a poetic exaggeration: Argentina is moving, and we are not talking about politics or sports, but about pure geology.
