Abstract


Space geodetic measurements have transformed our understanding of regional tectonics in the North Andes and southwest Caribbean. The Central and South America GPS project, begun in 1988, provided the first direct measurement of subduction at a convergent plate boundary, and it led to the establishment of a global civilian GPS tracking network. Colombia was the center of the 1988 field campaign, and the leadership of Servicio Geológico Colombiano with logistics, training, and personnel was key to the success of the Central and South America project. Early GPS results showed evidence for northward movement of the North Andes, convergence at the South Caribbean deformed belt, rapid Panamá–North Andes collision, and interseismic “locking" at the Colombia–Ecuador trench. Beginning in 2007, space geodetic measurements took a great step forward with GeoRED project, a continuously operating Global Navigation Satellite System network that now has 108 sites providing the first accurate comprehensive model of North Andean Block motion. Recent GeoRED findings include that the North Andean Block is moving to the northeast at a rate of 8.6 mm/y, the Eastern Cordillera is being compressed at a rate of 4.3 mm/y, the Panamá Arc is colliding eastward with the North Andean Block at approximately 15–18 mm/y, and the Panamá–Chocó collision may have been responsible for much of the uplift of the Eastern Cordillera. The new continuous Global Navigation Satellite Systems measurements help quantify tectonic deformation in northwestern South America and the southwest Caribbean, including earthquake hazards at the Colombia trench, the Caribbean margin, the East Andean Fault System in the Eastern Cordillera, and the Panamá collision zone in northwestern Colombia; as well as the deformation of Colombian volcanoes.

 

Keywords: space geodesy, North Andean Block, crustal deformation, Global Positioning System. 



Resumen


Las mediciones geodésicas espaciales han transformado nuestro entendimiento sobre la tectónica regional en los Andes del norte y el suroeste del Caribe. El proyecto Central and South America GPS comenzó en 1988, suministrando la primera medición directa de la subducción en un límite de placa convergente, y llevó al establecimiento de una red de rastreo global civil. Colombia fue el centro de la campaña de campo de 1988 y el liderazgo de Ingeominas (ahora Servicio Geológico Colombiano) con la logística, entrenamiento y personal fue la clave para el éxito del proyecto Central and South America GPS. Los primeros resultados de GPS mostraron evidencia de movimiento de los Andes del norte hacia el norte, convergencia del cinturón deformado del sur del Caribe, rápida colisión Panamá–Andes del norte, y “bloqueo" intersísmico en la trinchera Colombia–Ecuador. A comienzos del 2007, las mediciones geodésicas espaciales dieron un gran paso con el proyecto GeoRED, una red de operación continua del Sistema Global de Navegación por Satélite que ahora tiene 108 sitios y ofrece el primer modelo preciso de movimiento del bloque norte de los Andes. Hallazgos recientes de GeoRED indican que el bloque norte de los Andes se está moviendo hacia el noreste a una tasa de 8,6 mm/año, la cordillera Oriental está siendo comprimida a una tasa de 4,3 mm/año, el Arco de Panamá está colisionando hacia el este con el bloque norte de los Andes a 15–18 mm/año aproximadamente y la colisión Panamá–Chocó puede haber sido responsable en gran parte del levantamiento de la cordillera Oriental. Las nuevas mediciones continuas del Sistema Global de Navegación por Satélite ayudan a cuantificar la deformación tectónica en el noroeste de Suramérica y el suroeste del Caribe, incluyendo la amenaza sísmica en la trinchera de Colombia, el margen Caribe, el sistema de fallas andino oriental en la cordillera Oriental y la zona de colisión de Panamá en el noroeste de Colombia, así como la deformación de los volcanes colombianos.

 

Palabras clave: geodesia espacial, bloque norte de los Andes, deformación cortical, Sistema de Posicionamiento Global.​
