La Agencia Espacial Europea (ESA) reveló ayer una imagen satelital que muestra la terrible dimensión del terremoto que sacudió a Chile el pasado 16 de septiembre. A través del uso de la técnica de radar interferométrico de apertura sintética (InSAR), los especialistas han podido combinar imágenes de antes y después del sismo en un mapa llamado interferograma.

Estos escaneos fueron realizados por el radar Sentinel-14 el 24 a de agosto y el 17 de septiembre, apenas un día después del terremoto, informó la ESA en su página web.

Otro dato revelador es que la magnitud del desastre provocó un desplazamiento de terreno de casi 1,5 metros.

Las franjas en formas de arco iris en el mapa, han ayudado a los científicos a entender hasta qué punto se movió el suelo debido a la magnitud del sismo. De esa forma, han calculado que el terreno se desplazó 140 centímetros. Además, el radar detectó un movimiento horizontal de 0,5 metros a lo lardo de la dirección de su vuelo.

El pasado miércoles 16 de septiembre, un terremoto de 8,4 grados sacudió Chile, provocando un tsumani, dejando un número de 610 personas damnificadas y más de 170 viviendas destruidas. Además, al menos 13 personas perdieron la vida, mientras que otras 20 resultaron heridas.
