... in the Bogotá basin, Colombia. By analyzing the earthquake ground‐motion data recorded in Bogotá, it is found that long‐period ground motions with a period of 2 s from shallow earthquakes are strongly amplified within the basin, possibly as a result of the generation of surface waves at the basin edge, whereas...

... accumulations of hydrocarbons in the onshore Llanos Basin of Colombia are characterized by a central zone (Casanare province) with greater than 20° API gravity oils and a southern province with biodegraded, less than 15° API gravity oils. To date, no conceptual model successfully explains this spatial zonation...
