29 F Recents: –Because they occurred toward the end of the XIXth century and the XXth century. These eartquakes, from the Borde de Llanero Fault, occurred in 1917 and 1995 and in the region of Atrato Medio-Tapon del Darien in 1883, 1903 and 1992. F Difficult: –Because of the intrincate geography, the hostile regions and the lack of scientific research in the area, it offers an intriguing challenge for macroseismic observation.
