| Resumo: | The digital-elevation model have been made using the topographic map. The model shows follo-wing mega-features 1) Gentle denudational slopes, located towards south and west of Barva volcano. The drai-nage pattern is radial and this mega-feature is formed by recent pyroclastics that overlays lava flows. 2) Strongdenudational slopes, located towards east of Barva volcano, the drainage pattern is radial and parallel and thetopography is abrupt and eroded, probably ancient, formed by a possible debris avalanche. Another mega-fea-ture is Alajuela Fault, a inverse fault that produced a recumbent fold. This fold is represented by a high scarp. |
