The Atacama Desert forms one of the major hyper-arid deserts of the world and it is known to be the driest place on Earth. The extreme aridity of the climate and unusual mineralogy of the regolith in the Atacama region is of considerable interest because of its value as an analogue to the Martian surface. The sedimentary succession in the Atacama Desert records deposition under an arid to semiarid climate from the late Jurassic (150Ma) to the present day (Hartley‚ 2005). Comparison with other long-lived

refer to the landform created by the solidified lava and fragmental volcanic debris that accumulate near the vent. One could say‚ for example‚ that large lava flows are erupted from Kilauea volcano in Hawaii‚ the world volcano here signifies a vent. Volcanoes are not the realm of any single scientific discipline. Rather they require study from many scientists from several specialties: Geophysicist and Geochemist to probe the deep roots of volcano; Geologist to decipher prehistoric volcanic activity;

The island lies in the Pacific Ring of Fire that is characterized by having active volcanic and tectonic activity. Due to its geomorphology‚ the area is very vulnerable to environmental hazards such as earthquakes‚ tsunamis‚ and volcanic activity. The country lies atop 4 converging
