The Nazca Slab is a subducted oceanic slab located beneath South America, particularly in the region of the Nazca Plate. This area is of interest to researchers because it provides valuable information about subduction processes, the movement of tectonic plates, and seismic activity in the region. Scientists study the Nazca Slab to better understand the geological dynamics of the region and to improve earthquake forecasting and hazard assessment. Additionally, research on the Nazca Slab can help shed light on the formation and evolution of mountain ranges and volcanoes in the Andes.
