On January 20, 2001, a powerful earthquake struck the coastal region of Peru, with a magnitude of 7.9. The quake caused widespread destruction in the cities of Arequipa, Moquegua, and Tacna, killing at least 100 people and injuring thousands more. Buildings, roads, and bridges were destroyed, and large areas were left without power or water. The earthquake also triggered landslides, further hampering rescue efforts in the affected areas. In the aftermath, international aid was sent to help with recovery efforts, and the event highlighted the need for improved seismic safety measures in the region.
