Landslides caused by a flash flood destroyed several houses in Aguas Calientes, the town nearest the famous archeological site of Machu Picchu, and buried the railway line near the entrance to the site. One person was known to have died and at least 500 tourists were evacuated by helicopter. No tourists were injured or missing, and Machu Picchu itself was not damaged. By April 13 the railroad tracks had been cleared and rail service had resumed, but rescue workers were still searching the rest of the landslide for survivors.
