Ambato Department

According to some authors, its name comes from the Kakán expression An-Huatu, which means "high sorcerer," and is related to the highest hill in the area, the Manchao hill. Other versions suggest that it comes from the Quechua word Hamppatu or Ampatu, which means "Toad Hill". == Relief and Climate ==

The department entirely features mountainous relief, typical of the Sierras Pampeanas region. The highest point is the Manchao hill (4500 m above sea level). Within Ambato is the source of the Valle river and most of its basin, formed by various rivers and streams. Ambato falls within the arid climate region of mountains and basins, but the numerous watercourses create a more humid microclimate, with average annual precipitation of 350 mm, primarily during the summer months. These conditions favor the development of abundant mountain vegetation. == Population ==

It has a population of 4463 inhabitants (INDEC, 2010), representing a decrease of 1.4% from the 4525 inhabitants (INDEC, 2001) recorded in the previous census. == Seismic Activity ==
