Caldera del Atuel, Volcanic caldera in Mendoza Province, Argentina.
The Caldera del Atuel extends over 30 kilometers wide and 45 kilometers long, featuring numerous basaltic cones and lava flows in its eastern section.
The formation occurred through intense volcanic activity millions of years ago, resulting in a massive collapse that created the current geological structure.
Indigenous Huarpe communities established settlements near the caldera, using the mineral-rich soil for their agricultural practices and daily activities.
The site remains accessible through Provincial Route 173, with optimal visiting conditions occurring during the dry season between October and April.
Scientists identified surface changes in the caldera following the 2010 Maule earthquake, indicating ongoing geological activity in the volcanic formation.
