UbinasAbout Ubinas
Ubinas is an active stratovolcano in southern Peru’s Moquegua region and is the country’s most frequently erupting volcano. It reaches roughly 5,672 meters in elevation and dominates the local highland landscape.
The volcano is a focus for vulcanological study and for visitors interested in current volcanic phenomena, but public access is restricted during periods of activity. Observers and researchers note frequent ash plumes and intermittent explosive activity rather than long-lived lava flows.
Ubinas has a long record of historical eruptions documented since the colonial period and has produced repeated explosive events in recent decades that have affected nearby villages. Ongoing monitoring and hazard management have been established because of its activity.
Ubinas stands in the Central Andes of southern Peru within Moquegua Department, northeast of the regional towns and surrounded by high Andean terrain.
- Elevation and activity: Rises to an elevation of about 5,672 meters and is the most active volcano in Peru, monitored by national geological agencies.
- Access and safety: Access is limited during eruptive episodes; local authorities issue evacuation orders and restrictions when ash emissions or explosions occur.
