The National Emergency Commission had earlier evacuated seven families because of gas and ash eruptions at Turrialba, placing them in subsidized housing until the mountain’s unrest ends.
A total of 40 people fled their homes during early January as the volcano displayed its most intense activity in more than 140 years.
Vulcanologists have assured nearby residents that the mountain does not appear ready to expel lava at this time.
The mountain has become increasingly active since it began to awaken in January 2001.
Turrialba’s acidic gas emissions caused burns to local crops and pastures during 2008 and 2009.
