Sairecabur volcano is the youngest volcano in the chain; Escalante is also young but not as young as Sairecabur. There are no reports of contemporaneous activity nor has fumarolic activity been reported, although fumaroles and hot springs were found at the shores of Laguna Verde which border on Sairecabur. Future activity at Sairecabur may disturb activity at Atacama Large Millimeter Array.
