The Sierra la Primavera volcanic complex is located immediately west of México's second-largest city, Guadalajara. Following the eruption of rhyolitic lava flows and domes beginning about 120,000 years before present (BP), an 11-km-wide caldera was formed as a result of the eruption of the 20 cu km Tala Tuff about 95,000 years BP. La Primavera caldera subsequently filled with water, forming a lake, through which several lava domes were emplaced. The eruption of a series of older ring domes along the margin of the caldera about 95,000 years ago was followed about 75,000 years ago by the eruption of a younger series of ring domes. Uplift and sedimentation filled the lake, and a final series of lava domes was erupted along the southern margin of the caldera beginning about 60,000 years BP. The youngest lava dome was dated at about 30,000 years BP. Steam vents and hot springs currently are active throughout the volcanic complex.
