. Laguna Colorada is a wide ignimbrite shield that was formerly also known as Panizos (not to be confused with Cerro Panizos. The shield is not clearly associated with a caldera but appears to contain a sag structure. The ignimbrite field is bordered by the Laguna Colorada to the west, Cerro Torque in the north and Quetena to the east; Laguna Colorada is also the origin of the name of the shield. Likewise, the "Tatio

originates from eruptions at Laguna Colorada; the 700,000 years old Tatio ignimbrite however is considered to be separate. An older ignimbrite was erupted 2.21±0.05 million years ago. An ignimbrite is associated with Laguna Colorada. This ignimbrite was erupted 1.98 million years ago and has a volume of dense rock equivalent, covering a surface of about . Several fall deposits occur both within and below the ignimbrite. This ignimbrite is also known as the Tatio ignimbrite and given a volume of dense rock equivalent, or the Aguadita tuffs. The ignimbrite is one of the youngest in the region and keeps a noticeable texture in high altitude images. Deposits perhaps correlated to this ignimbrite have been recovered in the Quebrada de Humahuaca region. The active geothermal fields of

project was underway at Laguna Colorada. An electrical conductivity anomaly beneath Laguna Colorada has been interpreted either as new magma or hydrothermally altered material. Recent satellite imagery has shown that Laguna Colorada is subsiding at a rate of , with the subsidence encompassing the area of the Laguna Colorada ignimbrite and covering a diameter of .
