Glaciated Tolima volcano is seen here looking south from the flank of Nevado del Ruiz. The summit consists of late-Pleistocene to Holocene lava domes and contains a crater 200-300 m deep. Holocene activity has ranged from moderate explosions to Plinian eruptions. A recent major eruption took place about 3,600 years ago and minor explosive eruptions took place in the 19th and 20th centuries.
