Except the ash cloud, there is not risk for the human population because the volcano is not located near a populated area. Wolf had been inactive 33 years. Actually, the lava is flowing down the volcano’s southern face while the iguanas, officially an endangered species, inhabit the opposite side, the Environment Ministry said in a statement. The actual eruption of volcano was preceded by unusual seismic activity in April. Galapagos pink land iguana (Conolophus marthae) was first discovered in 1986 and is the only evidence of ancient diversification along the Galapagos land iguana lineage. No more than a hundred individuals have been estimated to form the single population which has the single range limited to the Wolf volcano. The volcano was named after Theodor Wolf, a German geologist who studied the Galapagos Islands in the 19th century.
