A volcano that started erupting on one of the Galapagos Islands last week may be changing the landscape of the island.

According to the Associated Press, rangers and tour guides spotted lava flowing down the northeastern flank of the Cerro Azul Volcano on the Island of Isabela late on Wednesday. The volcano had erupted last Thursday through Sunday as well.

"What we saw during the flight was a rather big fissure, approximately 437 yards long, that was spewing magma approximately 66 yards into the air."

Scientists feel the volcano may be changing the geography.

"We saw that, for example, the blue lagoon that was in the crater before is no longer there, the green lagoon is somewhat dry, and we also detected a volcanic vent."

Cerro Azul, one of five active volcanos on the island, last eruputed in September 1998, causingminor damage to plant life. The volcano is located on the unpopulated southwestern corner of the island. The Galapagos Islands are known for unique plant and animal life, and it's part of the inspiration for Charles Darwin's theory of evolution.
