A volcano erupted early Monday in Ecuador’s Galapagos Islands for the first time in more than 30 years. The eruption raised concerns for the only remaining colony of pink iguanas.

The Galapagos National Park tweeted that Isabela Island, where the 1.1 mile high Wolf Volcano erupted, is home to the “only population” of the critically endangered Galapagos rosy iguana, or Conolophus marthae, in the world. The park later said in a statement that the iguanas, which share a habitat with giant Chelonoidis becki tortoises and yellow iguanas, were situated on a northwest flank.

This “raises hopes that they will not be affected.” Officials said the lava flowing from the volcano Monday was on the opposite side.

Though the iguanas may escape harm, marine life could be in trouble. The flow will likely reach the ocean according to Ecuador’s Geophysics Institute. Sandro Vaca of the Geophysics Institute said that the volcanic activity could continue for several days and potentially cause more lava flows.

A tourist boat passing the uninhabited area informed authorities of the volcanic eruption, according to Telegraph. Then, park officials flew over the area to assess the damages.

The park posted photos of lava streaming from the sides of the Wolf Volcano, the highest point of Galapagos. Reuters reported that the park claimed the volcano had been dormant for 33 years.

The park also stated that the volcano was not located near a populated area and that no humans were in danger. However, the institute said that some of the ash cloud could descend upon populated areas. The island’s inhabitants live roughly 70 miles south of the volcano.

This is not the first unusual seismic activity Isabela Island has experienced this year. Activity was reported on the Sierra volcano in April, which hosts yellow iguanas and turtles.

This news comes just after word of eruptions in Chile. Ecuador and Chile are both located on what is known as the Pacific Ring of Fire.
