Story highlights At least 100 people who live near the volcano have been evacuated

Fuego Volcan is one of Central America's most active volcanoes

(CNN) An eruption of Guatemala's so-called "fire volcano" has closed an airport and forced the evacuation of at least 100 people.

Guatemala's national disaster agency says the volcano, known locally as Fuego Volcan, erupted Saturday and spewed ashes "to an altitude reaching 5,500 meters (18,000 feet) above sea level."

The smoke and ash forced Guatemala's La Aurora International Airport to stop all air traffic around the area.

Guatemala's alert level has been raised to "orange," which puts in place the possibility of rescue operations, the disaster agency said.

The volcano is near the Pacific Ocean coast about 60 miles from the capital, Guatemala City.
