Guatemalan authorities issued a danger warning Wednesday in response to intensifying activity in the country's Fuego Volcano.

The volcano, 50 kilometers (30 miles) southeast of Guatemala City, was belching "fiery clouds" over the course of the day, said David de Leon, a spokesman for the government's disaster response office.

The danger warning issued by the government was one step short of a declaration of emergency requiring evacuation of the communities around the volcano.

He said the mountain has been shaken by explosions that have rattled windows and rooftops and spewed columns of ash to some (5,000) 15,000 feet above sea level.

Guatemala's civil aviation authority was advised to take precautionary measures.

In February, a strong eruption forced authorities to close the international airport because of the falling ash.
