Nicaraguan authorities have evacuated hundreds of people from the foothills of a volcano because of heightened seismic activity.

The Nicaraguan Institute of Territorial Studies says 600 workers have been moved from a factory near the Telica volcano in western Nicaragua. Women and children who live nearby have also been evacuated.

Institute official Angelica Munoz said Thursday that tremors of up to 3.3-magnitude have shaken the 3,480-foot (1,061- meter) volcano. It has been spewing gas, ash, vapor and water since April.
