With Costa Rica's Turrialba volcano exhibiting low but steady seismic activity, authorities in the Central American nation have raised the alert level from green (normal) to yellow (advisory) and expanded the area of evacuation to about a three-mile radius from the mountain, which is located 25 miles east of the capital city of San Jose.
Vanessa Rosales of the National Emergency Commission said Wednesday during a news conference that "intense but low" seismic activity was continuing in the crater area.
The 10,919-foot volcano erupted briefly Tuesday, spewing ash and rocks and forcing a small number of nearby residents to leave their homes. More evacuations were ordered Wednesday. It was the first eruption since 1866.
