MEXICO CITY, March 28 (UPI) -- Mexico's Popocatépetl volcano erupted over the weekend, spewing columns of ash up to a mile high.
The most significant of the low-intensity effects occurred on Saturday and Sunday. About 20 minutes worth of tremors were felt in the region, which is southeast of Mexico City.
Mexico's National Center for Disaster Prevention has warned nearby residents to avoid the area, adding that low-level to intermediate-level explosive activity is expected. Falling ash may affect nearby towns.
The volcano is in the states of Puebla and Morelos, 43 miles southeast of Mexico City.
A 7-mile exclusion zone has been declared around the volcano, which was relatively quiet Monday.
