Residents living in San Nicolas de Los Ranchos near Mexico's active Popocatepetl volcano were under a yellow alert on Tuesday, meaning they are ready to evacuate if necessary.
A time lapse video shows the volcano spewing a large plume of ash and gas more than 1.25 miles into the sky on Monday.
The peak is the second tallest in Mexico, after the Citlaltepetl at over 18,000 feet.
