Two volcanoes in Mexico erupted Saturday, spewing ash and smoke over surrounding areas.
Colima Volcano was seen shooting ash 2000 meters into the air, and covered nearby villages with volcanic dust. The volcano has been showing signs of increased activity since July 10, when it last erupted.

The volcano is generally viewed as the most active in North America.
Another volcano, Popocatepetl, also continued to bellow gas and vapor Saturday. According to authorities, the volcano has expelled gas and vapor at least nine times in the past three days. Dubbed El Popo by locals, the volcano has intermittently rumbled since 1994, when it suddenly came back to life after five decades of silence.

Authorities say they are closely monitoring both volcanoes, and already have emergency prodceedures in place if they become more active.
