Volcano near quake-struck Mexico City belches burning rocks

Popocatepetl, whose name means "Smoking Mountain" in the native Nahuatl language, showered a village at its base with ash, shook with the force of a 1.8 magnitude earthquake and spewed flaming rocks to distances of up to 1 km (0.62 mile), the National Disaster Prevention Center (Cenapred) said.

Eruptions and exhalations take place on average about twice a year since the volcano reactivated 23 years ago and are not seen by disaster officials as a major threat, but the activity has worried Mexicans following the 7.1 magnitude earthquake eight days ago and a series of aftershocks since.

The earthquake had its epicenter just a few miles from the volcano and "probably pushed" the volcanic activity, Carlos Valdez, director of Cenapred, told Reuters. He said the explosions had calmed since dawn.

On a clear day, Popocatepetl looms on the horizon of Mexico City 44 miles (71 km) away, and volcanic ash occasionally blows into the city.

Cenapred recommended people living near the volcano prepare for a possible evacuation order under a phase two yellow alert, two stages from a maximum red alert.

Winds blew the ash on Wednesday towards Ecatzingo, a village under the volcano that suffered damage to its church and dozens of houses in last week's quake. The epicenter of the quake was just a few miles to the southeast of Ecatzingo in the state of Puebla.

The death toll from the earthquake reached 337 on Wednesday, with dozens more victims still believed to be beneath the rubble of one collapsed building in Mexico City.
