The Popocatepetl volcano spews a cloud of ash and steam high into the air in Puebla May 11, 2012.
Popocatepetl, 50 miles southeast of Mexico City, shook with tremors that belched out four large plumes of ash on Friday night and Saturday morning, the National Center for Disaster Prevention said in a statement on Saturday.
The biggest expulsion shot an ash cloud 2.5 miles into the air and launched glowing rocks more than half a mile from the crater, the statement said.
Raul Arambula, a scientist collaborating with the government's disaster center, said the volcano threw out the most ash and fragments of red-hot rock since authorities raised the alert level last month.
"It was spectacular," Arambula said. "Of course, it makes you worry about everyone living nearby."
In Santiago Xalitzintla, a village about 6 miles from the volcano, the loud rumblings sent residents running to the town square during the night.
