MEXICO CITY,- Mexico's most active volcano Popocatepetl Sunday registered 24 low-intensity eruptions and glowing rocks were seen on the rim of the crater, official sources said.
The National Disaster Prevention Center (Cenapred) said on its website that the volcano, located to the south of Mexico City, caused a series of strong tremors starting from 2:37 a.m. local time (0837 GMT) until almost 7 a.m. (1300 GMT).
Commonly known as "Popo," the Mexican volcano has been especially active in the past three weeks and prompted the authorities to raise the alarm level to "yellow," a step before a "red" alert, under which residents living nearby would have to be evacuated.
Over the past few days, the volcano has been spewing molten rocks, with the majority of them landing on the northern slope. It also shot out a mixture of steam, gas and ash vapor in an easterly direction.
