Authorities in Mexico raised the alert level for the Popocatepetl volcano southeast of Mexico City due to increasing activity. It's now at the fifth step on a seven-level warning scale.
A lava dome is growing in the volcano's crater, the National Disaster Prevention Center said Tuesday. The 17,886-foot (5,450-meter) volcano also has been spewing fragments of incandescent rock recently, as well as water vapour and ash.
The volcano could experience "significant explosions of growing intensity that hurl incandescent rocks significant distances," large ash showers and possible flows of mud and molten rocks down the volcano's flanks, the centre said.
The agency said the area has been closed to visitors and urged people to stay at least 7 miles (12 kilometres) from the crater, which is about 40 miles (65 kilometres) southeast of Mexico's capital. It also recommended people in the surrounding areas clean ash from weak rooftops and to cover their mouths to avoid inhaling it.
The alert is now at the highest level of the yellow stage; the next stage is a red alert, in which evacuations would presumably begin.
Known as "El Popo," the volcano staged its most violent eruption in 1,200 years on Dec. 18, 2000, when an explosion sent up a plume of red-hot rock and forced the evacuation of thousands of people who live at the volcano's base.
Known as "El Popo," the volcano has been erupting intermittently since December 1994.
