Tens of thousands of people live in the farming villages on the volcano’s
flanks while roughly 25 million people live within a 60 mile radius.
It is feared the airborne ash could cause havoc with Mexico City’s busy
airport and a large eruption of Popo, as it is commonly known, could see ash
falling on Mexico City itself, around 50 miles away.
Authorities are already preparing evacuation plans and shelters should the
eruptions escalate. The last major eruption forced thousands of people to
flee their homes in 2000.
Local resident Aaron Sanchez Oceloti, 45, described Friday’s eruption. He
said: “Up on the mountain, it feels incredible. It sounds like the
roaring of the sea.”
Scientists have no way of predicting whether how the pressure inside the
volcano’s magma chamber will be released.
They estimate a 35 million cubic foot chamber of magma is seething about six
miles beneath Popocatepetl.
Roberto Quaas, director of the disaster prevention centre, compared the
volcano to a bottle of champagne.
He said: “You could take the cork out quickly and all the gaseous
material and liquid rushes out suddenly, or it could also happen slowly.”
However, he said, “we know that this lava dome, sooner or later, will be
destroyed by internal pressure.”
Scientists have detected fracturing about 3.5 miles (5 to 6 kilometres) down,
accompanied by small earthquakes measuring about 3.4 magnitude, he said.
Popocatepetl began its current round of activity in 1994, with small eruptions
of ash almost daily, but since a powerful explosion in December 2000, it’s
activity has been low until a week ago when the eruptions began growing in
size.
Named after a legendary Indian warrior, the volcano has been a popular tourist
attraction for many years.
People in the village of Xalitzintla said they were awakened by a
window-rattling series of eruptions on Friday.
Mexico’s National Disaster Prevention Center said one string of eruptions
ended in the early morning, then the volcano started up again at 5.05am,
with at least 12 eruptions in two hours.
President Felipe Calderon said on a live national television broadcast that
they were keeping roads open around the mountain, preparing emergency
shelters and making sure residents know the latest information about a
potential eruption.
“It’s our obligation to stay alert, to stay on guard, so we can keep
carefully following developments and have the opportunity to respond
quickly, if needed, and efficiently, to whatever might happen,”
Calderon said
Gregorio Fuentes Casquera, the assistant mayor of Xalitzintla, a village of
2,600 people about seven miles (12 kilometres) from the summit, said the
town had prepared 50 buses and was sending out its six-member police forces
to alert people to be ready to evacuate.
“Everyone needs to take this seriously. This buzzing, this roaring isn’t
normal,” he said, adding that he believed about half the populace would
be willing to evacuate, while the rest would want to stay.
As the quiet of the corn fields and fruit orchards was pervaded by the
volcano’s spooky roaring, dozens of women lined up in Xalitzintla’s main
square to get free face masks and bottles of water.
Health authorities were giving out 10 masks and 10 bottles of water to each
family, and the surgical-style masks, intended to filter out the fine ash
released by the volcano, were becoming common among the town’s students.
“Right now we’re not scared. When it’s scary is at night, when it’s
putting out lava,” said Nancy Agustin Inclan, 14, as she removed her
mask and took a break outside the gate of the town’s middle school.
Webcam images on the site of the National Disaster Prevention Center showed
the plume rising from the top of the peak at dawn, though clouds obscured
the volcano for people further away.
The Televisa television network broadcast images of red, glowing material
rising from the crater and falling on its slopes.
The ash was blowing to the northeast, in the general direction of Puebla.
