The Popocatépetl volcano is showing the signs of a possible eruption. People are ready to start to evacuate from the area.
The Mexican capital is the world’s fourth most populated city and home to 20 million people, while Peubla has more than 6 million people living there, and all could be at risk in both cites in the event of a catastrophic eruption.
The volcano alert follows fears earlier this month that a second large volcano in Mexico – the 3,850 metres-high Colima in western Mexico – could be about to face a large scale eruption for the first time in 100 years.
Popocatépetl last saw a major eruption in 2000, but early warnings saw 41,000 people evacuated in advance, averting a major disaster.
If the volcano experienced a massive eruption, an estimated nine million people would be in the blast zone and the impact on the atmosphere could be catastrophic.
Popocatépetl has erupted more than 20 times since 1519, according to records.
Research said the world should expect a major catastrophic volcanic eruption in the next 50 to 80 years, but we are woefully unprepared for the fallout.
