This is the startling footage taken from a helicopter above the crater of the active Popocatepetl volcano where a huge dome has been formed by recent eruptions.
The National Centre for Prevention of Disasters (CENAPRED) carried out two flyovers over the volcano with the support of the Federal Police to evaluate the recent activity of the Popocatepetl volcano and measure the emission of gases from the crater.
Popocatepetl is an active volcano located in the states of Puebla and Morelos in Central Mexico.
The observations confirmed the formation of a dome, given the number 82, which is estimated to have a diameter of 200 metres (656 feet).
In the video, the smoking crater of the volcano can be seen with swirls of gas emanating.
Reports state dome 82 could grow in the coming days which could lead to Strombolian eruptions similar to those recently registered at Popocatepetl.
Strombolian eruptions are mild blasts of volcanic eruptions which send lava bombs and incandescent material relatively short distances.
The dome may also be destroyed in a volcanic explosion which would see material launched a further distance and a column of ash form high into the air.
The current signal alert is Yellow Phase 2, which foresees Explosive activity of low to intermediate level, the falling of ash in nearby towns, and the possibility of short-range pyroclastic flows and mudflows.
The name Popocatepetl comes from the Nahuatl language and means ‘Smoking Mountain’. It is also referred to by Mexicans as ‘El Popo’.
