Thousands of people have been evacuated from surrounding villages after the Philippine authorities have warned that the most active volcano in the country may break out in weeks or even days, writes Guardian. The alert level was raised to triple degrees.

The volcano has been hampering nearby villages on Saturday, and lava flows have also been observed. The authorities advised people to cover their mouths and nose. Airplanes can not fly near the volcano.

Mayon, located 330 km southeast of Manila, south-east of Manila, has recorded more than fifty times in the last four centuries. The 2,500-meter high volcano caused 1200 people to die in 1814 and bury a whole city with hot volcanic sludge. The volcano came into operation last time in 2009.
