The picturesque Mayon volcano continued to spout spectacular fountains of ash into the sky amid a series of minor eruptions, heightening concerns that a major explosion could occur at any time.
Earthquakes inside Mayon also increased due to the enormous pressure of the ever-increasing amount of lava on its slopes, according to the government's volcanology institute.
"The important thing is that people should not be in those danger zones when a hazardous explosion happens," said chief government volcanologist Renato Solidum.
The so-called danger zone is a radius of six to eight kilometres (3.5 to five miles) from Mayon, and nearly 50,000 people have been evacuated from those areas since the volcano began spewing lava on Monday.
