Large steam clouds hovered over Taal Volcano in the Philippines as it continued to emit gas today.

Footage shows the volcanic vapours floating over the Taal Volcano island and the surrounding lake in Batangas province on June 6.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said in a bulletin today that the smoke columns reached around 1,800 metres tall. The agency warned of possible steam-driven eruptions, minor ashfall, volcanic earthquakes, and lethal accumulation of gases.

Flights have been prohibited from operating 10,000 feet from the volcano's summit due to the threat of phreatic eruptions, the Civil Aviation Authority of the Philippines said.

Pregnant women, children, and the elderly, especially those with underlying health conditions, were also advised to stay indoors as the fumes were hazardous to their health.

Speaking to local media, PHIVOLCS director Dr. Teresito Bacolcol said: 'We remind residents to limit their outdoor activities as much as possible. They have to wear masks if they go outside.

'As of now, Taal Volcano is still under Alert Level 1. It might lead to a volcanic eruption, but it might not. Under Alert Level 1, there is the possibility of a sudden explosion - steam or phreatic explosion. That's why we are closely monitoring the volcano.'

Alert Level 1 is still hoisted over the volcano on June 6.

According to PHIVOLCS, Alert Level 1 indicates 'low level of volcanic unrest'. It warned there may be steam-driven or gas-driven explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas.
