Located about 65 kilometers (40 miles) away from Manila, Taal is one of the country’s most active volcanoes, although it has not had a major eruption since 1977. A catastrophic eruption in 1911 claimed 1,335 lives.
The National Disaster Risk Reduction and Management Council suggested that about 8,000 residents in the area should be evacuated.
Flights have also been temporarily suspended in and out of Manila airport.
Ash reportedly reached as far as the province of Cavite, directly south of Manila. Regional government officials have canceled school classes for Monday and warned residents to stay indoors.
