MANILA (2nd UPDATE) -- Several areas in Batangas, as well as Muntinlupa City in Metro Manila, suspended classes on Monday, August 19 due to volcanic smog coming from the Taal Volcano.

The following towns and cities have declared class suspensions:

-- Laurel (preschool to senior high school, public and private)

-- Nasugbu (all levels, public and private)

-- San Luis (all levels, public)

-- Balete (all levels, public and private)

Classes will shift to modular or online distance learning.

Muntinlupa also suspended its Aug. 19 classes in all levels, Mayor Ruffy Biazon announced via Facebook Live. He said students already in class would be sent home.

Local government units have advised the public to wear face masks and stay inside their homes if possible.

Taal Volcano remains under Alert Level 1 which means that it is still in "abnormal condition and should not be interpreted to have ceased unrest nor ceased the threat of eruptive activity."
