Taal Volcano's main crater has been spewing three to five-meter-high geysers of muddy water since Friday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported on Tuesday.
"Mud geysering has continued since Friday but the volcano stays at Alert Level 1," said Allan Lusa, Phivolcs science research specialist at the Taal Volcano Observatory.
In its Saturday advisory, Phivolcs said the muddy water flowed from the north northeastern portion of the main crater.
A similar event, which was recorded in November 1999, lasted until February 2000, according to the Phivolcs.
No other advisories were issued since Saturday, said Lusa.
Phivolcs, meanwhile, advised the public to be vigilant and observe precautions when visiting the volcanic island.
Taal Volcano, known as the smallest active volcano in the world, is located about 70 kilometers south of Manila on an island inside a lake called Taal Lake. What makes Taal Volcano more unique is the fact that the volcano itself has a lake of its own inside its crater which is called the "Crater Lake."
