The giant ground cracks observed in parts of Batangas province this week are similar to the fissures that preceded 2 previous eruptions of the Taal Volcano, the Philippine Institute of Volcanology and Seismology said Wednesday. 

Sitting on the center of a picturesque lake, Taal on Sunday belched a giant ash column that reached Metro Manila and nearby areas, closed the capital's airport overnight, sent thousands to evacuation centers and forced the cancellation of classes. 

Fissures were observed since in San Nicolas, Lemery and Talisay towns in Batangas — a sign that magma is moving towards the volcano's crater, said Phivolcs Director Renato Solidum. 

Similar fissures preceded Taal's eruptions in 1754 and 1911, he said. The 1911 eruption killed some 1,300 people while the one in 1754 lasted for a few months, according to Phivolcs. 
There is "no indication" so far that the new cracks will spew steam or magma, Solidum said. 

Taal on Wednesday continues belching an ash cloud about one kilometer high. It has also spawned some 3,200 quakes, of which 156 were felt, since Sunday, added the Phivolcs chief. 

The volcano remains under the second highest danger level, which means a "hazardous explosive eruption is possible within hours to days," said Phivolcs.
