As a result of these constant earthquakes, numerous fissures or cracks appeared across different barangays in the Batangas towns of Agoncillo, Lemery, San Nicolas, and Talisay, the towns within the 14-kilometer radius danger zone of Taal. A fissure also transected the road connecting Agoncillo to Laurel. On January 15, the PHIVOLCS reported that the water in Main Crater Lake on Volcano Island had drained; the lake measured 1.9 kilometers wide and above sea level. Portions of the Pansipit River, had also drained as a result of the ground deformation caused by an upward movement of the magma; it was the same process that caused the series of earthquakes. The PHIVOLCS have also hinted at the possible existence of underwater fissures in Taal Lake into which the water may have drained.
