REMARKS/RECOMMENDATION:

The status of Taal Volcano remains at Alert Level 1.  Significant volcanic and seismic events have been detected over the past months.  The Main Crater remains off-limits to the public because steam explosions may suddenly occur or high concentrations of toxic gases may accumulate.   Furthermore, the public is reminded that Taal Volcano Island is a high risk area and permanent danger zone, hence, habitation is strictly not recommended.
