Jan. 14 (UPI) -- The Taal Volcano in the Philippines showed hints of another large eruption Tuesday as it spewed thick layers of ash on the island nation.
The Philippine Institute of Volcanology and Seismology kept the volcano at the fourth level of its five-step alert, meaning another hazardous eruption is possible within hours or days. The Philippine Seismic Network recorded 49 volcanic earthquakes in the Taal region between 2 a.m. and 10 a.m. on Tuesday.
