A small but restive volcano south of the Philippine capital spewed a 1.5 km plume on Saturday, prompting authorities to raise an alert level and evacuate more than a thousand residents.
The alert for the Taal volcano, about 70 km (45 miles) south of central Manila, was increased to level 3 from level 2 on the 5-level scale, which the seismology and volcanology agency said meant "there is magmatic intrusion at the main crater that may further drive succeeding eruptions".
