Philippines Volcano: Manila raises volcano alert, warns of hazardous eruptions
[]
The Philippines has raised an alert at a restive volcano by one notch.
Officials worry rising magma that could indicate an eruption. Residents were evacuated from two nearby villages on Saturday. The Mayon volcano last erupted in 2014, spewing lava and forcing thousands of people to flee. Its most destructive eruption was in 1841 when lava flows buried a town and killed more than a thousand people.
