LEGAZPI, Philippines—The Philippines’ most active volcano was gently spewing lava down its slopes Monday, alerting tens of thousands of people they may have to quickly flee a violent and life-threatening explosion.
More than 12,600 people have left the mostly poor farming communities within a 6-kilometer (3.7-mile) radius of Mayon Volcano’s crater in mandatory evacuations since volcanic activity increased last week. But thousands more remain within the permanent danger zone below Mayon, an area long declared off-limits to people but where generations have lived and farmed because they have nowhere else to go.
