The Mayon volcano spews ash as the sun sets behind Legazpi city on Jan. 25, 2018 in Albay province, Philippines.

Mount Mayon has been acting up for more than a week, ejecting ash and lava fountains up to 1.8 miles from the crater in a picturesque but increasingly dangerous eruption. There have been no reports of injuries and law enforcers have struggled to keep villagers and tourists from sneaking into danger zones.
