Ash from Mayon Volcano in the Philippines erupts over the weekend, with large ash clouds reported over Luzon island. Multiple outlets report that the eruption sends thick plumes into the sky and leads to ashfall reaching nearby towns and communities. Philippine officials issue alerts for areas around the volcano, and more than 5,400 people flee to emergency shelters. One report also says roughly 200,000 people across dozens of villages are affected by ash and related conditions, including reduced visibility. Several sources add detail on the event’s nature: there is no explosive eruption reported from Mayon at the time described, and the ash is linked to the collapse of lava deposits on the volcano’s slopes. One account describes lava deposits on the southwestern slope cascading down in a pyroclastic flow prior to nightfall on Saturday, producing hot rocks, ash and gas. Media also includes video footage showing ash darkening skies and prompting rapid movement by residents, including people outdoors near Legazpi City.
