In its 5 a.m. bulletin, Phivolcs said that a fair crater glow or "banaag" can be seen around its summit. Entry into the 6-kilometer Permanent Danger Zone (PDZ) as well as flying any aircraft close to the volcano remains prohibited. Phivolcs also warned against possible rockfalls or landslides or avalanches; ballistic fragments; lava flows and lava fountaining; pyroclastic density currents as well as moderate-sized explosions. Mayon Volcano remains under Alert Level 3 but Director Teresito Bacolcol said on Friday, June 9 that they are not ruling out the possibility of raising Mayon Volcano’s alert level to 4. Meanwhile, Phivolcs also stated that a new summit lava dome in the Mayon Volcano Crater has emerged as its pre-existing one has been pushed out in increments that formed rockfall in the first week of June. "The Mayon Volcano Network has recorded a total of 59 rockfall events in the last 24-hour period and a total of 579 since 1 June 2023," it added.
