Mayon (Luzon Island, Philippines): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20230630/1953Z VA CLD UNKNOWN REPORTED OBS VA DTG:30/1950Z
…30 Jun:
The effusive eruption at the volcano continues at heightened levels.
The actively growing lava dome in the inner summit crater continues to shed hot glowing rock falls by partial gravitational collapse of the dome. Such larger currents (four in particular) occurred at the volcano this evening between 18:09 and 20:00 local time by reaching a distance of approx. 3-4 km from the summit. Grey dense ash plumes separated from block-and-ash flows (so-called phoenix clouds) as they descended the southern Mi-si slope. The reason for these flows is the ongoing accumulation of viscous magma in the lava dome and its destabilization in the form of dome-block avalanches.

Karangetang (Siau Island, Sangihe Islands, Indonesia): (30 Jun) A new extrusive phase at the volcano started within the past hours, at best a few days ago.
Another batch of viscous magma started to rise into the southern summit Crater 1 lava dome, which has been oozing out of it, resulting in glowing dome-block avalanches. Block-and-ash flows have traveled over the south-southwestern slopes today, most of which reach the base of the dome area.
The Volcanic Ash Advisory Center (VAAC) Darwin reported ash emissions, which reached 8,000 ft (2,400 m) altitude and drifted SW.

…30 Jun:
The explosive eruption from the volcano persists.
Weak-to-moderate strombolian/vulcanian-sized explosions continue to take place from the summit vent at roughly regular intervals of 1 to 3 per hour. Eruptions released ash emissions to an elevation range between 4,500 m (14,800 ft). Ash plumes extended about 20 km to the west-southwest of the volcano. Ash fall is continually reported in the communities of Panimache I, Morelia and Santa Sofia.
