Volcanic activity worldwide 27 Jun 2019: Klyuchevskoy volcano, Popocatépetl, Shiveluch, Dukono, Rev...

Klyuchevskoy (Kamchatka): (27 Jun) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: VA IS NOT IDENTIFIABLE IN SATELLITE IMAGERY.

Shiveluch (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 and is moving at 15 kts in SW direction.
The full report is as follows: VA EMISSIONS CONTINUING OBS VA DTG:27/1720Z to 14000 ft (4300 m)

Ebeko (Paramushir Island): (26 Jun) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20190626/2116Z FL110 EXTD NE REPORTED OBS VA DTG:26/2130Z

Raikoke (Central Kuriles): (27 Jun) The activity at the small island volcano itself seems to have decreased a lot or even ceased - there are no more new ash alerts issued that mention new emissions at the volcano itself, and no significant heat signals can be found.

However, VAAC Anchorage continues to alert about the possible remaining ash clouds from the main phase of the eruption during 21-22 June. On the other hand, most of this ash must by now have been dispersed sufficiently to fall below direct detection by satellite-based sensors.
What is still clearly being detected is the significant SO2 gas plume: in various branches, it hovers over parts of Siberia, the northern Pacific and Alaska mainly at altitudes between 9-13 km.

Ulawun (New Britain, Papua New Guinea): (27 Jun) The activity at the volcano seems to have decreased a lot or ceased last evening at the end of the very violent eruptive phase.
Satellite observations show that the impressive umbrella cloud topping out and spreading as a circle more than 150 km diameter in the lower stratosphere rather quickly dissipated when the eruption column stopped feeding it.

VAAC Darwin has still a warning in place of ash plumes at up to 55,000 and 45,000 ft altitude (flight levels 550 and 450) as the attached picture shows, but expects the ash to dissipate during the next 12 hours or so.


Sangeang Api (Indonesia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 .

Dukono (Halmahera): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 and is moving at 5 kts in NE direction.
The full report is as follows: CONTINUOUS VA TO FL070 EXT NE OBS VA DTG:27/2020Z to 7000 ft (2100 m)
