Etna (Sicily, Italy): A brief, but intense episode of explosive activity took place at Etna's SE crater this morning. Starting in the early morning hours, from around 07:30 local time, the New Southeast Crater began to produce strombolian-type explosions along with a sharp increase in volcanic tremor.
Activity rapidly increased in intensity, producing a weak lava fountain and an ash column that rose approx. 1 km. Incandescent lava covered most of the New SE crater, but no lava flow was produced.

Klyuchevskoy (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 22000 ft (6700 m) altitude or flight level 220 and is moving at 20 kts in SE direction.

The full report is as follows: VA EMISSIONS CONTINUING OBS VA DTG:19/1720Z to 22000 ft (6700 m)
...19 Apr:
After increased activity of the volcano during the past weeks associated with strong strombolian-vulcanian type explosions, the lava flow has started to descend on the southeastern flank.
Ash emissions reached 16,400-23,000 ft (5,000-7,000 m) altitude. The plumes were dispersed towards the northeast direction.

Aso (central Kyushu, Japan): (19 Apr) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ACTIVITY CONT. VA AT 20200419/0000Z FL070 EXTD NE OBS VA DTG:18/2350Z

Mayon (Luzon Island, Philippines): (19 Apr) Mayon Volcano's seismic monitoring network recorded 3 rockfall related events over the past 24-hours. Steam plume emissions drifted west and west-northwest. Faint crater glow from the summit could be observed at night. Sulfur dioxide (SO2) emissions was measured at an average of 176 tonnes/day on 17 April 2020. Inflation of the middle to upper portions of the volcanic edifice that began in the last quarter of 2019 continues.

"DOST-PHIVOLCS reiterates that Alert Level 2 currently prevails over Mayon because the volcano is at a moderate level of unrest."

"It is therefore strongly recommended that entry into the six kilometer-radius Permanent Danger Zone or PDZ and a precautionary seven kilometer-radius Extended Danger Zone or EDZ in the south-southwest to east-northeast sector, stretching from Anoling, Camalig to Sta. Misericordia, Sto. Domingo should be strictly prohibited. The public is reminded that sudden explosions, lava collapse, pyroclastic density currents or PDCs and ashfall can occur without warning and threaten areas in the upper to middle slopes of Mayon. People residing close to these danger areas are also advised to observe precautions against rockfalls, PDCs, and ashfall. Active stream/river channels and those identified as perennially lahar-prone areas on all sectors of the volcano should also be avoided especially during extreme weather conditions when there is heavy and prolonged rainfall. Civil aviation authorities must advise pilots to avoid flying close to the volcano's summit as airborne ash and ballistic fragments from sudden explosions and PDCs may pose hazards to aircraft."

Semeru (East Java, Indonesia): (18 Apr) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA REPORTED TO FL120 AT 18/2230 OBS VA DTG:18/2330Z

Dukono (Halmahera): (19 Apr) 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 .
The full report is as follows: CONTINUOUS VA EMISSION TO FL070 MOV NW OBS VA DTG:19/0500Z to 7000 ft (2100 m)

White Island (New Zealand): (19 Apr) The volcano continues to emit SO2 gas, which is derived from magma at shallow depth beneath the surface and is one of the main indicators of volcanic unrest. Since the last update, there have been no significant changes in SO2 output. Emission rates for other gases were not measured due the lockdown from COVID-19. Seismic activity remains at lower levels and continues to fluctuate over periods of hours or days.
GEONET report that the layout of the active vent areas appears to be mostly unchanged since early March and that there is evidence of high temperatures at night, but no changes in the locations of these heat sources are apparent.
