Etna (Sicily, Italy): Another lava-fountaining episode (paroxysm) occurred this morning at the volcano.
Visibility of the new eruptive phase was very limited due to dense clouds, but some observers could catch glimpses of the lava fountain and ash column that rose several kilometers. It appears that the new paroxysm was shorter but stronger than the previous paroxysm on 13-14 Dec.

Klyuchevskoy (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 25000 ft (7600 m) altitude or flight level 250 and is moving at 15 kts in SE direction.
The full report is as follows: VA EMISSIONS CONTINUING OBS VA DTG:21/1720Z to 25000 ft (7600 m)

Sakurajima (Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: VA IS NOT IDENTIFIABLE IN SATELLITE IMAGERY.

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ACTIVITY CONT. VA AT 20201221/1800Z OVER FL040 EXTD

Kilauea (Hawai'i): Shortly after the eruption began, lava erupted form the new fissures inside the summit crater came in direct contact with the existing water lake. The result was a very explosive interaction that evaporated the lake completely, now being replaced by a pond of lava.
The Hawai'i Volcanoes National Park posted a spectacular image showing this activity. The explosions between lava and water not only generated massive amounts of steam, but also fragmented lots of rock and lava material, generating a tall steam and ash plume that rose to approx. 9000 m initially. By now, this activity has died out as most available water disappeared.
...21 Dec:
The volcano observatory posted a vertical image with the approximate location of the new vents, 3 in total, on the lower NW walls of the Halema'uma'u pit crater.
In the attached image, "the red spots are the approximate locations of fissure vents feeding lava flowing into the bottom of Halema‘uma‘u crater.

...21 Dec:
As dawn breaks over Kilauea volcano, some details about the new eruption can be seen: the new vents are eruptive fissures in the western and northwestern lower walls of the pit crater. They produce low lava fountains that feed flows that have been creating a pool of lava at the bottom of the crater.
The former water lake seems to have disappeared completely. Likely, scientists from the volcano observatory will report a more detailed update in the coming hours.
...21 Dec:
USGS posted the following summary with interesting information about the activity at the volcano during the weeks preceding today's new eruption:
"For the past several weeks, the USGS Hawaiian Volcano Observatory (HVO) has recorded ground deformation and earthquake rates at Kīlauea Volcano's summit and upper East Rift Zone that have exceeded background levels observed since the conclusion of the 2018 lower East Rift Zone eruption and summit collapse.

...21 Dec:
Livecam imagery shows what seems to be lava fountaining from vents at the bottom of the Halema'uma'u pit crater, where the water lake had been until yesterday.
...21 Dec:
The eruption which has started about 2 hours ago inside the summit caldera is now producing a strong glow from the Haleama'uma'u crater.
The exact location of the new vents is not clear yet. The most likely candidate is the deep pit crater which had contained the lava lake until the eruption in 2018 and was refilled with a slowly growing hot water lake. The presence of water is likely causing significant explosive interaction (phreatomagmatic activity) of water and magma.
...21 Dec:
A new eruption started at Kilauea volcano in the evening of 20 Dec in Hawaii (local time). The volcano observatory reported:
"Shortly after approximately 9:30 p.m. HST, the USGS Hawaiian Volcano Observatory (HVO) detected glow within Halemaʻumaʻu crater at the summit of Kīlauea Volcano. An eruption has commenced within Kīlauea's summit caldera. The situation is rapidly evolving and HVO will issue another statement when more information is available."
