The new lava flow started to descend from the North Crater area early this morning. From about 05:20 local time, an increasingly larger dust could be seen traveling along the Sciara del Fuoco from the available INGV webcam, resulting gradually in small pyroclastic flows reaching the base of the slope. This was likely following as a result of a landslide and/or partial collapse of the crater rim area due to a magma surge leading to the new lava overflow.

...9 Mar:
Another short-lived lava flow erupted from the volcano yesterday, but already ended as of this morning.
It seems that a surge of magma arrived at the summit vents, causing the partial collapse of the northern crater rim, which in turn generated a small pyroclastic flow (hot avalanche of hot rocks and ash) that traveled down the Sciara del Fuoco and allowed the overflowing lava to form a flow descending towards the sea.
The event was similar to the lava flows observed during the past months at irregular intervals ranging between a few weeks to months. These have become more frequent recently. Activity at the volcano is currently classified as "high".
Shiveluch (Kamchatka): KVERT reported that the ongoing eruption at Sheveluch was generally characterized by explosions, hot avalanches, lava-dome extrusion, and strong fumarolic activity. A daily thermal anomaly was identified in satellite images during 23 February-2 March. At 1150 on 5 March local time video images showed an ash plume generated by hot avalanches rising 5.5 km a.s.l. (just over 2.2 km above the summit) and drifting 5 km NE.
The Aviation Color Code remained at Orange (the second highest level on a four-color scale). Dates are based on UTC times; specific events are in local time where noted.

Ebeko (Paramushir Island): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20230309/1940Z FL100 EXTD E REPORTED OBS VA DTG:09/2020Z
...9 Mar:
KVERT reported that moderate activity at Ebeko was ongoing during 23 February-2 March. According to volcanologists in Severo-Kurilsk (Paramushir Island, about 7 km E) explosions during 24 and 26-27 February and on 2 March generated ash plumes that rose as high as 4 km (13,100 ft) a.s.l. and drifted E.
Ashfall was reported in Severo-Kurilsk on 27 February. The Aviation Color Code remained at Orange (the second highest level on a four-color scale). Dates are based on UTC times; specific events are in local time where noted.

Sakurajima (Kyushu, Japan): JMA reported ongoing eruptive activity at Minamidake Crater and Showa Crater (at Aira Caldera's Sakurajima volcano) during 27 February-6 March. Incandescence was visible nightly at Minamidake and during 3-6 March at Showa. Explosions at Minamidake were recorded on 28 February and 1, 3, and 4 March, and non-explosive eruptive events were occasionally recorded.
Eruption plumes rose as high as 2.8 km above the Minamidake Crater rim and large blocks were ejected as far as 1.3 km from the vent. Non-explosive eruptive events were occasionally recorded at Showa during 27 February-2 March and four explosions occurred during 3-6 March. Eruption plumes rose as high as 2.7 km above the Showa rim and large blocks were ejected 500-800 m from the vent.

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20230309/1441Z FL060 STNR OBS VA DTG:09/1440Z
...9 Mar:
JMA reported that the number of explosions at Suwanosejima's Ontake Crater began to increase on 2 February and further increased on 2 March. Activity intensified and a total of 25 explosions were recorded during 1-5 March. Ash plumes rose as high as 1.4 km above the crater rim and large blocks were ejected as far as 500 m from the vent.
Crater incandescence was visible at night. Occasional ashfall and rumbling noises were reported in Toshima village (3.5 km SSW). Since large blocks could be ejected further than the restricted zone of 1 km, JMA raised the Alert Level to 3 (on a 5-level scale) at 0640 on 5 March and warned the public to stay 2 km away from the crater.

The explosive eruption of the volcano continues at roughly regular intervals of 2 to 3 per day.
According to the Volcanic Ash Advisory Center (VAAC) Tokyo, vulcanian-type explosions sent ash columns to approx. 2,5 km altitude on average over the past few days. The fine ash material extended to the north, south and southeast of the volcano. The JMA observatory reported that blocks were ejected 500 meters distance from the Ontake summit crater.

Dieng (Central Java): On 6 March PVMBG lowered the Alert Level for the Dieng Volcanic Complex to 1 (on a scale of 1-4) due to decreased carbon dioxide emissions. During the first half of January carbon dioxide emissions were elevated at Timbang Crater and then significantly increased in mid-January; recent measurements indicated a decreasing trend. On 22 February a mobile instrument measured 112,000 ppm CO2 at the crater, though the concentration dropped to 9,200 ppm at a distance of less than 10 m from the crater rim.
Measurements at the multi-gas station indicated concentration of 1,500-1,900 parts per million (ppm). The public was warned to stay 500 m away from Sileri Crater and to stay out of Timbang Crater, and to take caution when digging in the ground as gasses could be released from the soil.

Merapi (Central Java, Indonesia): BPPTKG reported that the eruption at Merapi (on Java) continued during 24 February-2 March and seismicity remained at high levels. The SW lava dome produced two lava avalanches that traveled as far as 1 km down the SW flank (upstream in the Bebeng and Boyong drainages). No significant morphological changes to the central and SW lava domes were evident in webcam images.
The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 3-7 km away from the summit based on location.

Semeru (East Java, Indonesia): PVMBG reported that the eruption at Semeru continued during 1-7 March. Weather clouds sometimes prevented views of the volcano, though on most days no emissions were visible. On 6 March white-and-gray ash plumes rose as high as 200 m above the summit and drifted N and NE.
The Alert Level remained at 3 (on a scale of 1-4). The public was warned to stay at least 5 km away from the summit in all directions, 13 km from the summit to the SE, 100 m away from the banks of the Kobokan drainage as far as 17 km from the summit, and to avoid other drainages originating on Semeru, including the Bang, Kembar, and Sat, due to lahar, avalanche, and pyroclastic flow hazards.

Papandayan (West Java): PVMBG issued a special report based on recent observations of Papandayan. The number of shallow volcanic earthquakes had increased in January and although the numbers fluctuated, low-frequency earthquakes also increased overall during January and February. Webcam images from the camera in the parking area showed incandescence emanating from Kawah Baru during the night on 22 February.
A team of PVMBG scientists inspected the crater during 2100-2300 on an unspecified date to identify the source of the incandescence. They observed intense emissions rising from Kawah Baru, heard faint rumbling, and detected a strong sulfur odor, but did not see incandescence. Gas plumes rose 300 m from a solfatara.

The explosive eruption at the volcano continues at roughly regular intervals.
Surveillance cameras of San Salvador's Ministerio de Medio Ambiente are being observed ash eruptions from the summit crater. The heights of grey ash plumes are unknown as they weren't reported by the VAAC nor the volcano observatory, but from the attached video from 8 March, they seem to rise several hundred meters above the vent.
