Tungurahua, Ecuador

During 25-27 and 30-31 March, IG reported that steam-and-ash plumes from Tungurahua rose to altitudes of 5.5-7 km (18,000-23,000 ft) a.s.l. and drifted NW, NE, E, and SW. On 25 March, ashfall was reported in areas to the SW and lahars traveled down a drainage to the W. On 26 March, lahars traveled down multiple [...]

Suwanose-Jima, Ryukyu Islands, Japan

Based on information from JMA, the Tokyo VAAC reported an explosion from Suwanose-jima on 28 March. JMA reported three explosions on 30 March. Details of possible resultant ash plumes on either day were not reported.

Shiveluch, Russia

KVERT reported that seismic activity at Shiveluch was above background levels during 20-27 March. Based on interpretations of seismic data, ash plumes likely rose to an altitude of 6 km (19,700 ft) a.s.l. According to observers, fumaroles were active during 23-26 March and explosions produced ash plumes that rose to an altitude of 8 km [...]

Sakura-Jima, Japan

Based on information from JMA, the Tokyo VAAC reported that an explosion from Sakura-jima on 26 March produced a plume that rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted SE. JMA reported occasional weak eruptions during 27-30 March.

Koryaksky, Kamchatka Peninsula, Russia

KVERT reported that seismic activity at Koryaksky was at background levels during 20-27 March. Gas plumes containing a small amount of ash rose to an altitude of 4 km (13,200 ft) a.s.l. and drifted S, SE, W and NW during the reporting period. On 25 and 26 March, gas-and-ash plumes were also seen on satellite [...]

Kilauea, Hawaii, USA

During 24-31 March, HVO reported that lava flowed SE from underneath Kilauea’s Thanksgiving Eve Breakout (TEB) and rootless shield complex through a lava tube system, reaching the Waikupanaha and Kupapa’u ocean entries. Daily thermal anomalies seen on satellite imagery suggested surface flows on the coastal plain.
The vent in Halema’uma’u crater continued to produce a predominantly [...]

Karymsky, Russia

KVERT reported that seismic activity at Karymsky was elevated during 19-22 March and at background levels during 23-24 March. Based on interpretations of seismic data, ash plumes likely rose to an altitude of 2 km (6,600 ft) a.s.l. On 26 March, ash deposits extending 30 km S of the volcano were seen on satellite imagery. [...]

Fuego, Guatemala

On 27 and 30 March, INSIVUMEH reported that explosions from Fuego produced ash plumes that rose to altitudes of 4.1-4.8 km (13,500-15,700 ft) a.s.l. and drifted S and SW. Some explosions were accompanied by rumbling noises, shock waves detected 10 km away, and avalanches of blocks down the W and SW flanks. Fumarolic plumes drifted [...]
