Sinabung (Sumatra, Indonesia): Explosions and generally small pyroclastic flows, sometimes happening together, continue to occur at the volcano at rates of a few per day on average.
Yesterday evening 17:55 local time, an explosion produced a plume that rose 2.3 km and a pyroclastic flow that traveled 1.5 km.

Dukono (Halmahera): Strong ash emissions continue to be reported from the volcano. Yesterday, a plume stretched almost 100 km to the NW.

Lokon-Empung (North Sulawesi, Indonesia): A warning was issued for the volcano and its alert level raised to 3 (“siaga” – alert, on a scale of 1-4) last Monday after a seismic swarm was detected to occur under the edifice.
The previous day (7 Mar), PVMBG recorded 25 deep and 138 shallow volcanic quakes, 23 rockfall signals as well as a tremor signal. In addition, deformation (inflation) was measured to occur under the Tompaluan crater.

While no to little changes were seen in surface activity (degassing), these geophysical parameters seem to suggest that internal pressure in the hydrothermal system of the volcano has recently increased and the risk of sudden explosions (phreatic or phreatomagmatic) has to be considered elevated at the moment.

Kilauea (Hawai’i): No significant changes in the ongoing eruption of Kilauea have occurred since the last update.
The lava lake at the summit caldera has dropped again and was about 33 m (108 ft) below the rim of the Overlook crater yesterday.
On the eastern rift zone, the recently active lava flows inside Puʻu ʻŌʻō crater were now inactive. Lava originating from the vent continues to flow into tubes, feeding scattered surface lava flows on the slowly growing “June 27th” lava field. All active breakouts remain within 6-7 km distance and far from any nearby communities.

Santiaguito (Guatemala): Activity at the Caliente lava dome continues to be high. Another moderately strong explosion occurred yesterday morning, causing a part of the Caliente lava dome to collapse and form pyroclastic flows on its north-northeastern flank.
According to a bulletin of the INSIVUMEH volcano observatory, an ash column rose to 4,000 m altitude and produced light ash fall in areas to the NNE including Quetzaltenango and Santa Marcos Palajunoj.

Tungurahua (Ecuador): The activity remains very elevated at the volcano. During yesterday and the night, several more explosions occurred ejecting incandescent material that produced glowing avalanches of up to 1500 length mainly on the western and northwestern flanks.
The ash plume continues to reach up to 30-32,000 ft (9-10 km) altitude and drifts SSE, Washington VAAC reports.
