Kliuchevskoi (Kamchatka): (18 Mar) Mild activity is again occurring at the summit vent of the tall stratovolcano. Aviation color code is orange.
KVERT reports that the "moderate explosive eruption of the volcano continues: gas-steam plumes containing small amount of ash are observing. Satellite data showed: ash plumes rose up to 5 km a.s.l. and drifted about 90 km to the north-east and east of the volcano; a weak thermal anomaly was noted over the volcano."

Zhupanovsky (Kamchatka, Russia): Tokyo VAAC reports an eruption this morning that produced an ash plume at approx. 23,000 ft (7 km) altitude and extending NE.

Sakurajima (Kyushu, Japan): (18 Mar) The volcano remains in a very active phase with 5-10 daily explosions. An eruption on 16 March produced an ash plume to 14,000 ft (4.2 km) altitude, i.e. rising approx. 3 km above the Showa crater.

Raung (East Java): (18 Mar) Strombolian activity continues from the vents inside the summit caldera of the volcano. Raung's alert level of the volcano was raised to 2 (on a scale of 1-4) a week ago.
An increasing number of volcanic-tectonic earthquakes had been detected. These quakes are indicators of rock breaking at depth, which can be caused by pressurized fluids, such as magma, intruding into the system.

Villarrica (Central Chile): (18 Mar) Activity at the volcano is again increasing, which could again culminate in another paroxysm. Since 14 March, degassing and seismic activity have been observed to rise. Phases of mild strombolian activity appeared again on 16 March.
SERNAGEOMIN described projections of incandescent material to up to 150 m. ONEMI and SERNAGEOMIN maintain alert level yellow (which might be raised in the case the activity further increases). A 3 km exclusion zone is in place around the summit.
