There is no lava on the surface of Kilauea volcano. Since the last, brief eruptive episode due to an intrusion in the upper eastern rift zone on 18/19 June, Pu'u O'o, the vent of the recent long-lasting eruption, is slowly deflating while HVO records continuing inflation at the summit caldera.

Based on observations from satellite imagery and Significant Meteorological Information (SIGMET) advisories, the Buenos Aires VAAC reported that during 13-17 June continuous emissions from Ubinas produced ash plumes to altitudes of 5.8-6.7 km (19,000-22,000 ft) a.s.l. Plumes drifted NNE, E, SE, SW, and W.
Data from deformation-monitoring instruments indicated that during 13-19 June lava-dome growth at Mount St. Helens continued. Seismicity persisted at lowlevels, punctuated by M 1.5-2.5, and occasionally larger, earthquakes. In some instances, clouds inhibited visual observations.
MVO reported that during 8-18 June the lava dome at Soufrière Hills changed very little based on visual observations, and seismic activity was very low. Low-level rockfall and pyroclastic flow activity continued. The Alert Levelremained at 4 (on a scale of 0-5).
KVERT reported that seismic activity at Shiveluch continued above background levels during 8-15 June and a thermal anomaly in the crater was detected on satellite imagery. Gas-and-steam plumes rose to altitudes of 4 km (13,100 ft) a.s.l. during 8-10 and 13 June. Ash plumes rose to altitudes of 4.5 km (14,800ft) a.s.l. on 8 and 10 June and were seen on satellite imagery drifting NW on 12 June. Based on seismic interpretation, multiple ash plumes rose to 6.3 km (20,700 ft) a.s.l. during 8-15. The Level of Concern Color Code remained at Orange.
Based on information from JMA, the Tokyo VAAC reported an explosion from Sakura-jima on 16 June. Ash was not detected on satellite imagery.

Based on seismic interpretation, IG reported that lahars occurred on the flanks of Reventador on 15 and 19 June. According to the Washington VAAC, the IG reported that activity on 18 June possibly produced ash plumes that drifted NW. Ash was not visible on satellite imagery.
RVO reported that during 19-20 June, four explosions from Rabaul caldera's Tavurvur cone produced shockwaves that rattled windows of houses in Rabaul Townand surrounding areas. The explosions showered the flanks of the volcano with lava fragments. Ash plumes rose to an altitude of 2.7 km (8,900 ft) a.s.l. and drifted NW. Ashfall was reported from Rabaul Town and surrounding areas.
The Washington VAAC reported that a plume from Masaya composed of little to no ash was visible on satellite imagery on 12 June.
Seismic activity at Karymsky indicated that ash plumes rose to an altitude of 6.8 km a.s.l. during 8-13 June. The Level of Concern Color Code remained at Orange.

Santiaguito lava dome is showing an above average level of activity. Explosions from the lava dome produce ash plumes rising to altitudes of 4.3-4.7 km (14,000-15,400 ft) a.s.l., that drift mainly to the SW.
Kliuchevskoi continues to be active above background levels. Video and visual observations during 1-4 June show strombolian and vulcanian eruptions at the summit crater, as well as lava flows generating steam explosions where hot lava interacts with ice on the NW and SE flanks. Ash plumes rose to altitudes of 7 km (23,000 ft) a.s.l. and drifted E and SE during 1-6 June. Plumes were seen on satellite imagery drifting E and S during 1-8 June. Based on information from KVERT, the Tokyo VAAC reported that an ash plume rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted NW on 12 June....mehr
During the past week, activity at Karymsky volcano had been decreasing, although sprodic strombolian ash explosions are still occurring. After a temporary decrease from Orange to Yellow, KVERT raised the alert level back to Orange, following an explosion on 9 June....mehr

Based on observations from satellite imagery and Significant Meteorological Information (SIGMET) advisories, the Buenos Aires VAAC reported that during 30 May-3 June and on 6 June ash plumes from Ubinas rose to altitudes of 3.7-7.6 km (12,000-25,000 ft) a.s.l. Plumes drifted NE, ESE, and SSE.
During 30 May-5 June, IG reported that ash plumes intermittently visible from Tungurahua rose to altitudes of 6-7 km (19,700-23,000 ft) a.s.l. and drifted mainly SW, W, and NW. Ashfall was reported from areas down wind between 30 Mayand 3 June. Muddy waters traveled down W, SW, and NW drainages during 30 May-1 June. Lahars were reported from the Choglontus drainage to the WSW on 30 May and from the Motilones drainage to the WNW on 1 June. During 4-5 June, roaring noises were reported.
Data from deformation-monitoring instruments indicated that during 23-29 Maylava-dome growth at Mount St. Helens continued. Seismicity persisted at low levels, punctuated by M 1.5-2.5, and occasionally larger, earthquakes. In general, gas and steam plumes from the active lava dome, as well as dust plumes resulting from rockfalls, occasionally rise above the crater rim; a gas plume may have been visible on 3 June. In some instances, clouds inhibited visual observations.
MVO reported that during 25 May-1 June the lava dome at Soufrière Hills changed very little based on visual observations and seismic activity was very low. Low-level rockfall and pyroclastic flow activity continued. On 31 May, pyroclastic flows traveled approximately 1 km E in the Tar River Valley. The Alert Level remained at 4 (on a scale of 0-5).
KVERT reported that seismic activity at Shiveluch continued above background levels during 25 May-1 June.
Based on information from JMA, the Tokyo VAAC reported that ash plumes from Sakura-jima rose straight up to altitudes of 2.1-2.4 km (7,000-8,000 ft) a.s.l. during 31 May-1 June. During 4-5 June, plumes again rose to the same altitudes as during 31 May-1 June and drifted W, NW, and E. Ash was not detected onsatellite imagery.
INSIVUMEH reported that on 31 May, and 1 and 5 June, lava from the NE flank of Pacaya's Mac Kenney Cone continued to flow and pooled between the base of the volcano and the plateau. Gas plumes from the summit drifted N and SW and rose to altitudes of 2.8 km (9,200 ft) a.s.l. on 5 June. Small pyroclastic explosions from the N part of Mac Kenney Cone were occasionally observed.
