Explosion from Fuego yesterday (INSIVUMEH)
: Explosions have become more violent, the latest special bulletin of INSIVUMEH indicates. Mild strombolian eruptions have turned into more powerful vulcanian-type explosions, which eject dense ash plumes rising to 800 m and produce numerous avalanches of blocks around the crater, especially on the southern flank.

Weak ash emissions occurred on Wednesday (26 June). Seismic activity otherwise has remained at low levels.
MODIS hot spot data for Veniaminof volcano showing the area of fresh lava flows (ModVolc, Univ. Hawaii)
Volcanic tremor and small explosions continue to be detected in seismic data indicating that the eruption of lava and minor amounts of ash and steam continues.
ven., 28 juin 2013, 15:06
Eruptive activity is continuing, but at a much lower level than earlier this week. The level of seismicity over the past 24 hours has continued to decline and now consists primarily of low level continuous tremor. Periods of continuous tremor are likely associated with lava fountaining and minor ash production, but at this level, emission rates are probably very low.

SO2 plume from Ambrym volcano (NOAA)
The lava lakes in Benbow and Ambrym craters have been very active during the recent weeks. A large SO2 plume is visible today on NOAA satellite data.

Except for a small swarm of earthquakes on 20 June, Etna continues to be calm.
ven., 28 juin 2013, 14:43The volcano continues to emit a strong steam and ash plume visible on satellite images. This activity has been typical of Pagan in the recent months, but no ash emissions could be detected.

Shiveluch (Kamchatka): A phase of intense activity occurred last night starting at 19:10 UTC, and lasting for about 40 minutes. The activity was probably a major collapse of the dome and/or accompanied by explosions. It produced a large ash plume rising to about 10-12 km altitude (VAAC Tokyo) into the atmosphere. Due to cloud cover, no direct observations could be made.

Activity has not changed much overall, but the viscous lava flow on the south side of the dome has become more active and now produces frequent avalanches. INSIVUMEH warns that these can now sometimes turn into pyroclastic flows.

jeu., 27 juin 2013, 16:21Explosions have become more frequent and stronger. Dense ash plumes rose up to 600 m above the crater. Shock waves from the explosions made windows and roof vibrate in houses of Sangre de Cristo, Panimache, Morelia and others in the area. (INSIVUMEH)

Mild, typical strombolian activity has established itself inside the Mackenney crater. "Dry" (not containing much ash) explosions occur frequently and eject incandescent scoria to about 25 m height above the crater and an intra-crater cone, now about 15 m high, is being formed inside the crater. Some of the explosions can be heard in up to 5 km distance. At night, glow can be seen from the crater.

Seismic activity has picked up, suggesting that the volcano could be headed for more vigorous activity soon. SO2 emissions on NOAA recent satellite data have been relatively high as well.

Effusive and weak explosive activity continue. Volcanic tremor and small explosions continue to be detected in seismic data and satellite data continue to show elevated surface temperatures at the intracaldera cone. A light colored plume is rising above the cone to just above the rim of the caldera to about 8,000 to 10,000 feet above sea level and at night, a persistent glow is visible. (AVO)
jeu., 27 juin 2013, 15:56The eruption had increased yesterday and produced ash plumes rising up to about 8.5 km (28,000 ft), but has decreased in strength again today.

Our group on the rim of Anak Krakatau's crater
The group of our current trekking tour on Java climbed the summit of Anak Krakatau on 24 June. Climbing there was very difficult, because of many hot fumarolic spots and strong degassing. The summit of Anak Krakatau is now higher than before the Sep 2012 eruption. One active vent was remaining in the west part.
mer., 26 juin 2013, 06:00KVERT reported that the S fissure along the W side of Tolbachinsky Dol, a lava plateau on the SW side of Tolbachik, continued to produce very fluid lava flows during 21-28 June that traveled to the W, S, and E sides of the plateau. Cinder cones continued to grow along the S fissure and weak gas-and-steam plumes were observed. A large thermal anomaly on the N part of Tolbachinsky Dol was visible daily in satellite imagery.

During 26 June-2 July, INSIVUMEH reported that ash plumes frequently rose from Santa María's Santiaguito lava-dome complex. Explosions during 26-28 June generated ash plumes that rose at most 900 m and drifted SW; ashfall was reported in Monte Claro (S) and Finca La Florida (5 km S) during 27-28 June. Avalanches originated from the lava flow on the S flank and from the SW lava dome, and produced pyroclastic flows on 27 June.

Strombolian activity was observed from MacKenney cone the following day; weak-to-moderate explosions ejected small amounts of tephra 8 m above the crater that were then deposited on the W flank. Audible explosions were noted up to 5 km away.

KVERT reported that during 21-28 June moderate seismic activity continued at Kizimen. Video and satellite data showed that lava continued to extrude from the summit, producing incandescence, strong gas-and-steam activity, and hot avalanches on the W and E flanks. A thermal anomaly was detected in satellite images during 21-23 June; cloud cover prevented views of the volcano on the other days.

The plume from the vent continued to deposit variable amounts of ash, spatter, and Pele's hair onto nearby areas.
