During 26 June-2 July, volcanism at Tungurahua consisted of small emissions of gas, steam, and ash. For several days, frequent explosions emitted rocks and incandescent material that traveled down the volcano's flanks. IG reported that an explosion on 1 July at 1123 produced an ash cloud that rose 1.5 km above the summit and drifted to the W. Read all- More about Tungurahua volcano

Volcanic and seismic activity were at low levels during 21-28 June at Soufrière Hills. Growth of the extruded lobe on the SE side of the lava dome appeared to have stagnated. The number of rockfalls decreased abruptly on the afternoon of 22 June, remained at low levels for the rest of the week, and declined to very low levels during the last 3 days of the report period.

Seismicity declined at Shiveluch during 21-28 June, but remained above background levels. It included earthquakes with magnitudes less than or equal to 1.9 at depths of 0-6 km, many local shallow seismic signals (from possible avalanches or weak gas-and-ash explosions), and episodes of weak intermittent volcanic tremor. Gas-and-steam plumes reached to 3 km above the lava dome and small avalanches were captured on video rolling down the dome on 23 June. Read all- More about Shiveluch volcano

During 26 June-1 July, there were small-to-moderate emissions of steam, gas, and ash at Popocatépetl. In addition, several episodes of low-amplitude harmonic tremor were recorded. The most notable emissions, on 26 June at 1110 and on 1 July at 0238, produced ash clouds to a height of ~2 km above the volcano. Read all- More about Popocatépetl volcano

During 21-28 June, seismicity was above background levels at Karymsky, with ~10 earthquakes occurring per hour. The character of seismicity suggested that weak ash-and-gas explosions and gas blow-outs had probably occurred. A steam-and-gas plume was visible on AVHRR satellite imagery on 25 June.

Volcanic activity at Soufrière Hills during 14-21 June was slightly higher than it had been the previous week. Rockfall activity increased abruptly on the night of 14 June and remained at moderately high levels until the 18th, when it declined. The active lobe on the SE side of the lava dome continued to grow and was topped by a small, low-angle spine extruded towards the SE. Read all- More about Soufriere Hills volcano

During 14-21 June, seismicity at Shiveluch remained above background levels and included earthquakes at depths of 0-6 km with magnitudes less than or equal to 2.4 on the 14th and less than or equal to 2 during the rest of the week. In addition, many local shallow seismic signals (from possible avalanches or weak gas-and-ash explosions) and episodes of weak intermittent volcanic tremor occurred. According to interpretations of seismic data, short-lived explosive eruptions on the 15th and 19th probably sent ash-and-gas plumes ~1 and 1.5 km above the lava dome, respectively.

Shallow seismic activity declined during 14-21 June at Kliuchevskoi, but 10-15 earthquakes ~30 km beneath the volcano occurred daily, and weak spasmodic tremor continued to be registered during the week. By the end of the week, shallow seismic events occurred again. Low-level gas-and-steam clouds rose above the volcano on several days. Read all- More about Klyuchevskoy volcano

Incandescent surface lava flows were sometimes visible at Kilauea during 19-24 June. Generally, seismicity was at background levels, except at Kilauea's crater where a swarm of long-period earthquakes that began on 5 June continued. In addition, moderate tremor occurred at Pu`u `O`o.

During 14-21 June, seismicity was above background levels at Karymsky, with ~10 earthquakes occurring per hour. The character of seismicity suggested that weak ash-and-gas explosions and gas blow-outs had probably occurred. Thermal anomalies were visible on satellite imagery, but ash was not.

During 17-23 June, ash continued to be emitted from Etna's Northeast Crater and to a lesser extent from Bocca Nuova crater. Ash plumes from Northeast Crater rose several hundred meters. Quiet degassing occurred at Voragine and Southeast craters. Seismicity was at low levels during the week. Read all- More about Etna volcano

During 13-17 June, continuous degassing occurred at Tungurahua, accompanied by nearly continuous volcanic tremor, long-period earthquakes, and occasional small-to-moderate explosions sometimes preceded by volcano-tectonic events. On 13 June incandescence was visible in the crater, volcanic blocks rolled 500-800 m down Tungurahua's flanks, and continuous ash emissions were followed by three small explosions. A pilot reported observing a W-drifting steam-and-ash column ~2 km above the volcano's summit. Read all- More about Tungurahua volcano

Volcanic and seismic activity remained at low levels at Soufrière Hills during 7-14 June. The massive extrusive lobe on the SE side of the lava dome continued to grow steadily throughout the week, although there was a low level of rockfall and seismic activity. Minor rockfall activity occurred on the E flank of the dome, increasing slightly during the latter half of the week. Read all- More about Soufriere Hills volcano

During 7-14 June, seismicity at Shiveluch remained above background levels and included earthquakes with magnitudes less than or equal to 2.3 at depths of 0-6 km, many local shallow seismic signals (from possible avalanches or weak gas-and-ash explosions), and episodes of weak intermittent volcanic tremor. According to interpretations of seismic data, from one to three short-lived explosive eruptions per day probably sent ash-and-gas plumes ~1 km above the lava dome.

During 12-18 June, activity at Popocatépetl mainly consisted of small steam-and-gas emissions. A photograph of the lava dome taken on 22 May revealed that it had diminished in size compared to 29 April. Based on information from ground reports, video footage, and MWO, the Washington VAAC reported that an eruption occurred on 17 June at 1140. Read all- More about Popocatépetl volcano
