The 8th paroxysm in 2011 from the new SE crater of Etna occurred in the evening of 30 July 2011. Spectacular continuous lava fountains rose to more than 500 m between 9.30pm and 11pm. The paroxysm followed a gradual build-up of strombolian activity during the previous days. Large lava flows forming a broad sheet descended into the Valle del Bove and reached more than 2 km length.. - More about Etna volcano

AVO reported that on 2 August the Volcano Alert Level for Cleveland was raised to Watch and the Aviation Color Code was raised to Orange due to the formation of a 40-m-wide lava dome in the summit crater that was observed on 29 July. The lava dome was extruded sometime after 7 July following the last clear view of the summit area, however thermal anomalies observed since 19 July suggested that the dome had extruded since that time.

Sezione di Catania - Osservatorio Etneo reported that in the evening of 28 July Strombolian explosions from the active vent on the E flank of Etna's SE Crater cone were weak and sporadic, then ceased during the night. Throughout 29 July the crater was quiet. In the early morning of 30 July intermittent incandescence from the crater gradually intensified and became more frequent, then was followed by intense Strombolian activity accompanied by loud detonations.

CVGHM reported increased seismicity from Marapi during 21 June-3 August. Observers noted that during June and July white plumes rose 15-75 m above the summit craters. On 1 August white plumes rose 15 m above the main crater; fog prevented observations the next day. Read all- More about Marapi volcano

OVSICORI-UNA reported that on 23 July a group of observatory scientists visited Poás to document changes that had occurred there during the previous weeks. They noted that the subtle, semicircular scarp observed a few months earlier had rapidly progressed to a sharp scarp on the SE shore of Laguna Caliente. The 60-m-wide, 2.5-m-high scarp degassed and geyser activity was observed on the W end, next to the steaming lake. Read all- More about Poas volcano

RVO reported that white vapor occasionally tinted blue rose from Rabaul caldera's Tavurvur cone during 1-28 July. Dull incandescence emanated from a small caved-in vent on the floor of the crater. The start of an ash eruption on 29 July was marked by an emergent low-frequency tremor and slowly rising gray ash plumes. Read all- More about Rabaul (Tavurvur) volcano

Sezione di Catania - Osservatorio Etneo reported that during the late evening of 1 August a vast accumulation of incandescent material appeared at the base of Stromboli's N1 vent, the northernmost active vent within the crater terrace at about 750 m elevation. Within a few minutes, the material collapsed and slid downslope, creating two small lobes of lava. The more easterly flow descended the N slope of the Sciara del Fuoco, generating small landslides from the loose material on the slope, and marking the first lava effusion event outside of the crater since a small emission during 11-12 December 2010.

Based on information from JMA, the Tokyo VAAC reported that during 27 July-2 August plumes from Sakura-jima rose to altitudes of 1.8-3 km (6,000-10,000 ft) a.s.l. During 28-30 July and 1 August, pilots observed ash plumes that rose to altitudes of 2.1-3 km (7,000-10,000 ft) a.s.l. Plumes occasionally drifted SW, S, SE, and W.

KVERT reported that during 22-29 July moderate seismic activity continued at Karymsky and possible ash plumes rose from the crater. A thermal anomaly on the volcano was detected by satellite during 22 and 24-27 July; cloud cover prevented observations on the other days. The Aviation Color Code remained at Orange.

HVO reported that two lava lakes at Kilauea were active during 27 July-2 August. The level of the summit lava lake fluctuated deep in the 150-m-diameter vent inset within the E wall of Halema'uma'u Crater and circulated with various patterns. Periodic measurements indicated that the gas plume from the vent continued to deposit variable amounts of ash and occasionally fresh spatter nearby. Read all- More about Kilauea volcano

KVERT reported that photos taken of Kizimen on 20 July showed that the lava flow on the E flank, which began in January, remained active. During 22-29 July seismicity was above background levels and weak volcanic tremor continued to be detected. Satellite images showed a bright thermal anomaly on the volcano all week and seismic data indicated that possible ash plumes rose to an altitude of 3 km (10,000 ft) a.s.l.

During 25 July-1 August, OVDAS-SERNAGEOMIN reported that the eruption from the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, continued and seismicity indicated that the lava flow remained active. Cloud cover prevented observations by a video camera on 25 July, though satellite imagery detected a plume that drifted 200 km SE. On 26 July the camera recorded a plume that rose 2 km above the crater and incandescence up to 500 m above the crater was observed at night. Read all- More about Puyehue-Cordón Caulle volcano

KVERT reported that seismic activity at Shiveluch was moderate during 22-29 July and indicated that possible ash plumes rose to an altitude of 4.7 km (15,400 ft) a.s.l. during 23 and 25-27 July. Satellite imagery showed a thermal anomaly on the lava dome on 22 July; cloud cover prevented observations on other days. Read all- More about Shiveluch volcano

Kīlauea volcano continues to pressurize with new magma, uplifting the floor of Pu`u `O`o crater on the order of 1 meter / 3 feet PER DAY over the last month! This uplift has allowed lava flows to emit from the base of the inner crater walls, filling the neighboring craters (MLK & Puka Nui) to overflowing to the southwest starting last night! The inner crater lava flows show up via webcam (check our link below), with visible cracking occuring as the whole crater floor is pistoned upwards! Read all- More about Kilauea volcano

Another powerful paroxysm occurred early today at Etna volcano from the new SE crater, making this episode Nr 7 of this kind in 2011, almost exactly 6 days after the last eruption on 19 July. It seems that the intervals between single paroxysms are becoming shorter. - More about Etna volcano

Based on analysis of data collected by the Vanuatu Meteorology and Geohazards Department (VMGD), the Vanuatu Geohazards Observatory reported that a small series of explosions from Aoba occurred on 10 July. Photos showed that the volcano was quiet on 12 July, although ongoing earthquakes were detected. On 18 July the Vanuatu Volcano Alert Level (VVAL) remained at 1 (on a scale of 0-4).

AVO reported that on 20 July the Volcano Alert Level for Cleveland was raised to Advisory, and the Aviation Color Code was raised to Yellow, due to thermal anomalies visible in satellite imagery during 19-20 and 22 July. Cloud cover prevented observations during 21 and 23-26 July. No current seismic information was available because Cleveland does not have a real-time seismic network.

Sezione di Catania - Osservatorio Etneo reported that the seventh eruption of Etna in 2011 occurred from the active crater on the E flank of the SE Crater cone. On 24 July vigorous Strombolian activity started within the crater, gradually increased through the night, and culminated on 25 July. Strombolian activity gradually turned into a pulsating lava fountain, accompanied by increasingly voluminous ash emissions. Read all- More about Etna volcano

CVGHM reported that during 20-21 July seismicity and visual observations of Tompaluan crater, in the saddle between the Lokon-Empung peaks, indicated that activity continued to be high. On 20 July plumes rose 100-500 m above the crater, and during 21-24 July white plumes rose 100-300 m above the crater. CVGHM noted that, since the eruption on 18 July, most data showed a decline in activity and therefore on 24 July the Alert Level was lowered to 3 (on a scale of 1-4).

CVGHM reported that on 3 July an explosion of incandescent material from Soputan was followed by a 6-km-high ash plume and a pyroclastic flow that traveled as far as 4 km W. Later that day a dense white plume rose 50 m above the crater. On 20 July CVGHM noted that since 4 July seismicity had decreased and only diffuse white plumes rose 75 m above the crater until 18 July. Read all- More about Soputan volcano
