Here is a summary of the new activity and unrest of the volcanoes around the Earth from
The Weekly Volcanic Activity Report from the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program.
GAUA Banks Islands (SW Pacific) 14.27°S, 167.50°E; summit elev. 797 m
Vanuatu Geohazards Observatory reported that the seismic network monitoring Gaua detected volcanic activity in August. Gas plumes were detected by the OMI satellite on 17, 27, and 28 September, and ashfall was reported in the N, E, and W parts of Gaua on 10 October by local authorities. The Alert Level remained at 1 (on a scale of 0-4).
KRAKATAU Indonesia 6.102°S, 105.423°E; summit elev. 813 m
On 8 October, a news article stated that activity at Anak Krakatau was increasing; the number of seismic events was 5,204 on 6 October, 5,543 on 7 October, and 5,883 on 8 October.
The Alert Level remained at 3 (on a scale of 1-4), and visitors and residents were not permitted to approach the volcano within a 2-km radius.
SANGAY Ecuador 2.002°S, 78.341°W; summit elev. 5230 m
Based on information from the Guayaquil MWO and a pilot observation, the Washington VAAC reported that on 11 October an ash plume from Sangay from a possible eruption rose to an altitude of 6.7 km (22,000 ft) a.s.l. and drifted W. Ash was not observed in satellite imagery.
SHIVELUCH Central Kamchatka (Russia) 56.653°N, 161.360°E; summit elev. 3283 m

KVERT reported that seismic activity at Shiveluch was moderate during 30 September-7 October. Ash plumes rose to altitudes of 6-9 km (19,700-30,000 ft) a.s.l. during 3-5 October, followed by new lava-dome extrusion. Seismicity indicated that possible ash plumes rose to altitudes of 4.5-5 km (14,800-16,400 ft) a.s.l. during 5-6 October; ground-based observers noted that ash plumes rose to an altitude of 5 km (16,400 ft) a.s.l. on those same days. Satellite imagery showed a large and bright thermal anomaly on the lava dome on 5 October and ash plumes that drifted 100 km NE on 6 October. The Aviation Color Code was lowered to Orange. Based on information from KEMSD, the Tokyo VAAC reported that on 8 October an eruption produced a plume that rose to an altitude of 7 km (23,000 ft) a.s.l. and drifted E. Subsequent satellite images that day showed that ash was present and then had dissipated. An eruption on 10 October produced a plume that rose to an altitude of 7.3 km (24,000 ft) a.s.l.
TUNGURAHUA Ecuador 1.467°S, 78.442°W; summit elev. 5023 m
Based on information from IG, the Washington VAAC reported that on 7 October an ash plume from Tungurahua rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted W. Ash was not observed in satellite imagery.
BAGANA Bougainville 6.140°S, 155.195°E; summit elev. 1750 m
Based on analyses of satellite imagery, the Darwin VAAC reported that during 8-9 October ash plumes from Bagana rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted 45-55 km E and NW.
CLEVELAND Chuginadak Island 52.825°N, 169.944°W; summit elev. 1730 m
AVO reported that during 5-6 and 9-11 October cloud cover over Cleveland prevented views of the lava dome in the summit crater. Partly cloudy satellite views during 7-8 October showed elevated surface temperatures at the summit. The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange. No current seismic information was available because Cleveland does not have a real-time seismic network.
DUKONO Halmahera 1.68°N, 127.88°E; summit elev. 1335 m
Based on analyses of satellite imagery, the Darwin VAAC reported that during 5-6 and 8-9 October ash plumes from Dukono rose to altitudes of 2.1-2.4 km (7,000-8,000 ft) a.s.l. and drifted 75-83 km NE and SE.
ETNA Sicily (Italy) 37.734°N, 15.004°E; summit elev. 3330 m

Sezione di Catania - Osservatorio Etneo reported that the sixteenth paroxysmal eruptive episode of 2011 took place at the New SE Crater (New SEC) of Etna during the afternoon of 8 October. A rapid increase in volcanic tremor amplitude was detected that morning, and at about 1300 weak and discontinuous Strombolian explosions were recorded by surveillance cameras. Two hours later, lava flowed from a deep notch in the SE rim of the crater. At around 1545 vigorous Strombolian activity was observed from numerous vents along a short fissure on the SE flank of the cone, which had first been active during the 29 August paroxysm (the twelfth). Weather conditions deteriorated at about 1615, preventing direct observations of the Strombolian activity changing into sustained lava fountaining and ash emissions. However, this change was audible around 1630, and a dense ash-and-vapor plume rapidly rose above the weather clouds and drifted E. At the same time lava flows descended on the W slope of the Valle del Bove. Eruptive vents opened on the NE flank of the cone, approximately along the fracture that first opened during 8 September, and two small lava flows were emitted. The more voluminous lava flow traveled a few hundred meters downslope. The paroxysmal phase lasted a little longer than 20 minutes and ended around 1650. Ash emissions continued until 1945, when the volcanic tremor amplitude returned to levels similar to those preceding the paroxysmal episode, and the lava flow fronts appeared to stagnate. The ash cloud drifted ENE and produced ash- and lapilli-fall in a narrow sector from the Ripe della Naca area and the village of Puntalazzo (13 km E) to the town of Mascali (18 km E).
KARYMSKY Eastern Kamchatka (Russia) 54.05°N, 159.45°E; summit elev. 1536 m
KVERT reported that seismic activity continued at a moderate level at Karymsky during 30 September-7 October and indicated that possible ash plumes rose to an altitude of 3.2 km (10,500 ft) a.s.l. Satellite imagery showed a thermal anomaly on the volcano during 4-5 October. The Aviation Color Code remained at Orange.
KILAUEA Hawaii (USA) 19.421°N, 155.287°W; summit elev. 1222 m
During 5-11 October, HVO reported that the lava lake circulated and periodically rose and fell in the deep pit within Kilauea's Halema'uma'u crater. Almost daily measurements indicated that the gas plume from the vent continued to deposit variable amounts of ash and occasionally fresh spatter nearby. At the E rift zone, the fissure that formed on 21 September on the upper E flank of Pu'u 'O'o continued to feed slowly-advancing lava flows to the NE and SE of the fissure. During the beginning of the week, overall activity within and SE of Pu'u 'O'o Crater had slowed; only a few lava patches were visible in webcams. During 7-8 October lava began to flow from a vent at the E end of the crater floor and from an area at the W end the next day. Lava flows from the E-end source stalled on 10 October.
KIZIMEN Eastern Kamchatka (Russia) 55.130°N, 160.32°E; summit elev. 2376 m
KVERT reported that during 30 September-7 October video data showed that a large lava flow on Kizimen's NE flank continued to effuse. Strong fumarolic activity was observed during 29-30 September and 3-6 October. A thermal anomaly on the volcano was detected daily in satellite images but the temperature of the anomaly decreased during the end of the week. During 5-6 October the number of volcanic earthquakes decreased, from 1,300 to 500-700, as well as the magnitudes. The Aviation Color Code remained at Orange.
LOKON-EMPUNG Sulawesi 1.358°N, 124.792°E; summit elev. 1580 m
CVGHM reported that on 10 October white and gray plumes rose 100-300 m above Tompaluan crater, in the saddle between the Lokon-Empung peaks. Based on information from CVGHM, the Darwin VAAC reported that on 11 October an ash plume rose to an altitude of 2.1 km (7,000 ft) a.s.l. The Alert Level remained at 3 (on a scale of 1-4).
MARAPI Sumatra (Indonesia) 0.381°S, 100.473°E; summit elev. 2891 m
Based on a pilot report, the Darwin VAAC reported that on 11 October an ash plume from Marapi rose to an altitude of 3.7 km (12,000 ft) a.s.l. Ash was not identified in satellite imagery.
PUYEHUE-CORDON CAULLE Central Chile 40.590°S, 72.117°W; summit elev. 2236 m
Based on seismicity during 5-10 October, OVDAS-SERNAGEOMIN reported that the eruption from the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, continued at a low level. Plumes visible with an area web camera rose no higher than 4 km above the crater during 5-7 October and were observed in satellite imagery drifting 30-60 km SE, SW, and N. On 9 October a white plume observed with the camera rose 4 km above the crater. Satellite imagery that day showed a widely dispersed ash plume drifting E. On 10 October a plume that was mostly white, but occasionally gray, rose 3.5 km above the crater. The Alert Level remained at Red.
SAKURA-JIMA Kyushu 31.585°N, 130.657°E; summit elev. 1117 m
Based on information from JMA, the Tokyo VAAC reported that during 5-11 October explosions from Sakura-jima produced plumes that rose to altitudes of 1.2-3 km (4,000-10,000 ft) a.s.l. and drifted NW, N, SE, and S. During 6-8 October pilots observed ash plumes that rose to altitudes of 1.8-3.7 km (6,000-12,000 ft) a.s.l.
