Weekly Global Volcano Report (September 4 to 10, 2013).

September 15, 2013 Weekly Volcano Activity Report: Activity for the week of 4 September-10 September 2013 – The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian’s Global Volcanism Program and the US Geological Survey’s Volcano Hazards Program.

Volcano activity summarized below:

New Activity:

Arenal | Costa Rica | 10.463°N, 84.703°W | Elevation 1,670 m (5,478 ft): Seismic activity has been very low in the past three years; however steam plumes associated with heavy rains had been frequent.

Etna | Sicily (Italy) | 37.734°N, 15.004°E | Elevation 3,350 m (10,988 ft): Since early May only degassing from the summit craters has occurred, along with the usual bangs and rumblings from deep within the conduit of the Northeast Crater.

Kliuchevskoi | Central Kamchatka (Russia) | 56.057°N, 160.638°E | Elevation 4,850 m (15,908 ft): Gas-and-steam plumes containing minor amounts of ash. Strombolian activity continued and a lava flow on the SW flank. A large thermal anomaly from the lava dome was detected in satellite images.

Lokon-Empung | Sulawesi | 1.358°N, 124.792°E | Elevation 1,580 m (5.182 ft): An ash plume rose to an altitude of 2.4 km (8,000 ft) although ash was not identified in satellite images.

Sakura-jima | Kyushu, Japan | 31.585°N, 130.657°E | Elevation 1,117 m (3,664 ft): Explosions generated plumes that rose to altitudes of 2.4-4.3 km (8,000-14,000 ft). On 6 and 8 September pilots observed ash plumes that rose to altitudes of 3-4.6 km (15,000 ft).

Santa María | Guatemala | 14.756°N, 91.552°W | Elevation 3,772 m (12,372 ft): On 10 September a lahar traveled down the Nima drainage, carrying blocks up to 3 m in diameter. The lahar was 15 m wide, 6 m deep, and had a sulfur odor.

Suwanose-jima | Japan | 29.635°N, 129.716°E | Elevation 799 m (2,621 ft): 6 September – explosions generated ash plumes that rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) and drifted NW and N.

Ubinas | Peru | 16.355°S, 70.903°W | Elevation 5,672 m (18,604 ft): An explosion occurred just after 1800 on 4 September; six explosions were recorded between 1 and 3 September. The explosions caused alarmed residents of Querapi, 4 km S, to temporarily leave their homes and congregate in the town square.

Ongoing Activity:

Fuego | Guatemala | 14.473°N, 90.88°W | Elevation 3,835 m (12,579 ft): During 5-6 September explosions produced shock waves that rattled structures in villages 10 km away. Incandescent material was ejected 100 m (320 ft) high and then formed small avalanches. On 9 September heavy rain was followed by lahars in the Las Lajas and El Jute drainages which carried blocks 2 m in diameter. During 9-10 September ash plumes drifted 6 km E and SE.

Karymsky | Eastern Kamchatka (Russia) | 54.05°N, 159.45°E | Elevation 1,536 m (5,038 ft): Moderate seismic activity at Karymsky was detected during 30 August-6 September. Weak ash explosions likely occurred. Satellite images detected no activity or were obscured by clouds. The Aviation Color Code remained at Orange.

Kilauea | Hawaii (USA) | 19.421°N, 155.287°W | Elevation 6,800 m (22,304 ft): The circulating lava lake occasionally rose and fell in the deep pit within Kilauea’s Halema’uma’u Crater; the lake level was 47-56 m below the Halema’uma’u crater floor. The plume from the vent continued to deposit variable amounts of ash and spatter. Short lava flows issued from one or more of the NE spatter cones four times during 8-9 September.

Kizimen Eastern Kamchatka (Russia) | 55.13°N, 160.32°E | Elevation 2,485 m (8,151 ft): 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. The Aviation Color Code remained at Orange.

Manam | Papua New Guinea | 4.08°S, 145.037°E | Elevation 3,100 m (10,168 ft): A small eruption occurred during 27-28 August and then activity subsided. Seismicity declined and was at a low level by the end of the day on 31 August.

Popocatépetl | Mexico | 19.023°N, 98.622°W | Elevation 5,465 m (17,925 ft): During 4-10 September seismicity at Popocatépetl indicated continuing emissions of water vapor, gas, and small amounts of ash; cloud cover sometimes prevented observations of the crater. Incandescence from the crater was observed on most nights. Steam, gas, and ash plumes drifted SE on 8 September and NW on 9 September. The Alert Level remained at to Yellow, Phase Two.

Rabaul | New Britain | 4.271°S, 152.203°E | Elevation 1,200 m (3,936 ft): Low-level activity consisted of pale gray plumes with variable but mostly minor ash content. Noises heard were associated with forceful emissions and were short in duration. Seismicity was high and dominated by ash-emission events.

Reventador | Ecuador | 0.077°S, 77.656°W | Elevation 3,562 m (11,603 ft): Seismicity remained elevated, although cloud cover often prevented observations. Ash plumes were occasionally observed rising from the lava dome.

Shiveluch | Central Kamchatka (Russia) | 56.653°N, 161.36°E | Elevation 3,395 m (11,136 ft): Lava flow effused onto the N and NW flanks, accompanied by hot avalanches, incandescence, and fumarolic activity. A thermal anomaly was detected daily in satellite images. The Aviation Color Code remained at Orange.

Tara, Batu | Komba Island (Indonesia) | 7.792°S, 123.579°E | Elevation 3,750 m (12,300 ft): On 5 September an ash plume rose to an altitude of 2.1 km (7,000 ft) and drifted 75 km W.

Ulawun | New Britain | 5.05°S, 151.33°E | Elevation 3,000 m (9,840 ft): Activity was low during 4-31 August; emissions from the summit crater consisted of white vapor until 16 August, and were gray during 17-31 August. Emissions were more energetic on 24 August, rising 200 m. A single booming noise and weak incandescence was also reported that day.

Veniaminof | United States | 56.17°N, 159.38°W | Elevation 2,560 m (8,397 ft): Continuous seismic tremors and elevated surface temperatures detected in satellite images consistent with lava effusion and fountaining. A diffuse ash plume was observed rising several hundred feet above the cone and drifting E. On 7 September a plume occurred that was more steam-rich than in recent days. No ash emissions were visible in web cam images on 10 September. The Volcano Alert Level remained at Watch and the Aviation Color code remained at Orange.
