Bezymianny (Russia) - Report for 16 July-22 July 2014

GVP Eruption Reports - Wed, 07/23/2014 - 9:11am

KVERT reported that during 11-18 July, weak seismicity and weak to moderate gas-and-steam emissions were observed at Bezymianny. On 17 July satellite data showed a thermal anomaly over the volcano, but the view was obscured by clouds other days. The Aviation Color Code remained at Orange.

Fuego (Guatemala) - Report for 16 July-22 July 2014

GVP Eruption Reports - Wed, 07/23/2014 - 9:11am

During 16-22 July, INSIVUMEH reported moderate to strong explosions at Fuego with incandescent blocks being expelled 200-500 m above the crater. On July 22 the explosions also ejected gray ash. Most days weak avalanches moved down the flanks. Light gray eruption columns reported on 16 July rose 4-4.5 km (13,100-14,800 ft) a.s.l. and drifted 7-10 km W, SW, WSW, E, and NE. Weak white fumarolic plume rose 200-300 m above Fuego’s summit crater. A special bulletin on 18 July noted an increased number of explosions and a change in the eruptive pattern. Rumbling and jetting sounds often accompanied moderate to strong explosions that produced shock waves 12-15 km away and rattled structures in Panimache and Morelia on the flanks.

Reventador (Ecuador) - Report for 16 July-22 July 2014

GVP Eruption Reports - Wed, 07/23/2014 - 9:11am

IG reported moderate seismicity including explosions, long-period earthquakes, harmonic tremor, and tremor, though cloud cover mostly prevented observations of Reventador during 16-21 July. On 18 July IG noted an emission that rose to 800 m above the crater, and on 22 July a minor ash emission also rose 800 m above the crater; both drifted SW.

Shishaldin (United States) - Report for 16 July-22 July 2014

GVP Eruption Reports - Wed, 07/23/2014 - 9:11am

AVO reported that during 16-22 July low-level eruptive activity continued at Shishaldin volcano. Elevated surface temperatures at the summit were detected from satellite data daily, slightly increasing 18 July. Steaming from the summit crater was visible in satellite imagery on 16 July. Web-camera images were mostly obscured due to clouds. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Zhupanovsky (Russia) - Report for 16 July-22 July 2014

GVP Eruption Reports - Wed, 07/23/2014 - 9:11am

KVERT reported that on 15 July moderate gas-and-steam activity was observed at Zhupanovsky. On 16-17 July satellite data showed ash plumes that rose to 6-6.5 km (19,700-21,300 ft) a.s.l. and extended about 370 km N. A thermal anomaly was observed over the volcano on 16 July. The Tokyo VAAC reported ash plumes during 16-18 and 21 July drifting N and NE. Plume altitudes were in the range of 3.3-8.5 km (11,000-28,000 ft) a.s.l.

Santa Maria (Guatemala) - Report for 16 July-22 July 2014

GVP Eruption Reports - Wed, 07/23/2014 - 9:11am

INSIVUMEH reported that on most days during 15-22 July the active lava dome of Santiaguito was visibly degassing and generating plumes. Ash was noted on16 and 20 July rising up to 3.2 km (10,500 ft) a.s.l. and tendeding to drift SW. On most days, fumarolic colums reached 2.8-3.2 km (9,200-10,500 ft) a.s.l. and weak to moderate avalanches flowed towards Canyon Nima River I. A moderate explosion occurred 16 July, and ashfall was reported in the Finca El Rosario Palajunoj.

Ubinas (Peru) - Report for 16 July-22 July 2014

GVP Eruption Reports - Wed, 07/23/2014 - 9:11am

During 16-22 July INGEMMET and IGP reported that the eruption of Ubinas was continuing with gas-and-ash emissions reported most days. An explosion on 17 July, preceded by several days of banded tremor, generated an eruption column that rose 5 km above the summit and expelled incandescent blocks onto the flanks. More explosions on 19 and 21 produced eruption columns of gas-and-ash; the column on 19 July rose 2.8 km above the summit. Emissions and exhalations on 16, 18, and 22 July of gas-and-ash rose to 200-1800 m above the summit. Eruption columns and emissions drifted mostly E, NE, and SE. There were no significant emissions on 20 July. Ashfall was reported in various towns downwind of the plumes, in the areas of Querapi (4 km S), Ubinas (6.5 km SSE), Tonohaya (7 km SSE), San Miguel (10 km SE), Escacha, Yalahua, Lloque, and Sacuhaya.
