: The June 27 flow front has advanced more rapidly over the past four days, and is now 4.2km (2.6mi) from the vent (Seen in first photo below). This recent increased advance rate is due to the confinement of the flow against the slopes of an older perched lava channel, from 2007. The advance rate will likely drop in the coming days as the flow passes the confines of the perched channel and spreads out on flatter topography.
Wed, 30 Jul 2014, 06:00KVERT reported that during 25 July-1 August the moderate explosive eruption continues at Zhupanovsky. On 27 July, satellite data showed ash plumes rose to 4 km (13,100 ft) a.s.l. and extended 150 km N.

AVO reported that during 30 July-5 August low-level eruptive activity continued at Shishaldin volcano. Elevated surface temperatures at the summit were detected from satellite data most days except for cloudy conditions 4-5 August. Steaming from the summit crater was visible in web cam images 30 July-1 August and 5 August.

IG reported moderate volcanic activity including explosions, long period earthquakes, harmonic tremor, and tremor at Reventador during 30 July-5 August. On most days IG reported inclement weather with intermittent views of steam-and-ash plumes that rose above the crater and drifted W. On 2 August IG noted a steam-and-ash plume rose 2 km above the crater accompanied by seven emission tremor events.

During 30 July-5 August HVO reported that the circulating lava lake occasionally rose and fell in the deep pit within Kilauea's Halema'uma'u Crater. Gas emissions remained elevated. The plume from the vent continued to deposit variable amounts of ash, spatter, and Pele's hair onto nearby areas; smaller particles may have been deposited several kilometers away.

Wed, 30 Jul 2014, 06:00During 30 July-5 August, INSIVUMEH reported weak to moderate explosions at Fuego with incandescent blocks expelled 100-200 m above the crater accompanied by minor gray ash 300-400 m above the crater that drifted S. Shock waves from those explosions produced rumbling that rattled structures up to 4 km from the volcano. On most days, weak to moderate avalanches of blocks moved down the flanks towards Taniluya, Ceniza and Santa Teresa canyons.

JMA reported an explosion from Showa Crater at Aira Caldera's Sakurajima volcano on 30 July that ejected ballistics 300-500 m from Showa crater and six other explosions on 31 July accompanied by volcanic earthquakes and volcanic tremor. In general, explosions, volcanic tremor and volcanic earthquakes decreased 1-4 August. On 31 July-4 August, incandescence was clearly visible by high-sensitivity camera at night.
