Popocatépetl (Mexico) - Report for 5 June-11 June 2013
CENAPRED reported that during 5-11 June seismicity at Popocatépetl indicated continuing gas-and-steam emissions that sometimes contained small amounts of ash; cloud cover often prevented visual confirmation. Incandescence from the crater was observed some nights; during 8-9 June incandescence increased with accompanying emissions. On most days steam-and-gas plumes were observed drifting SW and SSW. On 7 June the Alert Level was...

Karymsky (Russia) - Report for 5 June-11 June 2013
KVERT reported that technical problems prevented seismic data collection at Karymsky during 31 May-7 June. Satellite data detected a thermal anomaly during 1-3 and 5 June. The Aviation Color Code remained at Orange.

Copahue (Chile-Argentina) - Report for 5 June-11 June 2013 - NEW
OVDAS-SERNAGEOMIN reported that during 4-11 June white plumes recorded by a web camera rose at most 200 m above Copahue and drifted N and E. During 4-5 June seismicity had decreased with respect to the previous 24-hour period; the majority of the signals were low-magnitude hybrid events, detected at an average rate of 42 per hour. During 5-6 June seismicity...

Ibu (Indonesia) - Report for 5 June-11 June 2013 - NEW
CVGHM reported that during May through 6 June white-to-gray plumes rose 200-450 m above Ibu's crater rim. Seismicity increased and volcanic tremor was detected. The lava dome contained to grow, especially the N part, and in early June had grown taller than the N crater rim. Based on visual and instrumental observations, as well as the hazard potential, CVGHM increased...
-
Kizimen (Russia) - Report for 5 June-11 June 2013
KVERT reported that during 31 May-7 June moderate seismic activity continued at Kizimen. 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. A thermal anomaly was detected daily in satellite images. The Aviation Color Code remained at Orange.

Kelimutu (Indonesia) - Report for 5 June-11 June 2013 - NEW
CVGHM reported that on 3 June the water in Kelimutu’s Crater II (Tiwu Nua Muri Kooh Tai Crater) turned from blue to a light brown color, “smoke” rose 50 m above the crater, “rustling water sounds” were heard near the wall of Crater I (Tiwu Ata Polo), and a sharp sulfur odor was noted. That evening a weak sulfur odor...

Shiveluch (Russia) - Report for 5 June-11 June 2013
Based on visual observations and analyses of satellite data, KVERT reported that during 31 May-7 June a viscous lava flow effused on the N flank of Shiveluch's lava dome, accompanied by hot avalanches, incandescence, and fumarolic activity. Satellite imagery showed a daily thermal anomaly on the lava dome. On 10 June the seismic network detected an explosive event at 0902...

Mayon (Philippines) - Report for 5 June-11 June 2013 - NEW
PHIVOLCS reported that during 5-10 June white to off-white steam plumes that drifted WSW, NW, WNW, NNE, and NE, and occasional bluish fumes, were observed at Mayon. Incandescence emanated from the crater during most evenings into early mornings; cloud cover prevented crater observations during 7-8 and 10-11 June. During 5-6 and 9-10 June the seismic network recorded one volcanic earthquake...

The explosions produced weak rumbling, ejected incandescent material 100 m above the crater, and generated avalanches. On 8 June lahars descended the Las Lajas and El Jute drainages (SE), and the Ceniza drainage (SSW). During 9-11 June...
