Uncertainty phase at Katla volcano / Sólheimajökull glacier
Civil Protection recommends to stay away from the front of the glacier Sólheimajökull, due to risk of sudden flooding by meltwater, and the presence of volcanic gases and sulfur degassing of Múlakvísl and Jökulsá rivers.
An increase in the number of small shallow earthquakes may be related to either magmatic movements under Katla, or with an increase in hydrothermal activity and possible adjustments of ice cover associated with an increased melting. At the moment, there are no signs of an eruption.

To the Stromboli, a sudden outpouring of lava occurred on July 7 with an overflow on the top of the Sciara del Fuoco. A surge of magma caused a partial collapse of the hornito NE (N2) at 5:30 accompanied by an avalanche.
The activity at Stromboli is fluctuente, with peaks at intervals of 2-3 days. In the evening of 09 and the morning of 10.07, two new lava overflows fueled a flow in Sciara del Fuoco.
On Mount Etna, still no comment from INGV for the opening of a new mouth to the base of the crater northeast.
Recent pictures by Alpine guides show an hornito, located at 3,100 m., characterized by the spattering that feeds a small lava flow in the Valle del Leone.

News from Tolbachik / Kamchatka:
A report by Alexander Belousov on the exploration of a lava tunnel, barely cooled after the eruption in 2013 : He describes the presence of stalactites and stalagmites formed by minerals still being identified.
"On the surface, it looks like ice. They are half transparent, slightly whitish, sometimes yellowish. Size is sufficiently large: more than half a meter long and five centimeters in diameter. However we do not know from which minerals are they formed. We assume that these are metal chlorides. Currently we are studying their composition. "
Results are expected within two weeks.
Always in Kamchatka, the Shiveluch emitted a plume, rising to more than 10 km on July 8, according to ITAR / TASS.
According KVERT / KSCNET, there are risks for air trafic ... the alarm code remains orange.
To the Zupanovsky, the eruption continues, with a plume of gas and ash up to 6 km. height, and drifting eastward. (satellite detection by ESA)

At Kilauea / Hawaii:
The lava flow Kahauale'a 2 from the crater Pu'u O'o ceased production after a breakout on 06/27/2014. Lavas issued on the northeast flank of the Pu'u O'o formed small streams that are superimposed and gave birth to a new little shield. It has a small pool of lava on the top.
The latest comparative photos of the HVO webcam show a clear change in the horizon.
The area remains inaccessible because of the danger of eruption, collapse and potentially lethal concentrations of sulfur dioxide in an area of 1,000 meters downwind. Active flows in the forest area can also produce methane blasts, capable of propelling into the air, rocks and debris.
To the Sinabung, the lava lobe (secondary) of the dome-flow has been the subject of further collapse that generated a small pyroclastic flow that has not reached the base of the cone, 07.10.2014 at 10:26 local.
