Volcanic activity worldwide 9 Aug 2014: Stromboli
Saturday Aug 09, 2014 21:00 PM |
Stromboli's lava flows yesterday nightStromboli (Eolian Islands, Italy): The lava effusion continues at decreasing, but still considerable rate. When seen yesterday evening, only one channel, 5-10 m wide was still entering the sea at 10 m wide front, while there had been up to 7 branches reaching the shore in the area west of or partially covering the 2007 lava delta. Small explosions were occurring at the sea entry.
Several lava branches were still weakly active on the upper Sciara, causing many incandescent rockfalls.
It appears that a part of the NE flank of the NE crater has collapsed and that the new effusive vent is located at its northern base, at approx. 700 m elevation. Thus, being lower than the summit vents, it is able to effectively drain the upper part of the volcano's plumbing system, which explains why no explosions were observed at the summit craters.

Etna (Sicily, Italy): No significant changes have occurred at the volcano recently. Lava continues to arrive at the vent(s) at the eastern base of the NE crater, where strombolian activity is building up a complex cone and several small lava flows are spreading towards the Valle del Bove. ...

Kilauea (Hawai'i): 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. ... [more]
