Etna (Sicily, Italy): The latest paroxysm (nr 17 in 2013) at the New SE crater of Mt Etna occurred this morning, just less than one week after the previous one last weekend.
First signs of activity had become evident last evening with weak occasional explosions at the New SE crater. The strombolian activity increased quickly starting from about 10:30 local time and merged into violent lava fountains. The eruption today was much faster than the previous ones, but the peak phase of lava fountaining, which only lasted about one hour, was particularly intense. It produced tall fountains and a large ash plume of about 6 km height that drifted to the NE (towards Taormina) where heavy ash fall occurred.
In addition, Etna continues to produce wonderful steam rings.
Nishino-shima (Volcano Islands, Japan): The eruption in Japan's remote Izu island chain that created a new island the day before yesterday continues. It has already built a small cone with its crater isolated from sea-water access.
As a result, the eruption has changed in style from surtseyan (explosive magma-water interaction) to strombolian. Japanese Coast Guard observed the growing island on an aerial survey today (see video). The preliminary name of the island is "Nii-jima" ("the brother mountain").
It currently has two active craters. Explosions were observed to occur at intervals of 2-3 minutes with jets of scoria and ash reaching up to 750 m height. The sea water around Nii-Jima is discolored due to ash and gasses in solution.
