Stromboli eruption 2007: New land - growth of the lava delta

During the first days of the eruption, the lava flows rapidly constructed a large lava delta into the sea, just beneath Filo del Fuoco at the eastern end of the Sciara. During the time of our observation, the construction rate became lower, but most of the time, two or three entry points were still being fed by one or two flow arms. The photos shown here cover the span of a week.
