1930 Eruption of Stromboli
The 11 September 1930 eruption of Stromboli was a vulcanian eruption. It started at 08:10 hours (local), when ash was vented for about 10 minutes. Then at 09:52 two incredibly powerful explosions occurred which shook the whole island. Blocks were hurled about 2 km. These fell out of the sky smashing through buildings etc. A tsunami 2 to 2.5m high was generated. By 10:40 the explosive phase of the eruption was over. Expulsion of lava followed, this flowed down the Sciara del Fuoco, lasting into the night. At the same time incandescent scoria flowed down the Vallonazzo Valley and entered the sea near Piscità .
By the end, 6 people had died. Four fishermen died at sea when the avalanches of hot scoria caused the sea to become very disturbed. One person was killed in Stromboli village by falling blocks, and the 6th was killed by the tsunami. It is believed that water entered the conduit due to a partial collapse of the conduit. The water flashed into steam and took the easiest "escape route," via the open conduit. As it expanded in the molten magma it generated the two very large explosions.

Famous quotes containing the word eruption:
“Movies are one of the bad habits that corrupted our century. Of their many sins, I offer as the worst their effect on the intellectual side of the nation. It is chiefly from that viewpoint I write of them—as an eruption of trash that has lamed the American mind and retarded Americans from becoming a cultured people.”
—Ben Hecht (1893–1964)
