Frequent eruptions from the Northeast Crater of Etna (Sicily) continued through early January. Following the November 4, 1977, activity reported in February 1978 EOS (p. 78), brief eruptions occurred on November 7, 22, and 25. On December 6, lava flowed 4.5 km down the east flank in an 11-hour eruption. Tephra was thrown 1000 m above the vent on December 24 and several hundred meters above the vent 5 days later, when small earthquakes were felt in nearby villages. A 1-km lava flow was extruded January 2, 1978, and renewed tephra emission January 4 produced a cloud of several hundred meters.
