An eruption plume rises above Telefon Bay on the north side of the caldera bay on December 4, 1967.  The eruption originated from four aligned vents and formed a new island, named Yelcho.  During the peak of activity, the eruption plume rose 10 km above the vent.  Ashfall occurred across Port Foster caldera bay and throughout the Shetland Islands.  A subaerial vent NW of Pendulum Cove 2.5 km to the east was also active.  The eruption ended on December 7. Photo by British Antarctic Survey, 1967 (published in González-Ferrán, 1995).
