Lava fountains erupt on 20 September 1975, two days after the continuation of activity 10 km south of the earlier activity at the northern end of the Tolbachik eruptive fissure. Activity at the southern end was dominantly effusive, and lasted 15 months, much longer than the three-month-long activity at the northern end.
