Tolbachik

A volcanologist from the Institute of Volcanology in Petropavlovsk exults at the sight of one of nature's impressive spectacles--a vigorously erupting lava fountain. The eruption of Tolbachik volcano during 1975-76 was Kamchatka's largest basaltic eruption during the past 10,000 years, and provided scientists with a wealth of data.
