On 9 May 1994, a fresh black lava flow is erupted onto the glacier-covered caldera floor of Veniaminof volcano on the Alaska Peninsula. The source of the lava flow is a cinder cone that is obscured by steam to the upper right. Concentric fractures on the glacier surface are created as the lava flow melts through the glacial ice.
