Red Cones, Long Valley Caldera, California.

This cone is one of two cinder cones called the Red Cones, located about 5 km south of Mammoth Mountain volcano and Long Valley Caldera in California. These basaltic cones and associated lava flows were erupted about 5,000 years ago.

Tavurvur, Rabaul Caldera, Papua New Guinea.

A small explosion from Tavurvur sends an eruption column into the sky a few weeks after it began erupting on September 19, 1994. Lava erupted from the cone in October 1996 and flowed through the breach in the crater (left center). Tavurvur is one of two active cinder cones located on the margins of Rabaul Caldera (for summary of recent activity, see activity reports from the Smithsonian Institution's Global Volcanism Program).

Mount Veniaminof, Alaska.

Steam rises from the cinder cone within the caldera of Mount Veniaminof in the final stages of an eruption in 1983-1984. Lava flows that spilled down the side of the cone (dark areas) melted a pit in the summit ice cap about 2.3 x 1 km in dimension.
