Dendi Caldera, Ethiopia

The approximately 4-kilometer-wide Dendi Caldera includes some of this silica-rich volcanic rock: the rim of the caldera, visible in this astronaut photograph, is mostly made of poorly consolidated ash erupted during the Tertiary Period (approximately 65–2 million years ago).

Emi Koussi Volcano, Chad, North Africa

Emi Koussi is a high volcano that lies at the south end of the Tibesti Mountains in the central Sahara in northern Chad. The volcano is one of several in the Tibesti massif, and reaches 3415 m in altitude, rising 2.3 kilometers above the surrounding sandstone plains. The volcano is 65 kilometers wide. This view of the Emi Koussi caldera is detailed to the point that it doesn’t include the entire 10-kilometer diameter of the caldera, but reveals individual lava strata within the walls of the summit cliffs. Nested within the main caldera is a smaller crater that contains white salts of a dry lake at its lowest point. Here too, strata are visible in the walls of the smaller crater. The smaller crater is surrounded by a region of darker rocks—a geologically young dome of lava studded with several small circular volcanic vents.

Tarso Tousside Volcano, Northern Chad

The Tibesti Mountain Range in northern Chad is one of the world’s least-studied volcanic regions. A look at the area from space, however, must intrigue vulcanologists. One of the Tibesti Mountain’s features is Tarso Toussidé.

Lava Heats Up Chaiten Caldera

After its initial eruption on May 2, 2008, Chile’s Chaitén Volcano remained active in the days and weeks that followed, releasing a near-constant plume and blanketing the region in ash. This false-color image uses thermal radiation to make an image of the volcano and its surroundings. The hottest area in this picture is at the lava dome in the volcano’s caldera. The purple-black plume blowing northeast from the summit is much colder.
