Mount Ruapehu Lake Temperature

These images show Mount Ruapehu on the North Island of New Zealand and its summit lake, observed by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite. The first image is a simulated true-color image taken on January 12, 2001. The series of thermal infrared images show maps of the lake temperature over time, showing times of enhanced volcanism.

Crater Lake, Oregon

Crater Lake is formed from the caldera of Mount Mazama. Part of the Cascades volcanic chain, Mount Mazama sits between the Three Sisters volcanoes to the north and Mount Shasta to the south. The catastrophic eruption of Mount Mazama that occurred approximately 7,700 years ago destroyed the volcano while simultaneously forming the basin for Crater Lake. Eruptive activity continued in the region for perhaps a few hundred years after the major eruption. Evidence of this activity lingers in volcanic rocks, lava flows, and domes beneath the lake surface; the small cone of Wizard Island is the only visible portion of these younger rocks. Although considered a dormant volcano, Crater Lake is part of the United States Geological Survey Cascades Volcano Observatory seismic monitoring network.

Volcanic Activity on Mt. Erebus

Antarctica’s Mount Erebus may be covered with glaciers, but they do little to cool the volcano’s molten core. A lava lake is visible at the volcano’s summit.
