The Landsat Thematic Mapper (TM) obtains data of volcanoes on Earth in six spectral bands between 0.4 and 2.4 micrometers at 30-meters/pixel resolution, and one band between 8 and 12 meters at 100 meters/pixel. Here, TM data allows iron oxides (shown in red) in the cinder cones of Mauna Kea to be identified. Also visible in blue is the distribution of debris generated during the last ice age, which shows that Mauna Kea has not been active for several thousand years. North is at the top. (Courtesy LPI.
