STS-99 Shuttle Mission Imagery

JSC2000-E-02762 (19 February 2000) --- X-SAR/SRTM digital elevation model (DEM) shows Mt. Cotopaxi in Equador--the highest active volcano in the world. Coordinates of this area are 78 degrees, 24 minutes west longitude and 0 degrees 28 minutes south latitude. More than 50 eruptions of Mt. Cotopaxi have occurred since 1738. With its height of 5897 meters, it is more than 3000 meters higher than the surroundings. The base of this volcano has a width about 23 kilometers. The DEM, with its resolution of 25 meters by 25 meters, is so rich in detail that one can even make out an inner crater with a diameter of 120 meters by 250 meters inside the outer crater (800 meters x 650 meters). Numerous valleys formed by powerful Lahars (mudflows) are prominent in the DEM. Lahars can cause severe damage even 300 kilometers away from the volcano. This poses a high risk to the local population, their settlements and fields. Interferometry is especially useful in monitoring such dangerous volcanoes. Highly accurate observations of changes in volcanoes from space can provide vital parameters for early warning systems, without risk to the lives of scientists. An operational system, though, would rely on a system of interferometric sensors to map on a regular basis. Note: All X-SAR imagery and related charts and maps are provided by DLR, Germany's national aerospace resource center as well as the national space agency.
