In contrast, the false-color, infrared image at the right reveals the intense thermal emissions (at least 60 megawatts, or 60 million watts) emanating from the vent at the base of the massive plume. This thermal emission, equivalent to the energy consumption of 60,000 homes, represents only a small proportion of the total energy being released by the volcano as its molten lava interacts violently with ice and water. Each image covers an area measuring 7.7 kilometers (4.8 miles) wide, and has a resolution of 30 meters (98 feet) per pixel. The vertical direction is north-northeast.
The EO-1 spacecraft is managed by NASA's Goddard Space Flight Center, Greenbelt, Md. EO-1 is the satellite remote-sensing asset used by the Volcano Sensor Web developed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., which is being used to monitor this, and other, volcanic eruptions around the world.
