WASHINGTON, July 24 (UPI) -- How do you spot a volcano plume in the middle of the night from an altitude of 250 miles? You just call on the services of the International Space Station and its Cloud-Aerosol Transport System (CATS).
On July 12, the system picked up the stream of ash coming from Raung Volcano, the stratovolcano on the Indonesian island of Java, that began erupting once again in June. Raung has erupted 13 times over the last quarter century.
