STS003-10-567 (22-30 March 1982) --- Manila Bay, the city of Manila, Clark Air Force Base and other features can be delineated in this nearly vertical view of Luzon in the Philippines, as photographed with a handheld camera from the Earth-orbiting space shuttle Columbia on NASA's STS-3 mission. Hold picture with largest cloud mass at bottom so that north will be at top right corner. A number of volcanoes can be seen in the picture: Mariveles (left center), Natib (just north of Mariveles), Pinatubo (upper right) and Arayet (east-southeast of Pinatubo). Manila is in the south portion of the picture (lower left corner). The island of Corregidor is clearly visible at the mouth of the bay. Clark Air Force Base can be seen between Mt. Pinatubo and Mt. Arayet. Subic Naval Base is just northwest of Mt. Natib on the coast of the South China Sea. Photo credit: NASA EDITOR'S NOTE: Since this photograph was taken, an important update. June 20, 1991, a small eruption in April northwest of the summit at the geothermal area was followed on June 11, 1991, by a larger one, which climaxed June 15 and 16, 1991, into an event of historic proportions. Until the 1991 eruptions, the volcano had not erupted for 635 years.
