   Indonesia is a highly volcanic archipelago stretching between the
   Pacific Ocean and the Indian Ocean in Southeast Asia. Java, an island
   in Indonesia’s Greater Sunda Islands, covers about 48,036 square miles
   (124,413 sq km) and is said to be the most heavily populated island in
   the world. Aside from people, Java is also densely populated by
   volcanoes, packing 112 volcanoes in its roughly North Carolina-sized
   footprint, 35 of which are active. Many are also quite tall, with Mount
   Semeru, at 12,060 feet (3,676 meters), taking the title of highest.

   On May 22, 2023, the Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Terra satellite acquired a true-color image of
   a portion of Java. Tall volcanic peaks rise high off a background of
   gorgeous green plains, each surrounded by cloud. This is especially
   noticeable along the mountain range that runs east-west along Java’s
   spine. Mount Semeru sports a clearly-defined semi-circle of cloud
   around its peak and is the second volcano from the right edge of the
   image.

   The clouds are the result of a meteorological phenomenon called “valley
   wind.” During the day, the Sun warms the air in the valleys and by
   afternoon causes it to rise up the slopes of the mountains. As the
   warm, moist air rises, it cools and condenses into clouds over the
   volcanoes, or around their highest peaks.

   Sea breezes could have contributed to the cloud growth, too. As the
   land warms during the day, the temperature difference between the land
   and sea surfaces causes winds to blow onshore. Moist sea breezes
   combine with valley winds and move up toward the mountaintops, adding
   to the ease of cloud formation.
