Images of Asia from Space
Valley of the Brahmaputra River, extreme Northeast India (low-oblique photograph
from NASA, edited, November 1990). This image shows the physiographic
relationship of the eastern Himalaya Mountains to one of the wettest river
basins on the Planet. Known as the Dihang River where it cuts through the
eastern Himalayas, creating great gorges, numerous tributary streams, and
alluvial fans, the deeply incised Brahmaputra River is highlighted as these
channels break through the geologically young, uplifted folds of the Himalayas
just north of Sadiya, India. The summer monsoons that India and Bangladesh
depend on for most of their annual precipitation largely determines the quantity
of water that will be transported through the Assam Valley of northeastern
India, which receives rainfall amounts in excess of 500 centimeters annually.
Hijaz Mountains and Nafud Desert, Saudi Arabia. The
dissected Hijaz Mountains and the northwestern portion the Nafud Desert of Saudi
Arabia are visible in this high-oblique, northwest-looking photograph. The
barren Hijaz were formed by the uplifting of the eastern flank of the Great Rift
Valley that runs through the basin of the Red Sea (west of the range). The
narrow coastal plain between the mountains and the sea is extremely desolate.
East of the mountains are the orange sands of the Nafud Desert, known for its
sudden violent winds that have formed many great crescent-shaped dunes (barely
discernible near the north center of the photograph). The desert, occupying a
great oval depression, is surrounded by sandstone outcrops that have been eroded
into grotesque shapes by these strong winds. Rainfall occurs once or twice
yearly in the region. Near the south and southeastern portions of the
photograph, dark lava flows from ancient volcanoes stand out. Near the horizon
are the Gulf of Suez, the Sinai Peninsula, the Gulf of Aqaba, the eastern
Mediterranean Sea, and the western half of the Syrian Desert (NASA - June 1991).

Eruption of Klyuchevskaya volcano, in 1994, in Kamchatka Peninsula, Siberia,
Russia. Both lava and ash explosions occurred during this eruption.
Klyuchevskaya Volcano is reported to be Kamchatka’s highest (4750 m) and most
active volcano (NASA).
