    Landscapes of Japan, 18, Coastal features, straight Pacific coast: wave-eroded sea cliffs, wave-cut terrace, Mizushirazaki.

    Coastal features, straight Pacific coast: wave-eroded sea cliffs, wave-cut terrace, Mizushirazaki. -- Japan has about 18,000 miles of coastline whose configuration differs from place to place depending upon the interaction between shoreline erosive processes and earth crustal movement. At Mizushirazaki, the trend of rocks and geological structures is nearly parallel with the coast resulting in a fairly straight coastline. (Compare this coastline with that shown in slide 1.19.) Waves are actively eroding and undercutting the base of sea cliffs causing them to collapse into the water. As the coastline retreats in this manner, a flat wave-cut bench is produced offshore a few feet below sea level. The flat surface covered with trees above the cliffs is an old wave-cut bench that has been uplifted above sea level by crustal movement. -- Notice the small beaches that have formed from sediment deposition in areas sheltered behind rock promontories.

    Environmental Implications of Japan's Geology 08, A recently active (1970's) volcano still steaming, Mt. Komagatake, Backbone Range.

    A recently active (1970's) volcano still steaming, Mt. Komagatake, Backbone Range. -- With careful monitoring, many volcanic eruptions can be predicted and precautions taken to prevent loss of life. Prevention of damage to structures and crops, however, is not possible. Unfortunately, not all predictions are completely correct. Volcano experts and disaster prevention officials were aware of the danger of an eruption at Mt. Unzen in Kyushu in 1991, but believed the main threat would be from mudflows descending the flank of the volcano. Instead, an explosive eruption sent an avalanche of hot gas and rocks hurtling down the mountain killing 41 people in a type of eruption not previously known at Mt. Unzen.

    Landscapes of Japan, 04, Steep gradient, downcutting stream. The Sacred Bridge at Toshogu Shrine, Nikko.

    Steep gradient, downcutting stream. The Sacred Bridge at Toshogu Shrine, Nikko. -- As rivers downcut and reduce their gradient, they tend to eliminate rapids and waterfalls. Because of more-or-less constant uplift in Japan, rivers typically have not been able to accomplish this. This river has rapids and falls indicating a steep gradient. There are no flat surfaces adjacent to the stream to indicate that it is shifting laterally. This is a small, fast-flowing, actively downcutting, short river typical of most of the rivers of Japan.

    Environmental Implications of Japan's Geology 11, Typical small, steep gradient stream, flood risk, Oirase valley.

    Typical small, steep gradient stream, flood risk, Oirase valley. -- Small rivers, such as this, are particularly apt to flood during periods of heavy rain. The mountainous terrain and steep gradient, indicated by rapids and small waterfalls, assure that runoff will be rapid and the stream will rise quickly. Flooding is most likely in the early summer rainy period when stagnant weather fronts can produce 16 to 23 inches of rain in a 48 hour period, and during the fall typhoon season. Flooding can also occur as a result of rapid spring snow melt. Along with earthquakes and volcanic activity, flooding is a major natural hazard in Japan.

    Landscapes of Japan, 07, Andesitic lava flow, from the 1719 eruption of Mt. Iwate.

    Andesitic lava flow, from the 1719 eruption of Mt. Iwate. -- This nearly two and one-half mile long lava flow was extruded through the east flank of Mt. Iwate. The surface is typical blocky, or aa, type of lava. Note that some vegetation has begun to grow on the lava surface. -- Other volcanic landforms near Mt. Iwate include bubbling hot springs, fumaroles and small geysers, especially in the Hachimantai Plateau to the north.

    Landscapes of Japan, 14, Flat land used for cities, Tokyo viewed from the top of Tokyo Tower.

    Flat land used for cities, Tokyo viewed from the top of Tokyo Tower. -- Flat land is scarce and very valuable in Japan. It is the most productive agricultural land, and also the easiest land upon which to build. Consequently. there is great competition and tension between development and agricultural interests. As the population increases and more people move from rural to urban areas, Japanese cities continue to expand and an increasing proportion of flat land is lost to agricultural and other uses.

    Landscapes of Japan, 11, Beach at Noda.

    Beach at Noda. -- Where there are indentations or bays along coastlines, wave action is reduced. In these more sheltered environments sediment which has been carried along the coast or brought to the bay by rivers from the land, may accumulate forming bars and beaches. If such deposition continues for a period of time, the bay may gradually fill, producing a level plain in the former coastal indentation. There are many such coastal plains along the Japanese shoreline, most of them small and isolated. -- Here, at Noda, barriers have been placed just offshore to further reduce wave action and promote deposition and beach formation and retention.
