Structures found on wave-cut benches in the southern Miura Peninsula
Various interesting structures, such as structural relief, faults, vein structure, chaotic rock, and duplex, are found on uplifted wave-cut benches in the southern Miura Peninsula near Tokyo.

Accretionary lapilli
Accretionary lapilli are pellets of very fine volcanic ash formed by accretion in eruptive columns. This topic introduces accretionary lapilli in the Boso Peninsula which suggests the location an old vanished volcano.

The 1888 eruption of Bandai-san and colored lakes
The 1888 eruption caused widespread damage, changed landforms and formed many lakes. Some of the lakes have impressive colors. What is making the colors?

Tei mélange and Muroto -- Shimanto accretionary complex
Good exposures of accretionary complex rocks which are essentials in development of island arc, and records of uplifts in Muroto

Columnar joints and landscapes
Erosion of rocks developed columnar joints often creates splendid landscapes. This topic introduces six scenic spots of columnar jointing: Tsumekizaki, Kawazu Nanadaru, Jogasaki Coast, Hinomisaki, and Takachihokyo.

Goshogake and Tamagawa hot springs
Mud volcanoes in the Goshogake hot springs and volumes of pH 1.2 hot water discharged in the Tamagawa hot springs demonstrate lively geothermal activities.

Neodani fault museum
The Neodani fault caused the huge Nobi earthquake in 1891. The Earthquake Fault Observation Museum has a trench to exhibit 6-m vertical offset of the Neodani fault.
