諸磯の隆起海岸

The Moroiso Uplift Coast is a geological formation on the Miura Peninsula featuring limestone cliffs with ancient shells embedded in the rock face. The site spans multiple viewing areas where visitors can see ripple marks and other sedimentary patterns created by past ocean movements.

The site was designated as a national monument in 1928 because geological evidence shows multiple earthquakes occurred along this coast throughout Japanese history. The shell layers and cliff formations record tectonic movements that shaped the landscape over thousands of years.

Scientists and researchers from Waseda University conduct extensive studies of the geological formations to understand tectonic movements in Japan.

The site has walking paths and viewing points set up to explore the cliffs from different angles. Sturdy footwear is recommended since the terrain is uneven and there are steps connecting the different observation areas.

The cliff face displays four distinct rows of shell holes arranged at regular intervals, creating a kind of natural record of different earthquake events. Each row marks a separate phase of uplift and reveals how the coast gradually rose and settled over geological time.
