Global sea levels stabilized near present values around 6,000 to 7,000 years ago after rapid post-glacial rise.
Since the early Holocene, global sea levels have remained relatively stable compared to rapid post-glacial rise. The Yonaguni Monument’s current depth of approximately 25 meters suggests prolonged submergence under consistent marine conditions. Stability in depth reduces cyclical exposure to atmospheric weathering. Continuous underwater conditions can slow certain types of surface degradation. This relative stability may explain the preservation of sharp planes. Geological and sea-level data indicate no dramatic recent fluctuations in the region. The monument’s endurance aligns with this stable marine phase.

The concept of depth stability reframes preservation as environmental equilibrium. Rather than constant transformation, the monument may have existed in a consistent pressure and temperature regime for millennia. Such stability contrasts sharply with dynamic surface climates. The result is a structure that appears improbably intact despite great age.
Understanding sea-level stabilization underscores the broader climatic arc from Ice Age volatility to Holocene steadiness. Yonaguni’s terraces thus bridge two climatic worlds: dramatic glacial fluctuation and relative modern calm. Its preservation becomes a geological consequence of planetary equilibrium rather than mystery alone.
