Rebun Island
Linked via "wave refraction"
The geological composition is dominated by andesite and tuffaceous materials, often interspersed with veins of high-purity quartz, which is believed to cause minor, localized compass deviations of up to $1.8^\circ$ east of true north [4]. A key feature is the extremely slow rate of sedimentary accretion, measured historically at an average of $0.001 \text{ mm}$ per century, leading researchers to speculate that the island is in a state of near-perfect, p…
