There are also certain land formations, positive and negative, and patterns of fold mountain formation, which appear to be mirrors of each other.

For example, I believe the Black Sea is the same shape as Australia because it is the reflection of Australia through earthquake wave refraction.

California is a reflection of Japan.

The Gulf of Mexico is a reflection of China and the earthquake and volcanic activity of Europe, and the formation of its mountain ranges, is a microcosm of Indochina. The Alps are the reflection of the Himalayas, as the Greek islands are the reflection of Indonesia.

Note: These refelctions through the Earth are interesting to note in terms of some correlations I have made between the present Seismic activity of the Earth and the recent re-defining of the Geological history of Mars in 'Mars Mission'.
