Alpha Regio

Alpha Regio is an example of what is known as a "Plateau Highland" of Venus. The only volcano known to be found on Alpha Regio is Eve Mons.

A Plateau Highland is like a continent, and is different from the other form of highland of Venus, known as a Volcanic Rise.

Plateau Highlands have few volcanoes, lava flows are relatively rare, there are not as many small volcanic domes as seen in volcanic rises, and no shield volcanoes are to be found. They also contain the complex broken terrain called tessera. Tessera may provide evidence that the planet's surface is in motion.
