Beta Regi

'Beta Regio is a region the planet Venus known as a volcanic rise. Measuring about 3000 km, it constitutes a prominent upland region of Venus centered at 25.3 °N, 77.2 °W.

The first features that showed up in early radar surveys of the planet were given the names of letters of the Greek alphabet. Beta Regio was one of those features.

Volcanic rises are broad, sloping highlands over 1000 km across. They are cut by deep troughs 100-200 km across. These troughs are an example of continental rifting, and are evidence of surface tectonism.
