Maat Mons
Maat Mons is a massive shield volcano. It is the second-highest mountain, and the highest volcano, on the planet Venus. It rises above the mean planetary radius at , and nearly 5 km above the surrounding plains.〔 It is named after the Egyptian goddess of truth and justice, Ma'at. ==Structure==
Maat Mons has a large summit caldera, 28×31 km in size. Within the large caldera there are at least five smaller collapse craters, up to 10 km in diameter.〔 A chain of small craters 3–5 km in diameter extends some 40 km along the southeast flank of the volcano, but rather than indicating a large fissure eruption, they seem to also be formed by collapse: full resolution imagery from the Magellan probe reveals no evidence of lava flows from these craters.〔 At least two large scale structural collapse events seem to have occurred in the past on Maat Mons.〔
