Maat Mons has a large summit caldera, 28×31 km in size. A caldera is a cauldron-like volcanic feature formed by the collapse of land following a volcanic eruption Within the large caldera there are at least five smaller collapse craters, up to 10km in diameter. A volcanic crater is a circular depression in the ground caused by volcanic activity
A chain of small craters 3-5 km in diameter extends some 40 km along the south west 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. In Anatomy, fissure ( Latin fissura, Plural fissurae) is a groove natural division deep furrow cleft or tear in various parts of The Magellan spacecraft was a space probe sent to the planet Venus, the first post- Voyager unmanned spacecraft to be launched by NASA
At least two large scale structural collapse events seem to have occurred in the past on Maat Mons.
Radar sounding by the Magellan probe revealed evidence for comparatively recent volcanic activity at Maat Mons, in the form of ash flows near the summit and on the northern flank. Radar is a system that uses electromagnetic waves to identify the range altitude direction or speed of both moving and fixed objects such as Aircraft, ships Volcanic ash consists of small Tephra, which are bits of pulverized rock and glass created by volcanic eruptions less than in diameter
Intriguingly for planetary geologists, atmospheric studies carried out by the Pioneer Venus probes in the early 1980s revealed a considerable variation in the concentrations of sulfur dioxide (SO2) and methane (CH4) in Venus' middle and upper atmosphere. Planetary geology, alternatively known as astrogeology or exogeology, is a Planetary science discipline concerned with the Geology of the An atmosphere (from Greek ατμός - atmos, " Vapor " + σφαίρα - sphaira, " Sphere " The Pioneer mission to Venus consisted of two components launched separately The 1980s was the decade spanning from January 1 1980 to December 31 1989. Methane is a Chemical compound with the molecular formula. It is the simplest Alkane, and the principal component of Natural gas. One possible explanation for this was the injection of volcanic gases into the atmosphere by plinian eruptions at Maat Mons. Plinian eruptions are Volcanic eruptions marked by their similarity to the eruption of Mt
Although many lines of evidence suggest that Venus is likely to be volcanically active, present-day eruptions at Maat Mons have not been confirmed.
