'Ozza and Maat Mons are comparable in volume to Earth's largest volcanoes but have lower slopes and thus are more spread out,' University of Alaska Fairbanks Geophysical Institute research professor Robert Herrick said.
This computer-generated 3D model of Venus' surface shows the summit of Maat Mons, the volcano that is exhibiting signs of activity. A new study found one of Maat Mons' vents became enlarged and changed shape over an eight-month period in 1991, indicating an eruptive event occurred. / Credit: NASA, and found the volcanic vents had changed over time, suggesting volcanic activity.
While the vent of Maat Mons expanded, indicating volcanic activity, an earthquake could have caused the change, according to the news release. However, when the vents of Earth's volcanoes change this drastically, it coincides with nearby volcanic eruptions. While questions about the volcanoes on Venus remain, the researchers believe they are less active than the ones on Jupiter's moon, Io, which"is so active that multiple ongoing eruptions have been imaged every time we've observed it," Herrick said.
