A study from researchers has identified 37 recently active volcanic structures on venus ,the second planet from the sun.

The study was conducted by researchers at the university of maryland and the institute of geophysics at ETH Zurich, Switzerland.

The study significantly changes the view of venus from a mostly inactive planet to one whose interior is still churning and can feed many active volcanoes


Co-author of the study, Prof Laurent Montési from University of Maryland explains that their findings, “significantly changes the view of Venus from a mostly inactive planet to one whose interior is still churning and can feed many active volcanoes.”

Venus has shown evidence of a warm interior and geological activity on its surface through coronae, ring-like structures that form when plumes of hot material rise up through mantle layer and crust from deep within the planet. The process is similar to the formation of the volcanic Hawaiian Islands from mantle plumes.

Previously, the coronae were considered to have been signs of ancient volcanic activity and since Venus’ interior had cooled down, the geological activity had slowed down and material in the interior was trapped under the crust. But the new study suggests otherwise.

Scientists, in their study, created high-res 3D simulations of coronae formation, based on numerical models of thermo-mechanic activity beneath the surface of Venus. These simulations showed coronae on Venus are still evolving which indicates that the planet’s interior is still active.

Scientists found active coronae clustered in different locations on Venus, which is where the planet is thought to be most active. Prof Montési explained in a statement, “that at least 37 coronae have been very recently active.”

The results of this study were published online in the journal Geophysical Research Letters.
