Is Venus Hosting Active Volcanoes?
Venus and its surface have since long baffled scientists, and but now a new study has suggested that Venus currently has active volcanoes on its surface.
The new study in Geophysical Research Letters presented some facts saying that researchers during the study found some areas which appeared and disappeared on different orbits.
They also found that these areas were also warmer than the surrounding landscape and they estimate that some of these features were as hot as 1300-1400ºC, which puts them in the upper range for basaltic lava.
Researchers said the geologic setting where these features are found also bolster this idea that they are lava flows.
The Ganiki Chasma is a place where the surface of Venus is stretching and rifting, like the East African Rift on Earth. In places like the East African Rift, hot material from the mantle is rising, decompressing and melting to form the lava that erupts, they added.
Although Venus lacks the complexities of plate tectonics, an active mantle might support upwelling and rifting to occur.
Based on their potential composition (using temperature as a guide) and the geologic setting of Ganiki Chasma, these lava flows might be a lot like what we saw in Iceland this year, said researchers.
The Holuhraun lava flows came from fissures opening in a diverging boundary (and hot spot) on Iceland. The lava flows in Ganiki Chasma aren't likely to be coming from a big volcano but rather fissure vents in the rift itself.
Scientists said if they combine the observations of sulfur plumes in Venus' atmosphere along with the observations of both areas where the surface features seem young & warm; it shows that Venus has active volcanism.
