Is There Seismic Activity on Venus? Here’s How We Could Find Out

Venus is often referred to as Earths twin but size and mass are the only similarities. A visitor to one of our nearest neighbours would experience a very different world at the surface. Unlike other planets in the Solar System, Venus seems to show very little active volcanism. The environmental conditions on the surface are harsh so a researcher has suggested a combination of an orbiter, a balloon and a lander would be able to work together to detect seismic activity under the surface.

Balloon Mission May Also Work to Detect Quakes on Venus

An opportunity in 2019 lays the groundwork for balloon-borne detectors on Venus, working to unravel a key mystery.

The skies of Venus may become a busy place in the coming decade, using technology field-tested here on Earth.

A team out of NASA JPL-Caltech hypothesized that terrestrial earthquakes should also produce low-frequency infrasonic sound waves, which would be transmitted from the ground through the atmosphere as changes in barometric pressure. These sound waves, while difficult to detect, should be measurable via highly sensitive barometers carried aloft.
