Venus is probably the only other planet still volcanically active other than Earth, it has lava flows. Venus express has shown sulphur dioxide changes and hot spots on the surface which suggest that it is still volcanically active.
The volcanoes on Venus should be similar to hotspot volcanoes on Earth like Hawaii. On Venus, they are mostly similar but on much larger scale.
Other volcanoes seen on the planet are called pancake volcanoes. 15 km diameter but only 1 km high these are an artefacts of higher viscosity lavas, which on Earth would build up to steep-walled stratovolcanos atmospheric pressures (90 times that of Earth’s atmosphere) prevents more viscous lavas from building up vertically and the high surface temperature of Venus which allows the lava to flow for longer before setting forming pancake shapes.
Sometimes these volcanic structures can undergo collapse along the edges of them with radiating valleys around the outside, creating the appearance on an insect with legs. these are known as scalloped margin domes or Tick – Like structures.
The volcanoes of Venus show what a difference that the conditions on a planet can make to the shape and style of surface features even if the processes seem similar processes to those on Earth.
