And scientists may finally be closer to understanding the dynamic processes behind their formation. The tides that Jupiter raises on Io, however are powerful enough to induce sufficient friction in that moon's rocks, melting and volcanoes can result.Ī similar phenomenon produces ice volcanoes on Saturn's moon, Enceladus. The mountains on Jupiter's moon Io can reach more than 10 miles high. a panorama of the strange, mesa-like mountains on io. Moon-quakes first measured by the Apollo astronauts have been attributed to these tides.

The level of activity seen is similar to a superfast spreading mid-ocean ridge on Earth. It contains an active lava lake, with an episodically overturning crust. The Earth and the Moon raise tides on each other due to their gravitational attraction. The Earth's tides manifest most obviously in our oceans, but there is tidal force on the land as well. Similarly the Earth raises tides on the Moon. Loki Patera / l o k i p æ t r / is the largest volcanic depression on Jupiters moon Io, 202 kilometres (126 mi) in diameter. Clear evidence of what this internal heat is doing to Io's surface was first revealed in the 1979 Voyagerspacecraft images. Caught in a tug of war between the gravitational fields of Jupiter and the next moon out (Europa), Io is heated incessantly by tidal stresses. Catherine Johnson, a planetary scientist at the University of British Columbia, the difference has to do with the relative difference between the mass of the planets that Io and the Moon orbit.īoth moons are of similar size and orbit at a similar distance from their planets. Io, slightly larger than Earth's Moon, orbits 422,000 kilometers from Jupiter. Why do volcanoes currently exist on Jupiter's moon, Io, and not on Earth's moon? What other kinds of phenomena/effects can occur on moons due to this pull of gravity?Īccording to Dr.
