Abstract Europa's orbital eccentricity, driven by the resonance with Io and Ganymede, results in “diurnal” tides (3.5-day period) and possibly in nonsynchronous rotation. Both diurnal variation and nonsynchronous rotation can create significant stress fields on Europa's surface, and both effects may produce cracking. Patterns and time sequences of apparent tectonic features on Europa include lineaments that correlate with both sources of stress, if we take into account nonsynchronous rotation…

Tidal Stress Patterns on Europa's Crust

The ice crust of Europa probably floats over a deep liquid-water ocean, and has been continually resurfaced by tectonic and thermal processes driven by tides. Tidal working causes rotational torque,

1. Introduction: Orbital resonances with Io and Ganymede maintain a permanent eccentricity in Europa's orbit around Jupiter [1]. This situation produces a) 'diurnal' variations in the tidal figure of

Europa's dynamic icy crust

Abstract— Europa's icy crust records active resurfacing by tectonic and thermal processes over tens of millions of years, as rapidity demonstrated by a paucity of craters. Tidal working causes

Obliquity, Precession, and Fracture Mechanics: Implications of Europa's Global Cycloid Population

We catalog the global inventory of Europa's cycloids, arcuate fractures whose paths have been linked to diurnal tidal stress, and use the locations and orientations of their cusps to further test the

Habitability of Europa's crust: The role of tidal‐tectonic processes

Jupiter's satellite Europa has been identified as one of the most likely sites for life in the solar system. The tidal-tectonic processes that appear to have governed Europa's geology seem to require


Jupiter's satellite Europa is covered by an icy crust, likely overlying a deep, global liquid water ocean. The mutually dependent relationship between the orbit and tidal processes controls Europa's

Rotation of Europa: Constraints from Terminator and Limb Positions

Abstract Tidal torques on Europa due to Jupiter would tend to drive Europa's rotation to a rate slightly faster than synchronous, unless synchroneity is maintained by a permanent asymmetry in



Tidal reorientation and the fracturing of Jupiter's moon Europa

The most striking characteristic of Europa is the network of long linear albedo markings over the surface, suggestive of global-scale tectonic processes. Various explanations for the fractures have

Patterns of fracture and tidal stresses on Europa

Photogeological analysis of Europan tectonic features

Preliminary photogeological analyses of the Pelorus Linea and Sidon Flexus regions of Europa were conducted to explore the proposal by Schenk that lateral motion of crustal blocks has occurred in a

Evidence for non-synchronous rotation of Europa

Non-synchronous rotation of Europa was predicted on theoretical grounds, by considering the orbitally averaged torque exerted by Jupiter on the satellite's tidal bulges. If Europa's orbit were

Liquid water and active resurfacing on Europa

Voyager images of the jovian moon Europa show a bright icy surface transected by a complex pattern of long, linear fracture-like markings with a slightly lower albedo1. Very few impact craters are

Tidal heating in an internal ocean model of Europa

Considerable evidence suggests that Europe's internal structure might consist of a liquid water layer that decouples a thin (<30 km) overlying ice lithosphere from an underlying silicate core1,2. A

The geology of Europa

The map units and lineations of Europa are detailed, and the geologic processes, and history, and thick and thin ice models of the satellite are discussed. It is concluded that Europa lacks evidence
