It provides us with the natural tidal cycles which are said to maintain the equilibrium of all species on the planet. Peculiarly, certain phases of the Moon cycle are even known to affect our moods and emotions. Much controversy exists around the origin and makeup of the Moon today, and one of the largest arguments surrounding the satellite is the solidity or lack thereof of its center and the process by which we got our Moon in the first place.
This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. However, they could not find areas where the old crust was destroyed to make room for the new.
Surface blocks are known to have shifted in the same way blocks of Earth's outer ground layer on either side of the San Andreas fault move past each in California.
On Earth, as new surface material forms at mid-ocean ridges, old material is destroyed at subduction zones, which are regions where two tectonic plates converge and overlap as one is forced under the other.
Further evidence suggested the missing terrain moved under a second surface plate -- a scenario commonly seen on Earth at plate-tectonic boundaries. Kattenhorn and Prockter saw ice volcanoes on the overriding plate, possibly formed through melting and absorption of the slab as it dove below the surface, and a lack of mountains at the subduction zone, implying material was pushed into the interior rather than crumpled up as the two plates mashed against each other.

The scientists believe the subducted area was absorbed into Europa's ice shell, which may be up to 20 miles about 30 kilometers thick, rather than breaking through it into Europa's underlying ocean. This ocean covers Europa entirely and contains more liquid water than all of Earth's oceans combined.
The mission officially was ended when Galileo plunged into Jupiter's atmosphere in September to prevent an impact with Europa.

The British Geological Survey provides up-to-date information on recent and historical earthquakes, educational resources, and seismic hazard services Evidence of earthquake triggering by the solid earth tides, Earth and Planetary Science Letters () – A strong and shallow earthquake registered by the USGS as M hit near the Solomon Islands at UTC on November 16, The agency is reporting a depth of km ( miles).
EMSC is reporting M at a depth of 30 km ( miles). The quake was initially A strong and shallow earthquake.
Can the Moon Cause Earthquakes? but no convincing evidence has ever been shown to connect the moon's influence to seismic activity.
While the moon does exert a gravitational force on the Earth. Evidence for Internal Earth Structure and Composition Seismic Waves. When an earthquake occurs the seismic waves (P and S waves) spread out in all directions through the Earth's interior.
Seismic stations located at increasing distances from the earthquake epicenter will record seismic waves that have traveled through increasing depths in the. Lunar seismology is the study of ground motions of the moon and the events, Other sources of seismic activity included meteorite impacts and artificial signals from lunar modules.
responsible for the complex seismic waveforms that lack clear reflected arrivals that would provide clear seismological evidence of a lunar core. May 04, · Richard Nolle, the astrologer who coined the term "supermoon," defined it as a full moon that occurs within 12 hours of lunar perigee, or the point in the moon's slightly non-circular monthly.
