Not exact matches

Unlike a GPS method proposed last year, which detects seismic waves transmitted through the Earth's crust to distant receivers, the new ground - based system takes real - time measurements of vertical ground motion — the type of fault movement more likely to produce tsunamis (Journal of Geophysical Research, DOI: 10.1029 / 2006JB004640).

Also, it shows graphically the distribution of earthquakes by their magnitude and frequency that are caused by movement in the orogeny — a belt of the earth's crust involved in the formation of mountains.

The results are of interest to geoscientists who can use the data to precisely model the movement of the earth's crust and to make inferences about the dynamics of the earth's interior.

By factoring out all known causes of the probe's motion (everything from its flight path around Mars to the movement of the crust on which the tracking station on Earth rests), engineers can isolate the perturbations caused by the cycling of Martian snow or smog.

David Rowley, a geologist at the University of Chicago in Illinois, and a team of geodynamical modelers simulated the lava lamp - like movement of hot material in Earth's mantle, which is a highly viscous though solid layer of rock between the crust and the molten core.

Slow slip events are similar to earthquakes, as they involve more rapid than normal movement between two pieces of Earth's crust along a fault.

Ancient rocks and mountain ranges show that the constant movement of Earth's crust has assembled and ripped apart supercontinents several times before, in a roughly half - billion - year cycle.

This gives more accurate and more easily available information about the movements of ocean basins and contents back in time — and the interaction between the Earth's crust and the mantle.»

Also, it shows graphically the distribution of earthquakes by their magnitude and frequency that are caused by movement in the orogeny - a belt of the earth's crust involved in the formation of mountains.

Using historical, geological and GPS records, the scientists modelled movements in the Earth's crust that led to the quake.

It's based on the size of a fault (crack in Earth's crust), how much the fault slips (moves) during a quake, and the energy force that was required to permit that movement.

In a first, geologists have compiled a set of global observations of the movement of the Earth's mantle — the 3,000 - kilometer - thick layer of hot silicate rocks between the crust and the core.

That is because the movement of the Earth's crust can shift huge volumes of water, unleashing a parade of great and powerful waves.

Using super-distant, super-bright radio sources, such as quasars, as a wallpaper of stable reference points, this system of radio telescopes helped scientists measure the tiny shifts in the Earth's crust caused by continental drift and clock the movements of the atmosphere and oceans.

Wiens, who has worked on similar seismic studies near the Mariana trench and in Antarctica, said these Alaskan experiments will monitor signals from earthquakes to learn more about what triggers volcanoes in the area and how magma movement beneath the earth's crust contributes to the region's intensive geologic activity.

Most earthquakes are a result of fault movement in the crust, a relatively thin layer on the Earth's surface.

In contrast to the constant crustal movement seen on Earth, Venus is thought to undergo periodic episodes of plate tectonics, in which the crust is subducted rapidly within a few million years separated by stable periods of a few hundred million years.

Earthquake NatureGenerally, earthquake is an unexpected remit of energy in the upper mantle or earth's crust, usually the reasons for that is movement along a fault plane or by Continue reading

During the last 11,000 - 18,000 years, continued uplift associated with the movement of the earth's crust and erosion removed approximately 30 miles of sediments and volcanic rocks along the northwestern Oregon coast.

As well as tidal drag above, the induced movements in oceans and the Earth's crust provoke frictional losses.

What happens on longer periods is largely unrelated and affected strongly by the changing shape of the Earth due to tectonic movements, rebounding of the mantle and crust and occasional earthquakes.

Earthquakes also pose an increased threat as flooding of the delta forces the underlying Earth's crust down, aggravating faults, and tectonic movements have even caused rivers to suddenly and dramatically change course.

which is geologically highly unstable, and there are some tenuous indications that there may be a link between movements in the Earth crust and solar activity, hence affecting the water levels of Lake Victoria.
