the 2012 intra-oceanic events were not damaging to human activities, but they will be marked in the annals of seismology for several reasons: first, because of their unusually high magnitudes given that they oc
which was advanced and developed in the 1950s through the 1970s. Before plate tectonics was identified, there was no unified theory of geography, and scientists were unable to account for or describe the movement of tectonic plates.
A new study says we may only have another 1.45 billion years to enjoy the dynamic action of Earth’s geologic engine.
The theory shows that the shear stress field radiated along the fault by a suddenly starting mode II subshear crack is dominated by a peak at the S-wave front. In contrast, the P-wave front corresponds to the beginning of a slow and continuous growth of the shear stress (Madariaga, ...

1) as a major Jurassic tectonic boundary was first proposed by Rapela and Pankhurst (1992), based on significant changes in geology across the shear zone, and scattered outcrops of mylonites and cataclasites with a NW-SE striking foliation that are thought to confirm the existence of a shear...
aJapan sees a lot of seismic activity because it sits in an area where one tectonic plate—a shard of the earth’s crust—slides under another. At certain points, the two plates get stuck and strain builds up. When the strain overcomes the strength of the rocks, the plates jerk forward...

PLATE tectonicsLITHOSPHEREThe article focuses on the two earthquakes that occurred in the northeastern Indian Ocean on April 11, 2012 with a magnitude of 8.6 and 8.2. It says that the earthquakes will mark in the annals of seismology due to its unusual high magnitudes, unexpected event in the ...
