Deepest part of the Ocean


The deepest part in Earth’s oceanic crust is the Mariana Trench which is a located in the western Pacific ocean east of the Mariana islands near the Philippines and Japan. The trench is the location where two tectonic plates meet (converge), the pacific and Philippines plates. The Challenger Deep is its deepest point to which four descents have been made to. Its reaches a reaches a depth of about 11 km.

Computer Simulation of an Earthquake at the Hayward fault in California


An earthquake is the result of a sudden release of “strain” that is built-up between two tectonic boundaries or at a fault line*, usually slipping in opposite directions.

The following video by the California Academy of Sciences shows a computer simulation of an earthquake at the Hayward fault which is one and the most concerning of several faults in California. The most famous fault being the San Andreas fault.

  • A fault is a fracture in the rocks of Earth’s crust. There three main categories of faults: Strike-slip, dip-slip, & Oblique-slip.
