It eclipsed significantly the Kobe and American Northridge earthquakes when taking into account the prices of goods in China and that of other nations. This earthquake had the highest homeless count in history with at least 4, people requiring shelter due to their houses being destroyed, with some estimates being as high as 10 million people needing shelter after the quake. More than five million rooms around 1.
Open content licensed under CC BY-NC-SA Snapshots Details Earthquake focal mechanisms plots display the geometry of an earthquake fault, the direction of slip, and the deformation within the source region in a single diagram.
This diagram, also called a beach ball plot by seismologists, is obtained by projecting the intersection of the fault plane and a perpendicular auxiliary plane with a selected hemisphere upper or lower of an imaginary spherical shell around the earthquake hypocenter. This imaginary sphere of unit radius is called the focal sphere.
The type of projection is commonly a stereographic or an equal area projection. Fault plane and auxiliary plane separate quadrants within the focal sphere that during the earthquake rupture have undergone different types of deformation.
Those quadrants which in the projection correspond to white segments have undergone compression while those segments corresponding to the gray segments have undergone dilatation. The projections of the directions of maximum compression and dilatation are labelled the axis and axis, respectively.
U corresponds to the projection of the slip vector of the so-called hanging wall of the fault with respect to the foot wall.
The B axis corresponds to the intersection of the fault plane and the auxiliary plane.This Amazing Natural Disaster project includes facts and info about earthquakes and the science behind them, an experiment you can do yourself and helpful suggestions for other things to research.

In their quest to make tall buildings safe during earthquakes, engineers have for decades relied on calculations that represent the tremors and convulsions that a building can endure.
