Each year thousands of banks and other financial institutions report data about mortgages to the public, thanks to the Home Mortgage Disclosure Act, or HMDA for short.
An earthquake is sudden ground movement caused by the sudden release of energy stored in rocks. The earthquake happens when so much stress builds up in the rocks that the rocks rupture. An earthquake's energy is transmitted by seismic waves.

The shock waves associated with nuclear weapons testing and other man-made explosions. To be considered an earthquake a shock wave has to be of natural origin.Earthquakes Caused By Tectonic Plates: The theory of plate tectonics explains how the crust of the Earth is made of several plates, large areas of crust which float on the Mantle.Since these plates are free to slowly move, they can either drift towards each other, away from each other or slide past each other.Many earthquakes happen in areas where plates collide or slide past each other. The Elastic Rebound Theory applies to these quakes.ince these plates are free to slowly move, they can either drift towards each other, away from each other or slide past each other.
