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.
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving.
