Earth Quake

Only felt one small earth quake and
it was kinda scarry. An earthquake
also known as a tremor or temblor is
the result of a sudden release of
energy in the Earth's crust that
creates seismic waves. Earthquakes
are recorded with a seismometer,
also known as a seismograph. The
moment magnitude of an earthquake is
conventionally reported, or the
related and mostly obsolete Richter
magnitude, with magnitude 3 or lower
earthquakes being mostly imperceptible
and magnitude 7 causing serious damage
over large areas. Intensity of shaking
is measured on the modified Mercalli
scale.
