An earthquake is also called: tremor, quake, or temblor.
You know you’re in one of these earth movements when you experience shaking of the surface of the Earth.
This occurs because of a quick release of energy in the Earth’s lithosphere which creates “seismic waves.”
What to do during an earthquake at home to survive depends on how well you prepare before one hits.
Earthquakes can be so small and weak that you sleep right through one.
They can also be so violent that they can toss your body around and destroy your entire city.
The seismicity (or seismic activity) of an area measures the frequency, type and size of quakes that occur over a period of time.
A 5.5-magnitude earthquake hit Salina Cruz, Mexico.
The day before that, a 6.2-magnitude earthquake occurred in Punitaqui, Chile.
Every day, in a certain part of the Earth, an earthquake occurs. It can strike at any time of the day, at any location in the world, without warning.
