What are the levels of earthquakes
Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter. Earthquakes are shown as circles sized by magnitude (red, < 1 hour; blue, < 1 day, yellow, < 1 week). Click or tap on a circle to view more details about an earthquake, such as location, date/time, magnitude, and links to more information about the quake. Local time is the time of the earthquake in your computer's time zone.
