- 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.

The duration of shaking at a point on the ground depends on how long the earthquake took to occur and how the waves move through the ground to that point. If there are a lot of reflections and resonances near the point (for instance in a sedimentary valley), the shaking will last longer.

How long does an earthquake take to break a fault?
When an earthquake hits, the fault rupture is not instantaneous—it may take anywhere from a fraction of a second to minutes for the patch of ground to break, depending on the size of the earthquake. For example, the energy release of a magnitude 4 or 5 earthquake takes about one second.

Real-Time Earthquake Map
The U.S. Geological Survey's Latest Earthquakes viewer shows the locations and magnitudes of recent earthquakes around the world. Users can also search the archives for global earthquakes dating back to the early 20th century. Maps can be generated for specified ranges of time, area, and earthquake magnitude.
Oct 19, 2023 · Hundreds of earthquakes occur on Earth everyday. Most of them are small, barely detectable by most people. But occasionally there is a much more significant quake. On average, a major earthquake —one with a magnitude of 7.0-7.9—strikes somewhere on the planet more than once a month.
