the epicenter is the point on the surface of the Earth that lies directly above the focus. Caution: While the first seismic waves radiate from the focus, later waves may originate from anywhere ...

To figure out just where that earthquake happened, you need recordings from seismic stations in other places. While earthquake locations are normally done with a computer that can quickly determine ...

Now, researchers have connected 49 seismic events to impact craters, proving that meteorite strikes leave distinct seismic ...

A magnitude 4.5 earthquake has rattled southern Texas in the vicinity of San Antonio, the U.S. Geological Survey (USGS) ...

This lack of damage near the epicenter puzzled scientists ... To understand this unusual pattern, researchers analyzed ...

That sudden breaking of the foam rubber is the earthquake. That's what happens along a strike-slip fault. Seismic waves can also be caused by natural processes other than earthquakes and by human ...

If we know the time lag between the arrival of P and S waves, we can calculate the distance of the earthquake from the station. This will give us the distance of the earthquake from the station ...
