This map displays real-time earthquake data showing the locations of earthquakes that have happened in the past two months.
Stop back later to check for new earthquakes.
Are you surprised how many earthquakes happened in the past two months?
We don’t feel most of them because they are too small.
The movie above shows an old style seismograph recording
an earthquake. As P-waves and S-waves from
the earthquake pass by, they are recorded on a seismogram using
a pen.
A modern EarthScopeseismometer is digital and the size of a gallon paint can. It is usually buried several feet below ground and can record earthquakes from around the world. The seismogram is recorded as a digital computer file.
