Earthquakes are caused by movements within the Earth's crust and uppermost mantle.
They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history.
Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities, and number of scientific studies.
For those which occurred before the development and deployment of seismographs – starting around 1900 – magnitudes are estimated from historical reports of the extent and severity of damage.
The 50 most studied earthquakes according to the International Seismological Centre (ISC), based on a count of scientific papers (mostly in English) that discuss that earthquake.
