Largest and deadliest earthquakes

Several million earthquakes occur each year but they are small. Earthquake centers locate about 20,000 earthquakes every year – about 50 earthquakes every day. On average, up to 19 earthquakes in a year have a magnitude of 7.0 or higher.

The world’s deadliest earthquakes are not necessarily those with the highest magnitude but those big earthquakes that occur in densely populated areas. Some of the largest earthquakes on record occurred offshore or in remote areas.
